1. INTRODUCTION
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-flameable and heat-resistant cement.
2. FEATURES
Heat and flame resistant!
Completely insulated character suitable for printed
circuit board.
For high resistance value, the winding core will
be replaced by metal oxide film cutting core (RS
type).
Non inductive type are available on request!
