3403.0287.11 - SCHURTER

3403.0287.11 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and spacing for this fuse?
  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 fuse holder or clip is also recommended to ensure secure mounting.
• Can I use this fuse in a high-vibration environment?
  Yes, the 3403.0287.11 fuse is designed to withstand high-vibration environments. It meets the IEC 60068-2-6 vibration test standard, which simulates vibrations up to 10g acceleration.
• Is this fuse suitable for use in high-temperature applications?
  The 3403.0287.11 fuse has a rated operating temperature range of -40°C to +125°C. However, it's recommended to derate the fuse's current rating by 1.5% per °C above 85°C to ensure reliable operation.
• Can I use this fuse in a humid or wet environment?
  The 3403.0287.11 fuse meets the IEC 60068-2-30 humidity test standard, which simulates humid environments up to 95% relative humidity. However, it's recommended to apply a conformal coating or potting compound to protect the fuse from moisture in extremely wet environments.
• What is the recommended soldering profile for this fuse?
  Schurter recommends a soldering profile with a peak temperature of 260°C, a dwell time of 3-5 seconds, and a cooling rate of 4°C/second. It's also recommended to use a solder with a melting point above 217°C.
