Type ER/ERV Series

A tough silicone coated power

resistor. The coating and marking

are resistant to Trichloroethene VG,

Genklene LV Hot and Cold, Freon

TE, Arklone A, Flourosil E, Freon

TMS, Arklone L Hot and Cold and

Arklone F Hot. If the resistor is in

contact with the PCB the maximum

dissipation to avoid damage to the

PCB

may

be

ascertained

by

reference

to

the

hot

spot

temperature

graph.

Vertical

mounting style is available. The ER

series is suited to a wide range of

industrial, control, medical and

consumer applications.
