Vishay Intertechnology, Inc. Chassis Mount Resistors RER75FR402RC02

The RER75FR402RC02 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 using Ayrton-Perry winding to minimize reactive components. This model has a power rating of 30 watts at 25 ¬8C and a resistance value of 0.402 ohms with a tolerance of ¬±1%. It operates effectively within a temperature range of -55 ¬8C to +250 ¬8C and has a high insulation resistance of 10,000 MOc minimum when dry. The resistor is suitable for applications requiring high reliability and performance under extreme conditions, making it a viable choice for engineers looking for robust components in demanding environments.
