Vishay Intertechnology, Inc. Res Wirewound 19.9 Ohm 1% 30W ¦50ppm/¦C 0.01% AXL Flange Card Pack RER55F19R9RC02

The RER55F19R9RC02 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 has a power rating of 30W at 25¬8C and operates within a resistance range of 1 to 4.99KOc with a tolerance of ¬±1%. The product is constructed with a complete welded design and non-inductive styles that utilize Ayrton-Perry winding to minimize reactive components. It is suitable for mounting on a chassis to leverage the heat-sink effect, enhancing thermal management. The operating temperature range is from -55¬8C to +250¬8C, ensuring reliability in extreme conditions. With a high insulation resistance of 10,000 MOc minimum when dry, and 1,000 MOc minimum after moisture testing, this resistor is built to withstand various environmental stresses. It meets solderability requirements as per ANSI J-STD-002, making it a robust choice for demanding applications.
