Pritrjeni kondenzatorji za uporabo v elektronski opremi - Vrste standardnih števil za upore in kondenzatorje

Ta mednarodni standard podaja vrste standardnih vrednosti za upornost uporov in kapacitivnost kondenzatorjev.
Opredelitev take vrste z določeno numerično rešitvijo je osnovni predpogoj za označevanje in kodiranje kondenzatorjev in uporov z njihovimi vrednostmi kapacitivnosti in upornosti, kot je določeno v standardu IEC 60062.
OPOMBA Vrste števil, opredeljene v tem standardu, so osnovane na progresivnih razmerjih r 10, npr. 1210, ker je r = 3 · 2i, pri čemer je i celo število v med 0 in 6.
Ta sistem progresivnih razmerij je bil uveden pred objavo prve različice tega standarda leta 1952 kot posledica standardizacije toleranc pri ±5 %, ±10 % in ±20 % in s tem povezane komercialne prakse. Sprejetje prakse ISO, osnovane na sistemu 10 10, je bilo smatrano za nedosegljivo.

EN 60063:2015 - Preferred number series for resistors and capacitors

Overview

EN 60063:2015 (identical to IEC 60063:2015) defines the preferred number series (E series) used to specify resistance and capacitance nominal values for resistors and capacitors. These preferred values - e.g. E3, E6, E12, E24, E48, E96, E192 - provide a consistent numeric resolution that underpins value marking, coding and commercial interchangeability. The standard explains the generation of two‑ and three‑significant‑digit series, the relationship between an E series and component tolerances, and guidance for deducing an E series or tolerance from component marking. EN 60063:2015 includes editorial updates and clarifications on tolerance relationships and marking deductions compared with prior editions.

Key topics

  • E series definitions
    • Two‑digit series: E3, E6, E12, E24 (decimal multiples and submultiples with two significant digits).
    • Three‑digit series: E48, E96, E192 (values listed with three significant digits).
  • Generation method
    • Series are derived from a geometric progression and rounded to the required significant digits; historic rounding produces a few conventional deviations (e.g., some E24 values).
  • Tolerance vs. E series
    • Recommended pairings link tolerance bands to E series (examples):
      • E3 for tolerances wider than ±20%
      • E6 for ±20%
      • E12 for ±10%
      • E24 for ±5%
      • E48 for ±2%
      • E96 for ±1%
      • E192 for tighter than ±1%
    • For capacitors, practical practice often limits numeric resolution (two significant digits) and commonly uses E24 up to ±1% tolerance.
  • Marking and coding
    • Guidance on how numeric coding (per IEC 60062) implies possible E series/tolerance when explicit tolerance marking is absent; cautions about ambiguity and necessity for clear documentation.

Applications

  • Ensures consistent nominal values for designing and sourcing resistors and capacitors in electronic equipment.
  • Supports PCB designers, component engineers, procurement and inventory management by standardizing available values and minimizing overlap between tolerance bands.
  • Useful in component marking, coding and labeling processes where limited marking space requires inference from numeric resolution.

Who uses this standard

  • Component manufacturers and test houses
  • Electronic design engineers and PCB designers
  • Purchasing, quality and regulatory teams in electronics industry
  • Standards bodies and test laboratories

Related standards

  • IEC 60062 - Marking codes for resistors and capacitors (coding and marking schemes referenced by EN 60063)
  • ISO 3 - Preferred numbers (background on preferred number series)

EN 60063:2015 is essential when you need predictable nominal values, harmonized tolerances and reliable marking/coding practices for electronic passive components.

PREFERRED NUMBER SERIES FOR RESISTORS AND CAPACITORS
FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.

The article discusses the International Standard SIST EN 60063:2015, which provides preferred number series for resistors and capacitors used in electronic equipment. These series of values are important for marking and coding capacitors and resistors with their respective capacitance or resistance values. The series defined in this standard are based on progressive ratios of r 10, where r is equal to 3 multiplied by 2 raised to the power of i, with i being a whole number from 0 to 6. This system of progressive ratios was established before the first edition of the standard in 1952 due to standardization of tolerances and commercial practices. The adoption of ISO practice, based on a 10 10 system, was not considered achievable.

제목: SIST EN 60063:2015 - 전자 장비용 고정 커패시터 - 저항기 및 커패시터의 용량을 위한 선호하는 수열 시리즈 이 국제 표준은 저항기의 저항력과 커패시터의 전하용량을 위한 선호하는 값의 시리즈를 제공합니다. 이러한 시리즈의 정의는 IEC 60062에서 설명된 대로 커패시터와 저항기를 각각의 전하용량 또는 저항력 값과 함께 마킹하고 코딩하는 데 필수적입니다. 참고로, 이 표준에서 정의된 숫자 시리즈는 r = 3 · 2i (r은 10의 i승이며, i는 0부터 6까지의 자연수)의 점진적 비율에 기반하여 정의되었습니다. 예를 들어, 1210의 경우입니다. 이 점진적 비율 시스템은 ±5 %, ±10 % 및 ±20 %의 허용오차와 관련된 상용 관행을 바탕으로, 이 표준의 첫 번째 버전인 1952년 이전에 이미 확립되었습니다. 10 10 시스템을 기반으로 한 ISO 실천 방식의 채택은 달성 가능성이 없다고 여겨진 적이 없습니다.

この記事では、SIST EN 60063:2015という国際規格について解説しています。この規格は、電子機器で使用される固定コンデンサに対して、抵抗の優先値およびコンデンサの容量の優先値の系列を提供しています。これらの優先値の系列は、コンデンサや抵抗器の容量や抵抗値を表示および符号化するための基本的な前提条件です。この規格で定義されている数列は、r = 3 · 2i（iは0から6の整数）という等比数列を基にしています。この等比数列のシステムは、±5 %、±10 %、および±20 %の許容偏差と関連する商業慣行に基づいて、この規格の初版が1952年に発表される前に確立されました。10 10システムに基づくISOの慣行の採用は実現不可能と考えられていました。

이 기사는 전자 장비에서 사용되는 고정 커패시터에 대한 SIST EN 60063:2015 규격에 대해 설명한다. 이 국제 표준은 저항의 우선값 및 커패시터의 용량에 대한 우선값 계열을 제공한다. 이러한 우선값 계열의 정의는 용량이나 저항 값과 같이 커패시터와 저항기를 표시하고 부호화하기 위한 기본적인 전제 조건이다. 이 표준에서 정의한 수열은 r = 3 · 2i (i는 0에서 6 사이의 정수)로 나타내어진 등비수열에 기반한다. 이 등비수열 시스템은 ±5 %, ±10 % 및 ±20 %의 허용편차와 관련된 상업 관행에 따라 1952년 첫 번째 판이 발표되기 이전부터 존재했다. 10 10 시스템을 기반으로 한 ISO 관행을 적용하는 것은 가능성이 없다고 여겨져왔다.

記事タイトル：SIST EN 60063:2015 - 電子機器用の固定コンデンサ - 抵抗器およびコンデンサのための優先数列 この国際規格は、抵抗器の抵抗値とコンデンサの容量のための好ましい数列を提供します。 この数列の定義は、IEC 60062で説明されているように、コンデンサと抵抗器をそれぞれの容量または抵抗値と共にマーキングおよびコーディングするために基本的な前提条件です。 注：この規格で定義された数列は、r = 3 * 2i（rはiの10乗、iは0から6までの整数）の進行比に基づいています。例えば、1210の場合です。 この進行比のシステムは、±5％、±10％、および±20％の許容差を考慮した標準化と関連する商業的な慣行に基づいて、本規格の初版が1952年にリリースされる前に確立されました。 10の10乗のシステムに基づいたISOの実践の採用は、達成可能性が考慮されたことはありませんでした。
