Vishay Intertechnology, Inc. Chassis Mount Resistors RER65FR150MC02

The RER65FR150MC02 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 leverage the heat-sink effect. This model has a power rating of 10 watts at 25 °C and a resistance value of 0.15 ohms with a tolerance of ±1%. It operates effectively 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 rated at a minimum of 10,000 MΩ when dry, decreasing to 1,000 MΩ after moisture exposure. The resistor is constructed with a copper-nickel or nickel-chrome alloy element, depending on the resistance value, and features a ceramic, steatite, or alumina core. Engineers considering this resistor should note its robust construction and military-grade reliability, making it suitable for demanding applications where performance and durability are critical.
