Vishay Intertechnology, Inc. Chassis Mount Resistors RER55F5110PCSL

The RER55F5110PCSL 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 constructed with complete welded assembly and offers non-inductive styles manufactured using Ayrton-Perry winding, which minimizes reactive components. With a power rating of 30 watts at 25 °C, the RER55F5110PCSL has a resistance value of 511 ohms and a tolerance of ±1%. It operates effectively within a temperature range of -55 °C to +250 °C and has a maximum working voltage determined by the formula (P x R)^{1/2}. The insulation resistance is a minimum of 10,000 MΩ when dry and 1,000 MΩ after moisture testing. The resistor is suitable for applications requiring high reliability and performance under extreme conditions.
