SQM Datasheet, PDF (1/6 Pages) MERITEK ELECTRONICS CORPORATION – Cement Wirewound Resistors (Radial Type)

Cement Wirewound Resistors
(Radial Type)
SQM Series
FEATURES
 Heat and flame resistant
 The complete insulation characteristics are ideal for printed circuit board applications.
 For high resistance value, the winding core will be replaced by metal oxide film core (RS type).
 Non-inductive types are available on request.
 Tolerance: ±5% ±10%.
