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.
