TA Series Power Chip Thick Film on Alumina Substrate Ohmites original Power Chip resistors feature our thick film on alumina substrate technology. These 2 planar packages yield space saving, 10W/in power densities that require over 50% less board space than other radial packages. Convection cooling is maximized by the planar package configuration which dissipates heat well above board level. Ohmites power chip resistors have a 125% higher operating temperature range than competitive prod- FeATureS uct of similar design. High temperature solder and High-Temp Terminal Construction in-process plating keep terminations secure under Wide Resistance Range self-heating effects by preventing re-flow from full Low Inductance (50nH-100nH) power operation. Flexible packaging schemes make these resistors High Power Density ideal for power supplies, audio amplifiers, video fly- Easy to install. PC-mountable back, and other power control applications.
