Thermal ratings are for optimum mounting in free air. HS04 0.95C/W HS01 11.6C/W HS05 0.85C/W HS02 4.5C/W APEX MICROTECHNOLOGY CORPORATION * TELEPHONE (520) 690-8600 * FAX (520) 888-3329 * ORDERS (520) 690-8601 * EMAIL prodlit@apexmicrotech.com 1 HS09 11.7C/W HS14 2C/W CAGE JACKS HS11 0.68C/W With liquid cooling the HS11 thermal rating can be reduced to .1C/W. MS02 Part number MS02 consists of a package of 8 cage jacks. These are mounted directly in a print circuit board. Use a spacer between the PCB and the heatsink to avoid short circuits. HS13 1.48C/W APEX MICROTECHNOLOGY CORPORATION * 5980 NORTH SHANNON ROAD * TUCSON, ARIZONA 85741 * USA * APPLICATIONS HOTLINE: 1 (800) 546-2739 2 SOCKET NOTES: 1. Base material is aluminum, 0.002" thick. Do not allow the washer to touch pins of the amplifier. 2. For optimum thermal transfer, avoid abrasive handling of washers which can damage their 0.5mil thick layer of thermal compound with which each side is coated. 3. The dry thermal compound will flow filling header to heatsink voids as soon as the material reached 60C. 4. Do not store unused thermal washers above 40C. 5. A new washer must be used for each mounting. 6. Part number TW03 consists of a package of 10 washers. 7. Thermal resistance is 0.1C/W.
