Type TK Low TC Precision Radial-Lead Film Resistors

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.

provide a combination of performance advantages never

before available in a resistive component:

•

Low TC of 5 ppm/°C, 10 ppm/°C, or 20 ppm/°C and Resistance Range from 1 Kohm to 10 Megs

Low Temperature Coefﬁcient - better than 5 ppm/°C,

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

from -55°C to +125°C!

Long-Term Absolute Stability - typically better than

±0.05% per 2,000 hours of operation.

Extended Resistance Range -

from 1 K ohm to 10 Megohm.

Precision Tolerances - ±0.1% is

standard, and tolerances of ±1%

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

which is a standard CK06 package.

Caddock's Non-Inductive Performance - provides faster

settling times and minimum distortion in all types of high

frequency circuits.

High Density Packaging - the radial-lead mounting and

small rectangular case of the Type TK resistors permit high

packaging densities in low proﬁle circuitry. Because the

four models of the Type TK resistors are available in an

exceptionally wide range of resistance values, lead spacing

and mounting space can

be standardized in

a larger number

of designs.

Extended Resistance Range Reduces Power Requirements

as high as 10 Megohms - values that are up to 100 times

higher than other types of ultra-low TC resistors - engineers

can now design precision circuits with lower current drain

and lower power requirements.
