Enamelled Wirewound Power Resistors Axial Leads

As a result of more than 50 years of experience and

continuous improvements the RWM Series of resistors

features proven reliability in AC or DC applications.

The high quality of the RWM resides mainly in the use of a

proprietary Vishay Sfernice enamel fired at high temperature

and free from any compound liable to corrode the resistive

wire.

FEATURES

• High dissipation up to 30 W (25 °C)

• Fire proof

• Excellent endurance typical drift ± 1.5 % after

1000 h

• Conformal vitreous enamel

• All welded construction

• Low ohmic values 0.1

 available

• Termination: Sn/Ag/Cu

• Material categorization: For definitions of compliance

The performance of this series of professional resistors fully



meets the requirements of the following specifications:



- NF C 83-210-001



- CECC 40201-001
