The RER40F2800RC02 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 specific model has a power rating of 5 watts at 25 °C and a resistance value of 280 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 resistor also boasts a high insulation resistance of at least 10,000 MΩ when dry, ensuring reliable performance in various conditions. 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.
