Pleased follow these guidelines when designing TAP system: • Heats sink plate (base plate of the resistor) temperature must be monitored to establish proper de-rating. Best technique is to attach a thermocouple to the side of the base plate of the resistor. Temperature of plastic housing or heat sink cannot be used to establish rating of the resistor. Usage of laser thermometers should be avoided. • To obtain a power rating of 1000W or 2000W, the bottom case temp must not exceed 85°C. This can only be achieved if the thermal conduction to the heatsink Rth-cs<0.025°K/W. This value can be reached by using thermal transfer compound with a heat conductivity of 1W/mK. The flatness of the cooling plate must be better than 0.05mm overall. The roughness of the surface should not exceed 6.4µm. • Due to very high power density, only liquid cooled heat sinks are recommended for applications when >300W power rating is desired. • Properly designed heat sink should have more than 2 cooling pipes under the surface of the TAP resistor. The Hydroblok, a 4 pass aluminum heat sink (http://www.ohmite.com/ta1k0sink.html) is an example of properly designed heat sink. 0.689" (17.50mm) 1.308" (33.21mm) 1.622" (41.20mm) 3.000" (76.20mm) 1.308" (33.21mm) (same dimensions) 0.300" (7.62mm) 0.450" (11.43mm) 0.188" (4.76mm) 0.798" (20.26mm) o r d e r i n g i n f o r m at i o n RoHS Compliant TA 1 K 0 P H 2 R 5 0 K E Style Wattage Package Resistance Tolerance Type 2.5Ω = 2R50 K = 10% (standard) 50Ω = 50R0 L = 20% Standard Part Numbers Ohms 1000 Watt 10% Tolerance Ohms 2000 Watt 10% Tolerance TA1K0PHR500KE TA1K0PH1R00KE TA1K0PH2R50KE TA1K0PH5R00KE TA1K0PH7R50KE TA2K0PHR500KE TA2K0PH1R00KE TA2K0PH2R50KE TA2K0PH5R00KE TA2K0PH7R50KE TA1K0PH250RKE TA1K0PH500RKE TA1K0PH750RKE TA1K0PH1K00KE 0.5 1 2.5 5 7.5 10 15 25 50 100 144 250 500 750 1000 TA1K0PH10R0KE TA1K0PH15R0KE TA1K0PH25R0KE TA1K0PH50R0KE TA1K0PH100RKE 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • [email protected] 0.5 1 2.5 5 7.5 10 15 25 50 100 250 500 750 1000 TA2K0PH10R0KE TA2K0PH15R0KE TA2K0PH25R0KE TA2K0PH50R0KE TA2K0PH100RKE TA2K0PH250RKE TA2K0PH500RKE TA2K0PH750RKE TA2K0PH1K00KE
