500W Non Inductive High Power Carbon Film High Voltage Resistors
Features:
1.High-power frequency non-inductive carbon resistors have two types:RCF(High-power non-inductive carbon resistors and RCFG( High-power non-inductive voltage carbon resistor).
2.RCF and RCFG resistors'tubular tips coating with silver or gold as pole,low-inductance non-helical trimmed product.
3.Afford high power ,suitable for the application with large current as well as high frequency circuit.
4.RCF and RCFG resistors use special oxide film technology attached in the ceramic rod ,coated with glass glaze(to sure products'electric and mechanical characteristic.
Applications:
Widely used in high-voltage electrical instrument equipment,load resistor and bleeder resistor,switches power supply and module,high-power AC and DC motor control,staring and speed governing.
Advantages:
1.Manufacturing standard &customs design;
2.Sample orders are available;
3.Immediately Response,reply you for your inquiry in 24 hours;
