Vishay Intertechnology, Inc. Chassis Mount Resistors RER65F2R05RC02

The RER65F2R05RC02 is a chassis mount wirewound resistor from Lingto Electronic Limited, designed for military applications and qualified to MIL-PRF-39009 standards. It features an aluminum heat sink housing and a molded construction that provides total environmental protection. This resistor is non-inductive, utilizing Ayrton-Perry winding to minimize reactive components, and is capable of mounting directly onto a chassis to leverage heat-sink effects. With a power rating of 10 watts at 25 °C, the resistor has a resistance value of 2.05 ohms and a tolerance of ±1%. It operates effectively within a temperature range of -55 °C to +250 °C and has a high insulation resistance of at least 10,000 MΩ when dry. The construction includes a copper-nickel or nickel-chrome alloy element, a ceramic core, and an aluminum housing with hard anodic coating, ensuring durability and reliability in demanding environments. Engineers considering this resistor should note its robust performance characteristics, including compliance with military standards and its suitability for applications requiring high reliability and environmental protection.
