Littelfuse recommends a PCB layout with a large copper area connected to the thermal tab to dissipate heat efficiently. A minimum of 1 oz copper thickness is recommended, and the thermal tab should be soldered to the PCB to ensure good thermal conductivity.
To select the correct fuse, consider factors such as the maximum current rating, voltage rating, and interrupting rating required for your application. Also, consider the fuse's melting I²t, which should be higher than the maximum I²t of the circuit. Consult Littelfuse's selection guide or contact their technical support for assistance.
The B61089BDR is a high-speed fuse with a fast acting characteristic, making it suitable for applications requiring rapid disconnection. It has a higher interrupting rating and a smaller body size compared to other similar fuses. Consult Littelfuse's datasheets and product catalogs to determine the best fuse for your specific application.
The B61089BDR is rated for operation up to 125°C. However, its performance and lifespan may be affected at high temperatures. Consult Littelfuse's derating curves and thermal management guidelines to ensure the fuse operates within its specified limits.
To ensure proper soldering, follow Littelfuse's recommended soldering profile and guidelines. Use a solder with a melting point above 180°C, and apply a soldering iron with a temperature between 250°C to 300°C. Avoid applying excessive force or pressure, which can damage the fuse.
