Overview

EN 140401-802:2007/A1:2010 is a European standard developed by the CENELEC (European Committee for Electrotechnical Standardization) for fixed low power film SMD (Surface-Mount Device) resistors of rectangular shape, specifically addressing stability classes 1 and 2. This document serves as a detail specification, focusing on technical requirements, performance limits, and quality assurance for SMD resistors used in various electronic applications. The standard is widely utilized by manufacturers, engineers, and quality control teams in the electronics industry to ensure component reliability and consistency.

Key Topics

• Scope of Standard: Provides specifications for fixed, low power film resistors intended for surface-mounting technology, with rectangular geometry and classified under stability classes 1 and 2.
• Stability Classes: Defines and distinguishes between stability classes 1 & 2, detailing allowed resistance change limits under various test conditions (such as climatic sequence, soldering heat, rapid temperature changes, endurance, overload, and vibration).
• Testing Requirements: Outlines key test procedures for environmental, mechanical, and endurance testing, referencing harmonized European and international methods, such as EN 60115-1 and EN 60068-2-20.
• Quality Assessment: Includes revised and up-to-date guidelines for quality assessment systems, inspection sampling plans, and test method selections (EN 61193-2).
• Amendment Highlights: Amendment A1 introduces clarified resistance change limits, revised test references, and updated bibliographic details, ensuring the specification remains current and relevant.

Applications

EN 140401-802:2007/A1:2010 is critical for the following sectors:

• Electronics Manufacturing: Used in specification sheets and procurement for SMD resistors in consumer electronics, industrial controls, automotive electronics, telecommunications, and instrumentation.
• Quality Assurance: Essential reference for QA/QC teams performing component reliability evaluation, inspection, and qualification of resistor suppliers.
• Product Design: Guides engineers in selecting appropriate SMD resistors for circuit designs requiring high reliability, tight tolerance, and defined stability characteristics.
• Testing Laboratories: Supports laboratories in conducting standardized resistance change testing, environmental simulations, and endurance evaluations according to defined limits and procedures.

Adherence to this standard helps ensure:

• Consistent product quality throughout supply chains
• Interchangeability and compatibility in electronic assemblies
• Reduced risk of early component failure, supporting overall system reliability
