Our SMD resistor is mainly used in current Sensing/Overcurrent protection, New Energy Vehicles, Conventional Automotive Control Circuits, White Goods, Inverters, Switching Power Supplies, Mobile Phone Chargers, Electric Bike Chargers, Telecom Power Supply, Solar Power Controller, LED Power Controllers, etc. And it has many benefits, which mensioned below:
All-metal structure, high power density
All-metal construction, impact resistance, high temperature resistance
Lower resistance value and low power consumption
Electron beam welding, low temperature drift, high stability, lead-free, low thermal electromotive force
High accuracy: +1%; +5%
The inductor <5
ROHS, AEC-Q200,
Customized
Operating temperature: -65~17摄氏度
