WEET SQM Radial Cement Housed Ceramic Resistor

Cement resistors are manufactured by winding the ceramic rods with metal alloy resistance wire and put it in a fireproof ceramic box then concrete with non-flammable and heat-resistant cement.
Excellent heat resistance, low temperature coefficient of resistance and linear change.
Power Rating 70℃：2W，3W，5W，7W，10W，3WS，5WS，7WS，10WS
