Fixed resistors for use in electronic equipment - Part 4: Sectional specification: Power resistors for through hole assembly on circuit boards (THT) or for assembly on chassis

This part of IEC 60115 is applicable to fixed power resistors for use in electronic equipment. This standard relates to resistors having a rated dissipation typically greater than 1W up to and including 1000W for use in electronic equipment. This standard is applicable to fixed power resistors with a maximum surface temperature (MET) higher than the preferred upper category temperature (UCT) of 200°C. These resistors are typically described according to types (different geometric shapes) and styles (different dimensions) and product technology. The resistive element of these resistors is typically - protected by a conformal lacquer coating or - cement coating or - vitreous enamel or - a ceramic body or - any other housing, which is to be described in the relevant specification. The electrical connection of these resistors is typically achieved by means of - lead wire terminations or - punched terminals or lug terminals or - push on terminals or - screw terminals or - any other termination, which is to be described in the relevant specification In special cases, a heat sink may be applicable but not mandatory. The object of this standard is to prescribe preferred ratings and characteristics and to select from IEC 60115-1 the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of resistor. Test severities and requirements prescribed in detail specifications referring to this sectional specification shall be of equal or higher performance level, because lower performance levels are not permitted

Overview

The FprEN IEC 60115-4:2025/FprAA:2025 standard, developed by CLC, specifies requirements for fixed power resistors designed for electronic equipment. This part of the IEC 60115 series focuses on power resistors intended for through-hole assembly (THT) on circuit boards or direct assembly on chassis. It applies to resistors with rated power dissipation greater than 1W and up to 1000W, suitable for robust electronic applications where power handling and reliability are critical.

This standard governs fixed power resistors with maximum surface temperatures (MET) exceeding the preferred upper category temperature (UCT) of 200°C. It defines parameters such as preferred ratings, characteristics, testing methods, and quality assessments, ensuring compliance with stringent performance and safety requirements across global markets.

Key Topics

  • Scope and Applicability
    Applies to fixed power resistors with rated dissipation from >1W to 1000W, designed for through-hole mounting on printed circuit boards or chassis assembly. Suitable for high-temperature environments with MET above 200°C.

  • Resistor Types and Styles
    Covers various resistor types distinguished by geometric shapes and physical dimensions. Includes different product technologies tailored for specific applications and power ratings.

  • Protective Coatings and Housings
    The resistive element must be protected by one of the following:

    • Conformal lacquer coating
    • Cement coating
    • Vitreous enamel
    • Ceramic body or other specified housings
  • Electrical Terminations
    Electrical connections can be made using:

    • Lead wire terminations
    • Punched or lug terminals
    • Push-on or screw terminals
    • Other termination types specified in detailed product documentation
  • Heat Dissipation Considerations
    Use of heat sinks is optional but may be applied in special cases to enhance power dissipation and reliability.

  • Quality and Testing
    The standard specifies preferred test severities and general performance requirements, referencing IEC 60115-1 for quality assessment procedures, test methods, and measurement standards. Lower performance levels than those specified are not permitted, ensuring high reliability.

Applications

  • Electronics Manufacturing
    Utilized in the mass production of electronic equipment requiring stable power resistors capable of handling high dissipation loads.

  • Circuit Board Assembly
    Designed for through-hole technology (THT) assemblies, these power resistors are suited for PCBs with high current or heat dissipation needs.

  • Chassis Mounting
    Suitable for mechanically robust applications requiring resistors mounted directly on device chassis for efficient heat management.

  • Industrial and Consumer Electronics
    Applicable in various sectors including industrial machinery, automotive electronics, telecommunications, and consumer devices where fixed power resistor reliability is critical.

Related Standards

  • IEC 60115-1: Generic Specification for Fixed Resistors
    Provides foundational quality assessment and test methods referenced in this standard.

  • IEC 60115-2: Low Power Film Resistors for THT Assembly
    Details specifications for low power resistors complementing the high-power focus of Part 4.

  • IEC 60068 Series: Environmental Testing
    Outlines general environmental test procedures used to verify resistor durability and reliability.

  • IEC 60062 and IEC 60063: Marking Codes and Preferred Number Series
    Define coding and sizing conventions employed in resistor manufacturing and identification.

  • IEC 61193-2: Quality Assessment Sampling Plans
    Supports the statistical quality limits (SVQL) utilized in product inspection and acceptance.

By meeting the criteria outlined in FprEN IEC 60115-4:2025/FprAA:2025, manufacturers ensure that fixed power resistors are reliable, durable, and capable of performing safely in demanding electronic applications. This standard supports engineers and manufacturers seeking compliant, standardized components that meet international safety and performance benchmarks.
