Fixed resistors for use in electronic equipment - Part 2: Sectional specification: Low-power film resistors with leads for through-hole assembly on circuit boards (THT)
This part of IEC 60115 is applicable to fixed low-power film resistors with termination leads for use in electronic equipment, which are typically assembled in through-hole technology (THT) on circuit boards. 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. These resistors have wire terminations and are primarily intended to be mounted on a circuit board in through-hole technique. 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. Since the documents of the 60115-X series are exempted from the parallel procedure (D162/C089), this New Work Item Proposal aims to endorse the main IEC document IEC 60115-2:2023 as a European standard. The standard shall be published together with the finalised Common Modifications.

Overview
The FprEN IEC 60115-2:2025/FprAA:2025 standard, developed by the CLC (European Committee for Electrotechnical Standardization), specifies the requirements for fixed low-power film resistors equipped with leads for through-hole technology (THT) circuit board assembly. These resistors, widely used in electronic equipment, feature wire terminations and are typically protected by a conformal lacquer coating to ensure reliability and durability. This standard provides detailed guidance on preferred ratings, characteristics, quality assessment, and test methods according to the main IEC 60115-2:2023 document, adapted with European common modifications.
Key Topics
Fixed Low-Power Film Resistors
Targeted at resistors with low power dissipation designed for mounting via leads on printed circuit boards.Through-Hole Technology (THT)
Emphasizes resistors intended for assembly by insertion into holes drilled through PCBs, ensuring mechanical stability and reliable soldering.Product Types and Styles
Resistors are classified by geometric shapes (types) and dimensional variations (styles) suitable for diverse electronic applications.Conformal Lacquer Coating
Protective coating applied to resistive elements, enhancing environmental resistance and operational longevity.Quality Assessment and Testing
Specifies standardized procedures for sampling, environmental testing, and measurement techniques aligned with IEC 60115-1:2020 and associated environmental standards (IEC 60068 series).Preferred Ratings and Characteristics
Outlines typical electrical performances such as resistance values, tolerance, temperature coefficients, and power ratings to streamline component selection.European Modifications and Implementation
Incorporates common modifications for European harmonization, ensuring compliance across CENELEC member states.
Applications
General Electronic Equipment
Suitable for use in consumer electronics, industrial control systems, and communications devices requiring stable, fixed resistance components.Circuit Board Assembly
Ideal for through-hole PCB assembly, favored in applications where enhanced mechanical stability is essential or surface-mount technology (SMT) is not preferred.Prototyping and Repair
Facilitates easy insertion and replacement in prototyping stages and repair operations due to accessible leaded terminal design.High-Reliability Environments
The lacquer protection and defined quality tests make these resistors well-suited to applications demanding long-term stability under varying environmental conditions.
