Type TK Low TC Precision Radial-Lead 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:

Low Temperature Coefficient - better than 5 ppmrc.

10 ppm/°C, or 20 ppm/°C over the entire temperature range

from -55°C to +125°C!

Extended Resistance Range - fcjj gin eeb ebb from 1 K ohm to 10 Megohm. C$3 t§M ¡S3 Bfcfl

Precision Tolerances - ±0.1% is and ±0.05% are available.

Wide Operating Temperature

Range - from -55"C to +175°C. Small Size - with four miniature rectangular cases for maximum packaging density and minimum mounting area

High Power Density - with power ratings of 0.2 Watt and 0.3 Watt in molded cases, the largest of ■/■.■Inch is a standard CK0S package. Caddock's Non-lnc settling times and rr frequency circuits.

■.i. ixioe technology, Caddock has perfected the Tetrinox resistance system the ri.'sl high resistance system to provide a TC that is well within 10 ppm/°C and that is also essei-taly linear ever the enti/e temperature range from -55°C to +125X.

An important application for Type TK resistors is ^: "matched-pair" vollage dividers where the low 5 ppm/= temperature coefficie-l provides ra: 0 tracking of less the 10 pprn^C without resistor pre-selection or special testing.

High Density Packaging - the radial-lead mounting small rectangul packaging den: four models of exceptionally and mounting be standardized a larger number of designs.

Extended Resistance Range Reduces Power Requirements

Because the Type TK resistors provide resis:;irce velues as high as 10 Megohms - values that are up to 100 times higher than other types 0! ultra-low TC resistors - engineers can now design precision circuits with lower current dram and lower power requirements.
