DFKH-31-0007 - SCHURTER

DFKH-31-0007 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and spacing for the DFKH-31-0007?
  Schurter recommends a minimum PCB spacing of 2mm between the fuse and other components, and a minimum of 1.5mm between the fuse and the PCB edge. A larger spacing is recommended for high-voltage applications.
• Can the DFKH-31-0007 be used in high-temperature applications?
  The DFKH-31-0007 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.
• How does the DFKH-31-0007 respond to inrush currents?
  The DFKH-31-0007 is designed to handle inrush currents up to 10 times the rated current for a short duration (typically 10-20ms). However, repeated inrush events may affect the fuse's lifespan. Consult Schurter's application notes for more information.
• Is the DFKH-31-0007 suitable for use in high-vibration environments?
  The DFKH-31-0007 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.
• Can the DFKH-31-0007 be used in applications with high humidity or moisture?
  The DFKH-31-0007 is designed to operate in environments with relative humidity up to 95%. However, exposure to high humidity or moisture may affect its performance and lifespan. Consider using a fuse with a more robust design or applying conformal coating for high-humidity applications.
