Heater Non-Flammable Resistor High Precision Cement Wirewound

Non-Flammable Heater High Precision Cement Wirewound Resistors

Structure:

1.ZENITHSUN 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.Rated Power :5W
4.Strong Impact Resistance,high Insulation,special for frequency converter server.
5.ZENITHSUN Cement resistor is widely used in various products,which is the most basic electronic component of electronics, electrical appliances, equipment and information products.


Features:
1.Excellent stability in high temperature,resistant to humidity and shock with economic price.
2.Best suitable for heat dissipation and small linear temperature coefficient,can be PCB mounted.
3.Non Flammable Construction & Low Inductance type available.
4.ZENITHSUN is equipped to design and produce custom components to meet many design and reliability demands.
5.Contact us with your specific needs.
6.Conforms to the ROHS standard and the LEAD-FREE non-lead standard.
