Product Overview

Caddock's Type TK Low TC Precision Radial-Lead Film Resistors, featuring the proprietary Tetrinox resistance system, are engineered to overcome reliability challenges associated with other low TC precision resistor technologies. These resistors offer exceptional performance in harsh temperature cycling and power cycling environments. Key advantages include a low temperature coefficient (TC) of 5 ppm/C, 10 ppm/C, or 20 ppm/C over a wide temperature range, long-term absolute stability, an extended resistance range from 1 Kohm to 10 Megohm, and precision tolerances including 0.1% as standard. Their robust construction, small size, and non-inductive performance make them ideal for high-frequency circuits and high-density packaging in commercial and industrial applications. Caddock does not recommend these resistors for applications due to the matte tin lead finish.
