Schurter recommends a PCB layout with a minimum of 1.5 mm clearance around the fuse body and a land pattern with a minimum of 0.5 mm width for the fuse legs. A detailed layout recommendation can be found in the Schurter application note.
The PFRA.090 fuse is designed to operate up to 125°C, but its melting integral (I²t) may decrease at higher temperatures. Consult the datasheet for temperature derating curves and consider using a thermally protected fuse holder to minimize thermal stress.
Schurter recommends a soldering profile with a peak temperature of 260°C, a dwell time of 3-5 seconds, and a cooling rate of 4°C/s to minimize thermal shock. Consult the datasheet for detailed soldering guidelines.
Yes, the PFRA.090 fuse is designed to withstand high vibrations and shocks. However, it's essential to ensure proper mounting and secure the fuse holder to prevent movement or dislodging during operation.
The PFRA.090 fuse is designed to handle inrush currents and high-surge applications. However, it's crucial to consider the fuse's melting integral (I²t) and the application's specific requirements to ensure proper fuse selection and protection.
