Theย WTW002ย is a thermal washer designed to go between theย WHS302ย heatsink and one of theย WTCP5V5A,ย WTC3243,ย WTC3243HB, orย WHY5640ย temperature controllers, or theย WLD3343,ย WLD3343-2L,ย WLD3343-3A,ย WLD3343-3Lย orย WLD3343HBย laser diode drivers. The WTW002 thermal washer is made of a non-silicone, flexible graphite material, and does not break down or out-gas under high heat conditions. One side has adhesive. We recommend that you install the adhesive side to the heatsink.
The controllers operate to 500 mA without any additional heatsinking (assuming 5 V operation). To operate up to 1 A, add theย WTW002ย thermal washer and theย WHS302ย heatsink. To operate to the full 2.2 A, add a fanย WXC303ย (5 V) orย WXC304ย (12 V). For convenience, a kit with two 0.75″ and two 1″ screws is available:ย WXC305.
Kits combine these elements:ย WEV300ย (includes thermal washer, heatsink and screw kit),ย WEV301ย (includes thermal washer, heatsink, screw kit, and a +5 V fan) orย WEV302ย (includes thermal washer, heatsink, screw kit, and a +12 V fan).
The prior revision of the thermal washer was an alumina-silicone-fiberglass composite and pale gray. Clickย hereย for the datasheet for that revision.
