Vishay Intertechnology, Inc. Chassis Mount Resistors RER45F39R0RC02

The RER45F39R0RC02 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 has a power rating of 10 watts at 25 ¬8C and a resistance value of 39 ohms with a tolerance of ¬±1%. This model is constructed using non-inductive styles with Ayrton-Perry winding, which minimizes reactive components. It is suitable for applications requiring high reliability and can operate within a temperature range of -55 ¬8C to +250 ¬8C. The resistor also meets stringent performance criteria, including low temperature operation, short time overload, and moisture resistance, ensuring durability in demanding environments. Engineers considering this resistor should note its specifications for insulation resistance, maximum working voltage, and solderability, which align with military standards. The RER45F39R0RC02 is an appropriate choice for projects that require robust performance and reliability in challenging conditions.
