Cement resistor

SQP cement resistors are made by winding resistance wires around non-alkaline ceramic core,which is adde with a layer of heat and humidity resistant and non-corrosive protective material.The wire wound resistor is then placed in a square ceramic package sealed with special nonflammable heat-resistant cement. For high resistance value,wires are replaced by metal oxide films Small size,resistant to vibration,humidity and heat,good dissipation,low noise and no annual shift in resistance value,low price. Complete insulation suitable for printed circuit boards.
