DIN EN 140401-802
Detail specification: Fixed low power film SMD resistors - Rectangular - Stability classes 1; 2; German version EN 140401-802:2007 + A1:2010 + A2:2013 + A3:2017
Bauartspezifikation: SMD Schicht-Festwiderstände niedriger Belastbarkeit - Rechteckig - Stabilitätsklassen 1; 2; Deutsche Fassung EN 140401-802:2007 + A1:2010 + A2:2013 + A3:2017
Overview
The detail specification describes chip-layer fixed low power resistors with a rectangular base for surface mounting of type RR; these are ceramic carriers with a protected, insulated resistor layer (thick film) and solder connections. The EZ assessment level, version A with 100% testing, version E with failure rate level and 100% testing and stability classes 1 and 2 are explained. The standard differs from DIN EN 140401-802:2014-09 as follows: specification of the standard products according to this detail specification to be manufactured with lead-free connections and determination of the optional special products according to this detail specification with leaded connection metallization in 1.1, Table 1, and 1.9.4; introduction of a new additional mark in the ordering information for special products with leaded connection metallization while retaining the specified ordering information for standard products in 1.9.4; revision of the test conditions and the test plan to differentiate between standard products and special products in 1.8.1 and Annex A, Table A.1 Revision of the application information on the soldering processes to differentiate between standard products and special products in 1.10.3. The responsible committee is DKE/GK 613 "Widerstände" ("Resistors") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
