Vishay Intertechnology, Inc. Chassis Mount Resistors FSOT4009E2K500KE

The FSOT4009E2K500KE is a chassis mount wirewound resistor from Lingto Electronic Limited, designed for industrial power applications. It has a power rating of 40 watts at 25 °C and a resistance value of 2.5 kΩ with a tolerance of ±10%. The resistor features a high-temperature silicon coating and is suitable for high-density packaging, allowing for efficient heat dissipation due to its mounting hardware, which also acts as a heat sink. It can withstand high vibrations without loosening and operates within a temperature range of -55 °C to +350 °C. The dielectric withstanding voltage is rated at 1000 V AC, ensuring reliability in various applications. The resistor is constructed with a copper-nickel alloy element and a ceramic core, providing durability and stability under thermal stress.
