Vishay Intertechnology, Inc. RES 680 OHM 10W 1% AXIAL LUGS RER65F6800MCSL

The RER65F6800MCSL 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 has a power rating of 10 watts at 25 °C and a resistance value of 680 ohms with a tolerance of ±1%. The resistor is constructed using non-inductive styles with Ayrton-Perry winding, minimizing reactive components. It operates 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. This component is suitable for applications requiring high reliability and performance under extreme conditions, making it a viable option for engineers looking for robust resistive solutions in demanding environments.
