Littelfuse recommends a PCB layout with a large copper area for heat dissipation, multiple vias for thermal conduction, and a minimum of 2 oz copper thickness. A thermal pad or heat sink can also be used to improve thermal performance.
Littelfuse recommends using a soldering iron with a temperature range of 250°C to 260°C, and a solder with a melting point of 217°C to 220°C. The component should be soldered within 3 seconds to 5 seconds, and the solder joints should be inspected for quality and cleanliness.
The L70QS350.X has a maximum surge current rating of 350 A, which is specified in the datasheet. However, it's essential to note that the surge current rating may vary depending on the specific application and environmental conditions.
The L70QS350.X has a maximum operating temperature of 150°C, making it suitable for high-temperature applications. However, it's crucial to ensure that the component is properly derated for temperature to avoid thermal runaway and ensure reliable operation.
Littelfuse recommends selecting a fuse holder or clip that is specifically designed for the L70QS350.X, taking into account the fuse's physical dimensions, current rating, and voltage rating. The fuse holder or clip should also be compatible with the PCB layout and assembly process.
