649-51AB

Thermal heat sinks are an important technology in the world of electronic components and their use is increasing with the emergence of more powerful components. 649-51AB is one type of thermal heat sink that is designed for highly specific applications.

649-51AB is a heat sink designed for surface mount applications. The design of this heat sink is intended to provide significant thermal design flexibility in order to optimize the thermal management of power components while meeting product size, performance, and cost objectives. The sink is constructed from aluminum and has a thermal impedance rating of 0.45°C/W. This makes it an ideal choice for applications where the highest possible heat dissipation is required.

The primary function of the 649-51AB heat sink is to dissipate heat generated by components into the surrounding environment. This is achieved through a combination of conductive and convective heat transfer. The high quality aluminum material used in its construction provides excellent thermal conductivity, while the several fins incorporated into the design enhance the convection process by increasing the surface area of the heat sink, allowing for more efficient heat dissipation.

649-51AB is designed to be simple and easy to install on boards, and features a number of design considerations to ensure maximum thermal performance. It is compliant with all JEDEC and MIL-STD-752A specifications, and has a very low profile mounting option that allows for tight stack heights and reduced overall footprints. The integrated mounting clip allows for semi-threaded audible installation capability further enhancing the product’s installation efficiency.

The 649-51AB heat sink provides a wide range of potential applications, including microprocessors, ASICs, MCUs, FPGAs, and other sensitive components. It is also well suited for LED driver applications and is especially popular thanks to its low profile design. Another key application is in telecommunications applications, such as wireless base stations, where the lowest possible power consumption and highest level of heat dissipation are crucial.

649-51AB is a highly specialized thermal heat sink that provides superior heat dissipation capabilities in order to protect and ensure the optimal performance of sensitive electronic components. With its high thermal performance, low profile design, and easy installation, it is a popular choice for a variety of power electronics, LED drivers, and telecommunications applications.
