Surge Resistant MELF Resistor-SRM

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.

Fusible MELF Resistor-FM

Fusible MELF Resistor (FM) is an SMD-enabled structure with MELF 0207 size, featuring a power rating from 0.33W to 1W and a resistance range from 2.2 ohms to 10K ohms, which is better in heat dissipation than a chip resistor and stronger in mechanical structure to endure vibration and thermal shock. The fusible resistor is a special resistor made to protect every circuit.

Surge Safety Resistor-SSR

The Surge Safety Resistor (SSR series) features a power rating from 0.25W to 5W, with resistance ranging from 10 ohm to 330K ohm. Designed to replace carbon or ceramic composition resistors, the SSR series is a good choice for anti-surge applications such as fuel ignition systems, power charging/discharging circuits, and ECG cables to absorb harmful surge energy, thereby preventing the hazard of fire and circuit damage caused by surge energy with a flameproof coating. Products comply with RoHS requirements and do not contain substances of very high concern identified by the European Chemicals Agency.

Anti-Surge Wire Wound Resistors-SWA

The Anti-Surge Wirewound Resistor (SWA series) offers a power rating from 1W to 6W, with a resistance range from 100m ohm to 1.2K ohm. The enhanced weld spot is not broken by surge impact, and the alloy wire can absorb harmful surge energy, making it suitable for high surge applications such as rush current protection of power capacitors, motor start-up protection, car & motorcycle engine ignition, thereby preventing the hazard of circuit damage caused by surge energy.
