Introducing ultra-precision shunt resistors for high current applications - metal foil resistors with through-hole design.
Alpha Electronics is a brand of Vishay Precision Group (NYSE: VPG) that manufactures the most precise and stable resistors in the Vishay Foil Resistors product line. The stability of metal foil resistors, which possess the property of being "unchanging" with respect to temperature and time, is also applied as standard resistors. The 'PSB Series' utilizes a metal foil resistor element to achieve excellent resistance temperature characteristics. It is a four-terminal resistor that achieves high precision resistance value tolerances despite its ultra-low resistance. 【Specifications】 ■ Rated Power: 12W (when using a 40W heat sink) ■ Resistance Value Range: 0.001Ω to 1Ω ■ Resistance Value Tolerance: ±0.1%, ±0.5%, ±1.0% ■ TCR: 0±5ppm/℃, 0±15ppm/℃ *For more details, please refer to the PDF document or feel free to contact us.
