These planar packages yield space saving, 10W/in2 power densities that require over 50% less board space than other radial packages. Convection cooling is maxi- mized by the planar package configuration which dissipates heat well above board level. Ohmite’s power chip resis- tors have a 125% higher oper- ating temperature range than competitive product of similar design. High temperature solder and in-process plat- ing keep terminations secure under self-heating effects by preventing re-flow from full power operation. Flexible packaging schemes make these resistors ideal for power supplies, audio ampli- fiers, video fly-back, and other power control applications.
