30W220R Low Inductance Wirewound Power Ceramic Cement Resistors
Structure:
1.ZENITHSUN Cement resistor is ceramic rod with the resistance
winding wire or a wire wound resistance core is formed on the glass
fiber,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.Voltage-equalizing resistor with leading out in the form of
circular end or a square end.
5.The main function of the voltage-equalizing resistor is to use
the voltage dividing principle to ensure that the voltage on each
capacitor is equal.
6.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.
