Automotive Grade Anti-Surge Wire wound MELF Resistors (SWM) is applied in high pulse load applications such as in-rush current protection for power capacitors, motor start-up protection, battery cells balancing resistor , etc. so to prevent hazard of circuit damage caused by surge energy.

Automotive Grade Anti-Surge Wire wound MELF Resistor (SWM) features power rating from 1W to 4W,  resistances range from 1 ohm to 1.2K ohm, and tolerance at ±1%、±2% and ±5%.  SWM is widely working temperature between -55℃ ~ +200℃, very suitable for applications such as Industrial Automation、 electric vehicle and renewable energy storage. Anti-sulfur and AEC-Q200 certificated. RoHS and REACH compliant.

FIRSTOHM is able to design wire wound resistors according to customer's requirements with high quality and reliability since 1969, manufacture in TAIWAN and ISO9001/ISO14001 certificated.
