SH400 Frequently Asked Questions (FAQ)

  • A good PCB layout for the SH400 should ensure that the high-current paths are short and wide, and that the device is placed close to the power source. Additionally, a solid ground plane and adequate thermal management are crucial for reliable operation.

  • To select the correct fuse rating, consider the maximum current and voltage ratings of your circuit, as well as the fault current and energy let-through requirements. Consult the Littelfuse fuse selection guide or contact their technical support for assistance.

  • The SH400 is rated for operation from -40°C to 125°C, but derating may be necessary for high-current applications. Consult the datasheet or contact Littelfuse for specific guidance on temperature derating.

  • Yes, the SH400 is designed to withstand high-vibration environments. However, it's essential to ensure proper PCB mounting and secure the device to prevent movement or damage. Consult the Littelfuse application note on vibration testing for more information.

  • Follow the recommended soldering profile and procedures outlined in the Littelfuse soldering application note. Ensure the PCB is clean and free of oxidation, and use a solder with a melting point compatible with the SH400's lead finish.
