The RER40F1R27RCSL 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 non-inductive, utilizing Ayrton-Perry winding to minimize reactive components, and is capable of mounting directly onto a chassis to leverage the heat-sink effect. With a power rating of 5 watts at 25 °C, the resistor has a resistance value of 1.27 ohms and a tolerance of ±1%. It operates effectively within a temperature range of -55 °C to +250 °C. The insulation resistance is rated at a minimum of 10,000 MΩ when dry, and 1,000 MΩ after moisture testing. The construction includes a copper-nickel or nickel-chrome alloy element, a ceramic core, and stainless steel end caps, ensuring durability and reliability in demanding environments. Engineers considering this resistor should note its robust performance specifications, including low temperature operation, short time overload, and moisture resistance, making it suitable for various applications requiring high reliability.
