TAP800KR25E Ohmite

Rated power, watts TAP800 Series 800 Watt Heat Sinkable Planar FeATureS Electric support is high alumina content ceramic metallized on the bottom for ideal heat transfer and optimum discharge. Encapsulated with a special resin filled epoxy cas- ing with a large creepage distance to mass, large air distance between terminals, and a high insula- tion resistance (CTI 600). Ohmites TAP800 Series dissipates 800 watts of power when used with a liquid or air cooled heat Resistive element is specially designed for low sink system. The Ohmite CP4 (0.1770.216 (4.55.5mm) TAP800 Series 800 Watt Heat Sinkable Planar PulSe energy And Power curveS Typical rating for TAP800 with 2R and 10% tolerance 10,000 These energy values are reference values depending on ohmic value and used resistive paste, a variation in max. energy load capability is possible. Energy The power curve shows the max. possible power which can be applied 1,000 for a certain duration. Mounted with thermal compound Change in ohm value: 0.1% 100 (0.9 W/mK) on a water-cooled Power Pulse shape: e-function heatsink 10 Time between two pulses: 1 sec.
