26 Type MK Precision Power Film Radial-Lead Resistors Non-Inductive with New Expanded Resistance Range 1 Ohm to 100 Megohms Here are the precision radial lead resistors that provide high density packaging in circuit board applications. Available in three miniature rectangular package configurations with standard lead spacings, Type MK Precision Power Radial-Lead Film Resistors now cover the entire resistance range from 1 ohm to 100 Megohms. 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 -55C to +175C. Full Power Rating at +125C. * Temperature Coefficient is < 50 ppm/C from 5 ohms to 5 Megohms and < 80 ppm/C up to 100 Megohms - referenced to +25C with the AR taken at -15C and +105C. * 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 high frequency circuits. This combination of performance advantages in a small, standardized case can simplify many engineering and production problems: One size of Type MK resistor can replace many sizes of axial-lead resistors. This table of "RN" style axial-lead resistors shows the many sizes and power ratings that can be replaced with one of the three models of Type MK Precision Film Resistors within the maximum allowable voltage ratings.

The largest Type MK - rated at .75 watt - requires less board space than even the .05 watt RN50. The smallest Type MK - rated at .50 watt - provides power dissipation equal to the RN7O resistor. The RN7O resistor requires a mounting hole spacing of 1 inch and a side-to-side spacing of .25 inch, resulting in a total mounting area of .25 square inch - 10 times the area required for a .50 watt Type MK resistor! me 3789600 000035? 137 One standard resistor configuration can simplify board layouts. With the exceptionally wide range of resistance values that are available in each model of Type MK Precision Film Resistors, circuits can now be designed for maximum packaging densities without the need for leaving extra space where resistor value changes can require larger resistors or non-uniform lead spacings. Standardization of resistor size can speed assembly procedures and reduce procurement costs. The standardization of resistor size can pay additional dividends by simplifying assembly procedures. The radial leads do not require additional bending prior to insertion, and the standard lead spacing can reduce the time required for assembly. The combination of higher power ratings and smaller size can also lower procurement costs. By reducing the wide variety of sizes and types of axial-lead resistors to a single, standardized resistor type, unit prices can be lowered and inventory problems simplified.
