OD/OF/OA Series
Little Demon® Carbon Composition Molded
OD/OF Series (5% Tol.) OA Series (10%)
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.

Storage: Ohmite recommends storing carbon composition
All resistors are packaged in sealed poly bags with desiccant
to maintain a consistent humidity during storage. If parts are
removed from the protective plastic bag they should be used
as soon as possible or resealed in the plastic bag.

Carbon composition resistors are manufactured by extruding
a blend of carbon and organic binders inside a phenolic outer
body. The extrusion is cut to length, leads inserted, cured,
and marked to form a finished resistor. The carbon and binder
mixture is adjusted to produce different resistance values. The
resistorsꢀareꢀsortedꢀforꢀ5%,ꢀ10%,ꢀandꢀ20%ꢀtoleranceꢀvalues.
Carbon composition resistors are able to withstand larger
short-term pulses and higher voltages than film resistors and
areꢀvirtuallyꢀimperviousꢀtoꢀESDꢀeventsꢀ(Electro-staticꢀdis-
charge). Carbon composition resistors are also sensitive to
moisture and, therefore, storage recommendations should be
adhered to. Generally, any moisture absorbed during storage
will be "baked out" during the soldering operation. If the prod-
uct is stored properly the resistance shift during the soldering
operationꢀwillꢀbeꢀminimal,ꢀlessꢀthanꢀ2%ꢀorꢀ3%.
Carbon composition resistors are highly hygroscopic and
changes in resistance value can occur if too much moisture is
absorbed.ꢀForꢀthisꢀreason,ꢀitꢀisꢀrecommendedꢀnotꢀtoꢀuseꢀwaterꢀ
or water-soluble solvents to clean these components. Alcohol
or hydrocarbon solvents are recommended for rinsing.
