The chips perform well over a wide frequency range, exhibiting low VSWR response from DC to 20 Ghz and higher. Solderable terminations allow the chips to be reflowed or hand soldered into microwave circuits easily while maintaining excellent return loss characteristics. Parasitic reactance is very low for these chips with capacitance being typically less than 0.1 pF. 50, 75,100, 200 ohms 0.1,1, 2, 5 % 50 milliwatts DC to 20 GHz 25, 50, 100 ppm/ C 0.03 % 0.03 % 0.03 % 0.03 % 0.05 % 0.05 % Thermal Shock Low Temperature Operation Short Time Overload Resistance to Bonding Exposure Moisture Resistance High Temperature Exposure * Typical percent resistance change -test methods and actual specification limits are in accordance with Mil-PRF-55342.

The last digit specifies the number of zeros to add. The letter "R" is used to represent the decimal for fractional ohmic values. 1.9 Thin film 0502 high frequency chip resistors are also available in other terminations styles and material finishes for attachment to circuit boards by soldering, bonding, or epoxy mounting. High power chip designs on BeO can be provided for increased heat dissipation. Custom chip designs are available to provide optimum solutions for specific high frequency applications. TYPICAL LIFE PERFORMANCE RESISTANCE VALUE 2.0 VSWR ENVIRONMENTAL PERFORMANCE* Parts are solder mounted on Fr4 board and tested at 70C. Power is applied for 90 minutes on and 30 minutes off at a rate that achieves a film temperature 30C above ambient. * Tight tolerance and low TCR availability The frequency response data plotted below shows an example of VSWR obtained for 50 ohm resistors tested (resistor element down) in pressure contact fixtures. Data for chips which are solder attached to matched circuit traces may exhibit even better performance.
