Cement resistors are made by winding the resistance wires on the alkaliless ceramic cores,then coated with noncorrosive, heat-proof and humidity-proof material. Cement type is the one with special flameproof cement stuffed in the ceramic case.
Construction of SQP type cement resistors:
Features:
1、Low cost, space saving
2、RoHS compliant with 100% lead free
3、Direct mounting on printed circuit board
4、Circuit board lock-in mounting tabs available
5、High performance for power required applications
6、 Operating ambient temperature: -55℃~+275℃
7、 Resistance tolerance:±1%、±2%、±5%、±10%
8、High power to size ratio, Special inorganic potting compound
9、Ceramic case provide high thermal conductivity in a fireproof package
10、 Good heat-durability, low temperature coefficient, low noise, high load power, high insulating capacity.
Material Specifications (SQ)
Core :High purity grade alumina ceramic rod.
