The TF656 series from Caddock are low TCR ultra-precision film resistors, with a resistance range from 10.01MΩ to 125MΩ. These resistors have a tolerance range from ±0.25% to ±1.0%. The TCR values available are ±5 ppm/°C (between -15°C and +105°C), ±10 ppm/°C (between -15°C and +105°C) and ±15 ppm/°C (between -15°C and +105°C). The Caddock TF656 series is available with either radial or axial tinned copper leads, it offers long term stability and is constructed using the Tetrinox® resistance technology.
