Vishay Intertechnology, Inc. RES 20 OHM 10W 1% AXIAL LUGS RER45F20R0RCSL

The RER45F20R0RCSL 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 10 watts at 25 ¬8C, the RER45F20R0RCSL has a resistance value of 20 ohms and 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 resistor also boasts high insulation resistance, rated at a minimum of 10,000 MOc when dry, and 1,000 MOc after moisture testing. This component is suitable for applications requiring robust performance under extreme conditions, making it a reliable choice for engineers in need of durable resistive solutions.
