ODIOF Series Little DemonC Carbon Composition Molded 5% & 10% Tolerance

Category: Electronics, Ohmite Manufacturing Co, Resistors

Overview

The ODIOF Series, also known as Little Demon^C, is a range of carbon composition molded resistors. These resistors are recognized for their robustness and reliability and are constructed through a molding process that integrates the terminals, insulation, and resistive element. Ohmite’s Little Demon^C is comparable to military-standard types, specifically Mil-R-11 Type RCO7, RC20, and RC32. The series is available in E24 and E12 values, with the latter for resistances above 100KΩ. The resistors in the ODIOF Series are designed to perform under high surge conditions, offering low noise, quick heat dissipation, and high temperature stability.

Features and Benefits

Molded Insulation: High dielectric strength due to the rugged construction of the device.
Surge Capabilities: Designed for high surge conditions without compromising reliability.
Durability: The series features a durable coating that is resistant to abrasions and chipping, ensuring legible color codes even after extensive use.
Compatibility: The series can be utilized as alternatives to ‘Mil’ spec RCO7, RC20, and RC32 types.

Specifications and Characteristics

Series Specifications: Within the datasheet, two varieties are listed – OD and OF. The OD type has a wattage rating of 0.25 watts, a resistance range from 2.29Ω to 5.6MΩ, with tolerances at ±5% for resistances below 100KΩ and ±10% above 100KΩ. The OF type has a wattage rating of 0.50 watts, a resistance range from 2.29Ω to 20MΩ, with the same tolerance thresholds as the OD type. Additionally, maximum voltage ratings are indicated as 250VAC and 500VAC for OD type and 350VAC and 700VAC for OF type.
Terminals: Solder-coated copper for robust connections.
Body: Molded Phenolic construction ensuring the device’s structural integrity.
Tolerance: Standard tolerances are set at ±5% for resistances below 100KΩ and ±10% for resistances above 100KΩ.
Derating: The resistors in the series have a linear derating from 100% at +70°C down to 0% at 130°C, indicating their performance in varying temperature conditions.
Single Pulse Power Capacity: The data on single pulse power capacity indicate the resistor’s ability to handle power surges of different durations.

Dimensions

Specifications of physical dimensions are listed for both OD and OF versions of the series with detailed measurements on length, diameter, and lead diameter, ensuring compatibility with various applications and ease of integration into circuit designs.
