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.
