RWM

Vishay Sfernice

Enamelled Wirewound Power Resistors

Axial Leads

FEATURES

•

High dissipation up to 30 W (25 °C)

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.

•

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

•

Compliant to RoHS Directive 2002/95/EC

The performance of this series of professional resistors fully

meets the requirements of the following specifications:

- NF C 83-210-001

- CECC 40201-001

OVERLOAD

Heavy overloads can be endured in the form of short pulses

< 0.1 s. Particular requirements should be submitted to

Vishay Sfernice, specifying peak voltage, cycle and

environmental conditions.

Group Mounting

In a still atmosphere, a distance between axes equal to five

times the resistor’s diameter is recommended.

Cabinet Mounting

•

Unventilated box: Dissipation should be reduced (see

RECOMMENDATIONS FOR USE

Since these components are high dissipation power

resistors, customers are advised to use a high melting point

solder.

For low ohmic values, the measurement becomes critical

and the connecting wires resistance is to be included. The

value is measured at 5 mm from the resistor body.

dimensional drawing).

•

Forced ventilation: If conditions are appropriate,

dissipation may be doubled or even trebled.

•

In any case: The surface temperature at the hottest point

should not exceed 450 °C.

These aspects should be considered by the end user.
