Bourns provides a recommended PCB layout and land pattern in their application note AN164, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance and minimize parasitic effects.
To handle high inrush current, it's recommended to add a soft-start circuit or an NTC thermistor in series with the fuse to limit the inrush current. Additionally, ensure that the power supply can handle the inrush current and that the fuse is properly sized for the application.
The maximum allowable voltage drop across the fuse is not explicitly stated in the datasheet. However, as a general rule, it's recommended to keep the voltage drop below 1V to ensure reliable operation and minimize power loss. Consult with Bourns' technical support for specific guidance on your application.
While the fuse is rated for operation up to 125°C, it's essential to consider the derating curves and temperature coefficients provided in the datasheet. Ensure that the fuse is properly derated for your specific operating temperature range to maintain reliability and performance.
To select the correct fuse, consider factors such as the maximum current, voltage, and power rating required for your application. Consult Bourns' selection guides and application notes, and consult with their technical support if needed.
