Vishay Intertechnology, Inc. RES 464 OHM 20W 1% AXIAL LUGS RER50F4640RCSL

The RER50F4640RCSL is a chassis mount wirewound resistor designed for military applications, 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 20 watts at 25 ¬8C, the resistor has a resistance value of 464 ohms and a tolerance of ¬±1%. It operates effectively within a temperature range of -55 ¬8C to +250 ¬8C. The insulation resistance is a minimum of 10,000 MOc when dry, and 1,000 MOc after moisture testing. The resistor is suitable for applications requiring high reliability and stability under varying environmental conditions. Engineers considering this component should note its robust construction and military-grade specifications, making it suitable for demanding applications.
