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 - better than, ppm/ C, or ppm/ C over the entire temperature range from -55 C to +5 C! Long-Term bsolute Stability - typically better than ±.5% per, hours of operation. Extended Range - from K ohm to Megohm. Precision s - ±.% is standard, and tolerances of ±% and ±.5% are available. Wide Operating Range - from -55 C to +75 C. Small Size - with four miniature rectangular cases for maximum packaging density and minimum mounting area. High Power Density - with power ratings of. Watt and.3 Watt in molded cases, the largest of which is a standard CK6 package. (Photos show resistors full size) 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. ecause 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. uilding on over 3 years of experience with our unique complex oxide technology, Caddock has perfected the Tetrinox resistance system - the first high resistance system to provide a TC that is well within ppm/ C and that is also essentially linear over the entire temperature range from -55 C to +5 C. The exceptional performance of Type TK resistors can achieve improvements in many circuit applications: Low TC "Matched-Pair" Dividers can be ssembled Without Pre-Selection of Resistors. n important application for Type TK resistors is in "matched-pair" voltage dividers where the low temperature coefficient provides ratio tracking of less than ppm/ C without resistor pre-selection or special testing. With factory selection, Type TK resistor pairs can be matched to within ppm/ C. Extended Range Reduces Power Requirements ecause the Type TK resistors provide resistance values as high as Megohms - values that are up to times higher than other types of ultra-low TC resistors - engineers can now design precision circuits with lower current drain and lower power requirements.

Utilizing Caddock proprietary resistance film systems, the Type USF resistors provide the Lowest TC with the Widest Range and the Highest Ratings available in the industry. TEL: FX: Page of Range 5 ohm to 5 Megohm. - C to +85 C, referenced to +5 C Series ZERO Nominal TC Maximum bsolute TC 3 Series ZERO Nominal TC Maximum bsolute TC : ±.% or ±.%. Specific standard resistance values are available that are most commonly required in high accuracy analog design. These values were selected and optimized for produceability and performance. 3 Series matched pairs are available with ratio TC as tight as.. Contact pplications Engineering. Ceramic package provides cool operation. Type USF Ultra-Stable Resistors are offered in standard resistance values that are most commonly used in precision analog design. These standard resistance values can be used in precise amplifier gain setting, precise resistor bridge circuits, precise transducer sense circuits, and precise voltage dividers with up to 5 volt input voltage. Extremely Low Power ( ): Type USF resistors are constructed with an aluminum oxide ceramic sandwich which provides great thermal conductivity. The ceramic sandwich package very effectively minimizes the power coefficient drift. Power coefficient is the resistance drift due to temperature rise in the element caused by the power (wattage) dissipation in the resistor where the selfheating temperature rise of the resistor element results in TC drift (temp. rise in C, times the temperature coefficient of the resistor). In the USF package, heat is pulled away from the resistance material efficiently by this ceramic sandwich package construction. Plastic molded Low TC foil resistors cannot provide this outstanding benefit since the plastic impedes the flow of heat, causing greater temperature rise at the resistor element and greater self-heating related resistance drift due to power dissipation. The USF Series resistors provide a new level of performance with near ZERO TC, very low power coefficient, wide resistance range, and higher voltage ratings than is offered by other resistor technologies. Type USF Series Ultra-Stable Resistors Constructed with two selected USF 3 Series Resistors bonded back to back to achieve outstanding low bsolute performance. The resistors are to be connected in parallel on the circuit board.

For lab grade applications which require higher voltage ratings (up to, volts) and power ratings (up to.75 Watt), we recommend Caddock's Type TF Low TC Ultra-Precision Film Resistors. The performance features of the Type TN Lab Grade Low TC Precision Film Resistors are: Low - 5,, or ppm/ C. Ultra-Precision - s from ±.5% to ±%. Range - from K to Meg. Non-Inductive Design.

11 TEL: FX: Type USVD and Type HVD Ultra-Precision Dividers - 45 Volts to 5 KV Type USVD Ultra-Precision Dividers have the very highest precision available in voltage dividers in the range of 45 Volts DC up to Volts DC. These dividers are formed by bonding together two selected Type USF Ultra-Precision Resistors. The precise selection of these high performance resistors, which form the voltage dividers, makes possible the outstanding voltage division performance. Ratio as tight as.% and Ratio TC of ppm/ C.
