Overview

EN 140401-802:2007/A2:2013 (CLC) is a CENELEC amendment that updates the European detail specification for fixed low power film SMD resistors - rectangular - stability classes 1 and 2. The amendment (A2, published October 2013) clarifies part styles, dimensional limits, ordering conventions and terminology used in the original EN 140401-802 standard. It is intended for manufacturers, test laboratories, procurement and design teams working with rectangular SMD film resistors.

Key topics and requirements

• Styles and dimensions: The amendment replaces Table 1 to define standard rectangular styles and their dimensional ranges (length, width, height), termination and mass for styles such as:
  • RR1005M (RR0402)
  • RR1608M (RR0603)
  • RR2012M (RR0805)
  • RR3216M (RR1206)
  • RR5025M (RR2010) Termination width and film thickness ranges are specified (T thickness 0.005 mm to 0.05 mm).
• Stability classes: Applies to stability classes 1 and 2 (resistor stability classification in production and design).
• Ordering and coding:
  • Use of the RKMG code system (per EN 60062) for resistance values is specified (four-character RKMG codes; no spaces allowed in electronic ordering).
  • Clarifies that ordering information for electronic order processing shall not contain spaces.
• Terminology and certification:
  • Replaces older references to National Supervising Inspectorate (NSI) with IECQ Certification Body (IECQ CB).
  • Notes on failure rate notation (Version E / “E0” for Version A) and other editorial corrections to naming (EN140401-802).
• Editorial and technical corrections: Several style-code name normalizations (e.g., removing spaces in style codes) and table corrections (RR3216M replacement) are included.

Applications and who uses it

• Resistor manufacturers - to ensure product dimensions, terminations and coding meet European detail specification for low-power film SMD resistors.
• Electronics OEMs and PCB designers - to select components that conform to standard dimensions and stability classes for automated assembly and reliability targets.
• Procurement and distribution - for correct RKMG coding and electronic ordering conventions to avoid errors in part data exchange.
• Test houses and conformity assessors - to reference the precise dimensional, marking and certification expectations when verifying compliance.

Related standards

• EN 60062 - RKMG code system for resistance value coding (referenced for resistance value notation).
• IECQ 01 - IEC Quality Assessment System for Electronic Components (reference for IECQ Certification Body terminology).
