Resistors with the Tetrinox resistance system solve the reliability problems related to other low TC precision resistor technologies. The robust construction of Caddock's Type TK Resistors provides reliable operation even in harsh temperature cycling and/or power cycling environments. Type TK Low TC Precision Radial-Lead Film Resistors provide a combination of performance advantages never before available in a resistive component: /RZ7HPSHUDWXUH&RHIFLHQW - better than 5 ppm/C, 10 ppm/C, or 20 ppm/C over the entire temperature range from -55C to +125C!

Tetrinox provides a wide range of resistivities, with the higher resistivities capable of producing resistance values up to 100 times higher than other ultra-low TC resistors in a similar size component. The essentially linear TC is well within 10 ppm/C over the entire temperature UDQJHIURP&WR&%\XVLQJ TK resistors engineers can design high precision circuits with lower current drain and lower power requirements.
