Ohmite’s Little Demons are small, reliable carbon

composition resistors with exceptional strength.

They are made tough by a molding process that

combines the terminals, insulation and resistive ele-

ment into an integrated unit. Along with their small

size, Little Demons perform with low noise, dissipate

heat rapidly and offer high temperature stability.

Color codes are readable even after prolonged use

thanks to a very durable coating that resists abra-

sions and chipping normally associated with auto-

matic insertion equipment.
