Littelfuse recommends a thermal pad on the bottom of the device, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended.
Littelfuse recommends using a soldering iron with a temperature of 250°C to 260°C, and a solder with a melting point of 180°C to 190°C. Apply a small amount of solder to the thermal pad and reflow it according to the recommended soldering profile.
The SH350 can withstand surge currents up to 100 A for 10 ms, but this may vary depending on the specific application and environmental conditions. It's essential to consult with Littelfuse or a qualified engineer to determine the suitable surge current rating for your specific use case.
The SH350 is rated for operation up to 150°C, but its performance may degrade at higher temperatures. Littelfuse recommends derating the device's current rating by 1.5% per degree Celsius above 125°C to ensure reliable operation.
Littelfuse offers a range of fuse holders and clips specifically designed for the SH350. Select a holder or clip that matches the device's physical dimensions and meets the requirements of your application. Consult the Littelfuse website or contact their technical support for guidance on selecting the correct fuse holder or clip.
