Vishay Intertechnology, Inc. Chassis Mount Resistors RER40F1300PC02

The RER40F1300PC02 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 5 watts at 25 °C and a resistance value of 130 ohms with a tolerance of ±1%. It operates effectively within a temperature range of -55 °C to +250 °C. The resistor's insulation resistance is a minimum of 10,000 MΩ when dry, and it meets solderability requirements as per ANSI J-STD-002. The construction includes a copper-nickel or nickel-chrome alloy element, a ceramic core, and an aluminum housing with hard anodic coating, ensuring durability and reliability in demanding environments. Engineers considering this resistor should note its robust specifications and military-grade qualifications, making it suitable for applications requiring high reliability and performance under extreme conditions.
