Ohmite’s Little Demons are

small, reliable carbon compo-

sition resistors with exceptional

strength. They are made tough

by a molding process that

combines the leads, insulation

and resistive element into an

integrated unit. Along with their

small size, Little Demons per-

form with low noise, dissipate

heat rapidly and offer high

temperature stability.

Color codes are read-

able even after prolonged use

thanks to a very durable coat-

ing that resists abrasions and

chipping normally associated

with automatic insertion equip-

ment.

FEATURES

• Molded insulation for high dielec-

tric strength.

• Rugged construction.

• Available in Resistor Cabinet

Assortments & 100 pc packs.

• High surge capabilities.

• Comparable to “Mil” RC07,

RC20, and RC32 types.
