Vishay Intertechnology, Inc. RES 5.11K OHM 30W 1% AXIAL LUGS RER75F5111PCSL

The RER75F5111PCSL 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 characterized by complete welded construction and non-inductive styles manufactured with Ayrton-Perry winding, which minimizes reactive components. With a power rating of 30 watts at 25 ¬8C, it has a resistance value of 5.11 kOc and a tolerance of ¬±1%. The operating temperature range is from -55 ¬8C to +250 ¬8C, making it suitable for a wide variety of environments. The resistor also boasts high insulation resistance of 10,000 MOc minimum when dry and 1,000 MOc minimum after moisture testing. This component is designed to mount on a chassis, utilizing the heat-sink effect for improved thermal management. It is constructed with a copper-nickel or nickel-chrome alloy element, depending on the resistance value, and features a ceramic, steatite, or alumina core. The encapsulant is made of silicone, and the housing is aluminum with a hard anodic coating, ensuring durability and reliability in demanding applications.
