Vishay Intertechnology, Inc. Chassis Mount Resistors RER60F1750MCSL

The RER60F1750MCSL 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. The resistor is non-inductive, utilizing Ayrton-Perry winding to minimize reactive components, and is capable of mounting directly onto a chassis to enhance heat dissipation. This model has a power rating of 5 watts at 25 ¬8C and a resistance value of 175 ohms with a tolerance of ¬±1%. It operates effectively within a temperature range of -55 ¬8C to +250 ¬8C and has a high insulation resistance of 10,000 MOc minimum when dry. The construction includes a copper-nickel or nickel-chrome alloy element, a ceramic core, and an aluminum housing with a hard anodic coating, ensuring durability and reliability in demanding environments. Engineers considering this resistor should note its robust performance characteristics, including compliance with military specifications and its suitability for applications requiring high reliability.
