It has a black anodised finish, and features an optimised profile with ridged fins for high surface area and low mass.<\/p>\n<p>Exhibiting versatility, a TO-220 package resistor may be fitted to either side of the heatsink as the thermal performance is the same for both mounting surfaces.<\/p>\n<p>Furthermore, two packages may be fitted, one each side, provided the total power dissipated does not exceed the rating of either. A TO-247 package can be fitted to the wider of the two mounting surfaces.<\/p>\n<span class=\"highlight highlight-blue\"><a href=\"https:\/\/engineernewsnetwork.com\/blog\/tt-electronics-receives-faa-part-145-aviation-repair-station-certification\/\">TT Electronics<\/a><\/span>\u2019 WMHP-HS heatsink offers a higher surface area, superior cooling performance and lower mass than key competing parts.
