15W R75 Low Inductive Resistor Auto Ceramic Cement Wire Wound
15W R75 Low-inductive Auto Ceramic Cement Wirewound Resistors
Structure:
1.ZENITHSUN Charging resistor is ceramic rod with the resistance winding wire (the voltage-equalizing resistor is made of metal oxide film resistor core,instead of wire wound resistor core),put the wire wound resistance core into different sizes and shapes ceramic shells,sealed with special incombustible heat-resistant cement electronic filler,by natural drying in the shade and baking at high temperature.
2.For high resistance value,wires are replaced by metal oxide films.
3.Charging resistor is designed to charge the energy storage capacitor slowly when the frequency converter is just powered on,which is also called buffer resistor.
4.Power Range: 15W;
5.Strong Impact Resistance,High Insulation,Special for frequency converter server.
Features:
1.Small size,resistant to vibration,humidity and heat,good dissipation,low noise and no annual shift in resistance value,low price
2.ZENITHSUN is equipped to design and produce custom components to meet many design and reliability demands.
3.Contact us with your specific needs.
4.Conforms to the ROHS standard and the LEAD-FREE non-lead standard.
