Vishay Intertechnology, Inc. RES 10.9 OHM 20W 1% AXIAL LUGS RER70F10R9RCSL

The RER70F10R9RCSL 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 utilizes a complete welded construction and non-inductive styles manufactured with Ayrton-Perry winding to minimize reactive components. With a power rating of 20 watts at 25 ¬8C, the RER70F10R9RCSL has a resistance value of 10.9 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 a high insulation resistance of 10,000 MOc minimum when dry, and 1,000 MOc minimum after moisture testing. This component is suitable for applications requiring high reliability and performance under extreme conditions, making it a viable choice for engineers looking for robust resistive solutions in demanding environments.
