Type TK Low TC Precision Radial-Lead Film Resistors Page 1 of 2 RoHS Compliant -- TK200 Series and TK700 Series Resistors Low TC of 5 ppm/C or 10 ppm/C, Resistance Range from 1 Kohm to 1.5 Meg Low TC of 10 ppm/C or 20 ppm/C, Resistance Range from 1.51 Meg to 10 Meg 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: Low Temperature Coefficient - available in 5 ppm/C, 10 ppm/C, or 20 ppm/C over the entire temperature range from -40C to +125C, referenced to +25C. Long-Term Absolute Stability - typically better than 0.05% per 2,000 hours of operation. Extended Resistance Range - from 1 Kohm up to 10 Megohm. Precision Tolerance - 0.1% is standard, and tolerances of 1% and 0.05% are available. Type TK200 series and TK700 series Low TC Precision (Resistors shown full size) Radial Film Resistors utilize Caddocks long proven Tetrinox Wide Operating Temperature resistance system - the first high resistance system to Range - from -40C to +150C. provide a TC that is well within 10 ppm/C and that is also Small Size - with two miniature rectangular cases for essentially linear over the entire temperature range from maximum packaging density and minimum mounting area. -40C to +125C. High Power Density - molded cases with power ratings of Standard Part Number Includes: Standard resistance value 0.2 Watt and 0.3 Watt at +85C, the largest of the molded (listed below), standard tolerance of 0.1%, and standard cases is a standard CK06 package. temperature coefficient of 10 ppm/C. Caddock s Non-Inductive Performance - provides faster TK229 TK729 TK233 TK733 settling times and minimum distortion in all types of high 1.00 K 1.00 K 900 K 2.00 Meg frequency circuits. 2.00 K 2.00 K 4.00 Meg 1.00 Meg High Density Packaging - the radial-lead mounting and 4.00 K 4.00 K 5.00 Meg 2.00 Meg small rectangular case of the Type TK resistors permit high 5.00 K 5.00 K 9.00 Meg packaging densities in low profile circuitry. Because the 9.00 K 9.00 K 9.90 Meg four models of the Type TK resistors are available in an 10.0 K 10.0 K 10.0 Meg exceptionally wide range of resistance values, lead spacing 20.0 K 20.0 K and mounting space can be standardized in a larger 40.0 K 40.0 K number of designs. 50.0 K 50.0 K 90.0 K 90.0 K Recommended use: 100 K 100 K 200 K The Type TK resistors that are shown on this data sheet 200 K 400 K are recommended by Caddock for use in commercial and 400 K 500 K industrial applications. These resistors have pure matte 500 K 900 K tin (Sn) lead finish for use in commercial and industrial 1.00 Meg applications. Non-Standard Part Number Includes: Presently, military applications either prohibit the use of a matte tin lead finish or are trending toward this prohibition. Non-standard resistance value and/or non-standard tolerance Therefore, Caddock does not recommend and does not and/or non-standard TC.
