Overview

EN 140401-801:2007/A1:2013 is a CENELEC amendment to the European detail specification for fixed low power film SMD resistors (rectangular). The amendment clarifies dimensional styles, updates stability class limits, refines ordering/coding rules and aligns certification terminology (NSI → IECQ Certification Body). This standard applies to rectangular SMD thin-film resistors in stability classes 0.1, 0.25, 0.5 and 1.

Key Topics

• Component styles and dimensions: Defines standard SMD style codes (RR1005M / RR0402, RR1608M / RR0603, RR2012M / RR0805, RR3216M / RR1206, RR5025M / RR2010) with length, width and height ranges, termination geometry and representative mass values. Termination thickness is specified in the range 0.005–0.05 mm.
• Stability class performance: Updates limits expressed as a percentage of resistance plus a fixed ohm term. Examples from the amendment:
  • Class 1: e.g. ±(1% R + 0.05 Ω)
  • Class 0.5: e.g. ±(0.5% R + 0.05 Ω)
  • Class 0.25: ±(0.25% R + 0.05 Ω)
  • Class 0.1: ±(0.1% R + 0.02 Ω)
• Ordering and coding: Requires electronic ordering strings without spaces and references the RKMG code system (resistance coding per EN 60062) for resistance value representation.
• Certification and quality language: Replaces references to National Supervising Inspectorate (NSI) with IECQ Certification Body (IECQ CB) and adds explanatory notes about IECQ rules.
• Editorial and technical corrections: Corrects style code spellings and table entries from the 2007 edition.

Applications

This standard is directly relevant for:

• Passive component manufacturers (design, production tolerances, marking, qualification)
• PCB designers and electronic OEMs specifying SMD resistors for precision analog and mixed-signal circuits
• Purchasing and supply chain for unambiguous ordering (RKMG codes, no-space order strings)
• Test laboratories and certification bodies applying performance and stability class verifications
• Standards and compliance teams ensuring national implementation of CENELEC requirements
