APPLICATION NOTES
PROPER HEAT SINKING TECHNIQUES ARE ESSENTIAL TO PERFORMANCE OF A TAP
RESISTOR. 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 CON-
DUCTION TO THE HEATSINK R TH -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 REC-
OMMENDED 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 ALUMI-
NUM HEAT SINK (HTTP://WWW.OHMITE.COM/TA1K0-SINK.HTML) IS AN EXAMPLE
OF PROPERLY DESIGNED HEAT SINK.
