Specifications Quantity: 1 piece heatsink Material: Aluminum Heatsink Size: 150mm x 74mm x 10mm/5.9 inches x 2.91 inches x 0.39 inch Color: blue Specifications Made of high quality blue anodized Aluminum, provides great thermal conductivity and gives your a luxurious appearance. Multiple cooling fin design can effectively reduce the risk of hardware failure and power loss due to overheating. Maximize surface area designed in contact with the cooling air. The plenty of cooling fins increase the area of the board and thus provide for greater heat transfer. Applications: these aluminum heatsinks are widely used for computer, Power Transistor, FET, IC, Power Amplifier, Voltage Regulator, MOSFET, SCR, high-power semiconductor devices, etc.
