The TK729 series, low TCR precision radial-lead film resistors from Caddock have a resistance range between 501KΩ and 2MΩ the low TCR of ±10 ppm/°C comes as standard between -40°C and +125°C (±20 ppm/°C is avaiailable on special order) and with a tolerance of ±0.1% as standard (with options for ±1.0% and ±0.05% on special order). The TK729 series uses Caddock’s Tetrinox® resistance system to solve the reliability problems related to other low TC precision resistor technologies, the robust construction provides reliable operation even in harsh temperature cycling and/or power cycling environments.
