Technical content

Using one compact radial-lead resistor package can speed assembly procedures, simplify procurement, and simplify inventory. By reducing the wide variety of sizes and types of axial-lead resistors to a single compact radial-lead resistor package with advanced performance ratings, procurement and inventory can be simplified. The radial leads do not require additional bending prior to insertion, and the standard lead spacing can reduce the time required for assembly.

Recommended use: The Type MK resistors that are shown on this data sheet are recommended by Caddock for use in commercial and industrial applications. These RoHS resistors have pure matte tin (Sn) lead finish optimized for use in commercial and industrial applications. Presently, most military applications either prohibit the use of a matte tin lead finish or are trending toward this prohibition. Therefore, Caddock does not recommend and does not support the Type MK Resistors that are shown on this data sheet for use in military applications. Any use of this product in a military program, against this recommended limitation of use, must be completely supported by the customer program design activity and component engineering activity based on the complete evaluation and testing by these activities, there will be no support provided by Caddock for the military use. In this case, a military customer drawing must clearly specify the lead material, lead finish, and the military customer’s responsibility for use. Page 1 of 2 Non-Inductive with Expanded Resistance Range — 1 ohm to 100 Megohms Type MK Precision Power Film Radial-Lead Resistors provide high density packaging in circuit board applications. These resistors are available in two compact rectangular package configurations with standard lead spacings. Type MK Precision Power Radial-Lead Film Resistors cover the entire resistance range from 1 ohm to 100 Megohms, with a standard tolerance of 1%. Constructed with Caddock's Micronox ® resistance films fired onto a solid ceramic substrate, Type MK Precision Film Resistors combine all of these outstanding advantages:

  • ±1% Resistance Tolerance is Standard - tolerances to ±0.1% are available on special order.
  • Operating Temperature - from -40°C to +150°C.
  • Power Ratings at +85°C and at +125°C.
  • Temperature Coefficient is ≤ 50 ppm/°C from 5 ohms to 5 Megohms and ≤ 80 ppm/°C up to

100 Megohms - referenced to +25°C with the ∆R taken

at -15°C and +105°C.

  • Extended Life Stability is typically better than 0.1% per 1,000 Hours.
  • Caddock's Non-Inductive Performance - provides faster settling times and minimum distortion in all types of higher frequency circuits. This combination of performance features in a compact radial-lead resistor package can simplify engineering, inventory, and production: Selecting one compact radial- lead resistor package can simplify board layouts. With the exceptionally wide range of resistance values that are available in each model of Type MK Precision Power Film Radial-Lead Resistors, circuits can now be designed for greater packaging densities without the need for leaving extra space where resistor value changes can require larger resistors or non-uniform lead spacings.
