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). Ohmite’s 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 (http://www.ohmite. inductance and capacitance. The element provides com/cat/sink_cp4.pdf) is an example of properly stable performance in addition to high wattage and designed heat sink. The TAP800 rounds out 600 pulse loading capability. watt (TAP600) and 1000 watt (TAP1000) prod- • Contacts allow for easy load connecting with M4 or uct offerings. Applications include variable speed M5 screws (not included). drives, power supplies, robotics, motor control, con- • Materials meet the requirements of UL94-V0 trol devices, and other power designs. chArAcTeriSTicS Resistance Values 1Ω to 10KΩ Typical Results Resistance Tolerance ±5% to ±10% Test Method ∆R Temperature Coefficient ±150ppm/°C (others upon request) Short time 1,000 W/10sec 0.4% Maximum Working 5,000V DC, higher voltage on request, not exceeding overload Voltage max. power Humidity 56 days/40°C/95% 0.25% Short Time Overload 1,200W at 70°C for 10sec., ∆R=0.4% max.

This value can be reached by using thermal transfer compound with a heat conduc- tivity of 1W/mK. The flatness of the cooling plate must be better than 0.05mm overall. The roughness of the (continued) surface should not exceed 6.4µm. 142 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • info@ohmite.com
