Surge Resistant MELF Resistor - SRM
Special conductive thin film resistors similar to CMA0204 / CMB0207
The Surge Resistant MELF Resistor features a power rating from 0.25W to 3W, with a resistance range from 0.1Ω to 2.2MΩ. It has the advantages of tight tolerance compared to other branded wire wound resistors, with ±1%~±5% tolerances, and maximum permissible surge voltage up to 10KV. It is equipped with higher levels of performance regarding inrush current or surge damage from the environment. It is AEC-Q200 certified and anti-sulfur. It has an SMD structure and the sizes are the same as flat chip resistors. It has been tested and certified according to DIN EN IEC 62368-1 (VDE 0868-1):2021-05 Anhang/Annex G.10; EN IEC 62368-1:2020+A11:2020 Anhang/Annex G.10 (except SRM204 type) with VDE license number 40043961 and VDE license number 40054118.
