By reducing the temperature rise of component hot spots, this high power density component can conserve printed circuit board (PCB) area and improve reliability. The TFHP series thin film high power chip resistors are developed for precision power supplies, power amplifiers, and process control applications, which all benefit from carefully designed element-to-terminal increased heat transfer.
Nick Atkinson, Senior Product Line Manager, TT Electronics, said: “The unique values offered by these resistors allow designers to reduce component size, minimize temperature rise, and increase reliability in high-power analog circuit designs.”
Building on TT’s expertise in power chip resistors designed to meet stringent thermal management goals, the new TFHP series offers 2W in the 1206 chip size and 6W in the 2512 chip size. Additionally, the TFHP features large area terminations for improved thermal contact with the PCB. These high power resistors offer better accuracy than thick film alternatives, offer 0.1% tolerance, 25ppm/°C TCR, reduce self-heating and improve linearity.
