Vishay Intertechnology, Inc. Chassis Mount Resistors FSOT4009ER5000KE

The FSOT4009ER5000KE is a chassis mount wirewound resistor designed for industrial power applications. It has a power rating of 40 watts at 25 ¬8C and a resistance value of 0.5 ohms with a tolerance of ¬±10%. The resistor features a high-temperature silicone coating and is suitable for high-density packaging. It can withstand high vibrations without loosening, and its mounting hardware acts as a heat sink, enhancing heat dissipation and reducing derating of stacked units. The operating temperature range is from -55 ¬8C to +350 ¬8C, and it has a dielectric withstanding voltage of 1000 V AC. The resistor is constructed with a copper-nickel alloy element and a ceramic core, ensuring durability and reliability in demanding environments.
