OD/OF Series Little Demon® Carbon Composition Molded 10% Tolerance F e at u r e s • Molded insulation for high dielectric strength • Rugged construction • High surge capabilities • Comparable to “Mil” RC07, RC20, and RC32 types • OD/OF Series available in E12 values • 5% Tolernace Discontinued August 2021 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 element 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 abrasions and chipping normally associated with automatic insertion equipment.

Inventory should always be used on a first-in-first-out basis. 75mm ±5 3mm 60.4mm±1 60.4mm ±1 resistor use guidelines 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 resistors are sorted for 10% and 20% tolerance values. Carbon composition resistors are able to withstand larger short-term pulses and higher voltages than film resistors and are virtually impervious to ESD events (Electro-static discharge). 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 product is stored properly the resistance shift during the soldering operation will be minimal, less than 2% or 3%. Carbon composition resistors are highly hygroscopic and changes in resistance value can occur if too much moisture is absorbed. For this reason, it is recommended not to use water or water-soluble solvents to clean these components. Alcohol or hydrocarbon solvents are recommended for rinsing. bake procedure and Cautions A. Heat Treatment 110°C ±10°C 15 hours B. Frequency of heat treatment 1 time only C. Solder heat test after treatment Solder Dip Type Temp. Time Evaluation OD 300°C 3 sec within ±3% OF 350°C 3 sec within ±3% *Depth of Immersion: 4mm from the resistor body D. Cautions Solderability: may be affected due to oxidization of lead wire Resistance value: some units may not completely recover to original value. Soldering heat: some treated product may have substantial resistance change during soldering operation. It is recommended that parts be tested to evaluate soldering heat effects. Solder should not come in contact within 4mm of resistor body as this may cause a significant shift in resistance value due to high heat exposure.
