Detailed Product Description

50W2.2 Ohm + 2.2 Ohm Low Inductance Dual 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.
7.Rated Power:10W-15W-20W-25W-30W-40W-60W-80W .

 

Features:
1.Small size,resistant to vibration,humidity and heat,good dissipation,low noise and no annual shift in resistance value,low price,withstand short time overload,the resistance value has no change over the years.
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.
