WV Series Heatsinks For TO-220 and TO-247 devices T220 0.72" (18.3mm) T247 0.92" (23.4mm) 0.63" (16.0mm) T220 1.20" (30.5mm) T247 1.20-1.26" (30.5-32.0mm) 0.14" (3.6mm) T220 0.50" (12.7mm) T247 0.71" (18.0mm) Ohmite Manufacturing has launched a series of heatsink solutions for use with our popular TO-220 and TO-247 power resistors, or similarly packaged semiconductors. These self aligning heatsinks feature solderable feet for through-hole placement, and an integrated clip which provides 13.2 (lbf) of force on the center of the resistor, enhancing thermal performance and reducing parts count and assembly time. SPEciFicATiONS Heat Sink: Aluminum alloy 6063T5 or equivalent. Copper alloy C110 or equivalent Spring Clip: Music wire, per ASTM A228 Foot: Cold-rolled steel, per ASTM A366, commercial quality or equivalent Insulator: (optional) Sil-pad 900-S, K6 800-S, and K10, or equivalent Mounting: thru-hole, vertical Suggested Sil Pad: Sil-Pad 900S (Manufactured by Bergquist) Clip Force: 13.2 lbf.
