DLH-14-0002 - SCHURTER

DLH-14-0002 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for the DLH-14-0002?
  Schurter provides a recommended PCB layout and land pattern in their application notes or design guides. It's essential to follow these guidelines to ensure proper soldering and to prevent thermal issues.
• How do I ensure the fuse is properly soldered to the PCB?
  To ensure proper soldering, use a soldering iron with a temperature of 250°C to 270°C, and apply a small amount of solder paste to the PCB pads. Hold the fuse in place with tweezers and apply gentle pressure while soldering. Avoid applying excessive force, which can damage the fuse or PCB.
• What is the maximum allowable voltage drop across the fuse?
  The maximum allowable voltage drop across the DLH-14-0002 fuse is typically specified as 1.5V to 2.5V, depending on the application and operating conditions. Exceeding this voltage drop can lead to premature fuse failure or reduced reliability.
• Can I use the DLH-14-0002 in high-temperature applications?
  The DLH-14-0002 is rated for operation up to 125°C. However, it's essential to derate the fuse's current rating according to the temperature derating curve provided in the datasheet to ensure reliable operation in high-temperature applications.
• How do I select the correct fuse rating for my application?
  To select the correct fuse rating, consider the maximum expected current, voltage, and power dissipation in your application. Consult the datasheet and application notes for guidance on selecting the appropriate fuse rating. It's also recommended to consult with a Schurter application engineer or a qualified electrical engineer for complex applications.
