WEET SQP Series Axial Cement Ceramic Resistor
Cement Ceramic 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.
It can withstand short-term overload, low noise, and the resistance value has not changed over the years.
Good explosion-proof performance and protection.

Product Drawing


Main Applications

WEET’s SQP Ceramic audio grade resistors are specially designed for applications requiring minimal samll board space, low head dissipation factor, and low cost.
These audiophile grade resistors are packaged in a nonflammable cement casing house and with an inorganic potting mix.
This combination provides resistance to the elements and high thermal conductivity.
With features like High Surge Capabilities and small sizes, the WEET cements wire wound resistor is perfect for all high power applications.
