Vishay Intertechnology, Inc. Chassis Mount Resistors RER65FR332RCSL

The RER65FR332RCSL 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. The resistor is constructed with complete welded assembly and is available in non-inductive styles, utilizing Ayrton-Perry winding to minimize reactive components. This specific model has a power rating of 10 watts at 25 ¬8C and a resistance value of 0.332 ohms with a tolerance of ¬±1%. It operates effectively within a temperature range of -55 ¬8C to +250 ¬8C and has a maximum working voltage determined by the formula (P x R)^{1/2}. The insulation resistance is rated at a minimum of 10,000 MOc when dry, decreasing to 1,000 MOc after moisture exposure. The resistor is suitable for applications requiring high reliability and stability under varying environmental conditions, making it a viable option for engineers looking for robust components in demanding settings.
