Ohmite’s original Power Chip resistors are designed from our thick film on alumina substrate technology.
These planar packages yield space saving, 10W/ in2 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.
Ohmite’s power chip resistors have a 125% higher operating temperature range than competitive product of similar design.
High temperature solder and in-process plating 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 amplifiers, video fly-back, and other power control applications.
FEATURES • High-Temp Terminal Construction • Wide Resistance Range • Low Inductance (50nH-100nH) • High Power Density • Easy to install.
