DFKH-31-0003 Details

Schurter recommends a minimum PCB spacing of 2.5 mm between the fuse and other components, and a minimum of 1.5 mm between the fuse and the PCB edge. A larger spacing is recommended for high-voltage applications.
The DFKH-31-0003 is rated for operation up to 125°C, but its performance may degrade above 100°C. For high-temperature applications, consider using a fuse with a higher temperature rating or consulting with Schurter's application engineers.
The DFKH-31-0003 is designed to handle inrush currents up to 10 times the rated current for a short duration (typically 10-20 ms). However, repeated inrush events may affect the fuse's lifespan. Consult Schurter's application notes for more information.
The DFKH-31-0003 is designed to withstand moderate vibrations, but extreme vibrations may affect its performance. For high-vibration applications, consider using a fuse with a more robust design or consulting with Schurter's application engineers.
The DFKH-31-0003 is not recommended for use in parallel configurations, as this may affect its performance and reliability. Series configurations are possible, but consult Schurter's application notes for guidance on selecting the appropriate fuse rating and configuration.
