Q4008LH4 Frequently Asked Questions (FAQs)

  • The recommended PCB footprint for the Q4008LH4 is a rectangular pad with a size of 2.5mm x 1.5mm, with a 0.5mm radius corner and a 0.3mm spacing between pads.
  • To ensure reliable soldering, use a soldering iron with a temperature of 250°C to 260°C, and apply a small amount of solder paste to the pads. Use a soldering technique that minimizes the risk of overheating the component.
  • The maximum surge current rating for the Q4008LH4 is 100A for 8.3ms, as per the IEC 61000-4-5 standard.
  • Yes, the Q4008LH4 is rated for operation up to 150°C, making it suitable for high-temperature applications. However, the component's performance and reliability may degrade at elevated temperatures.
  • To select the correct fuse rating, consider the maximum current and voltage ratings of your application, as well as the desired response time and fault-clearing characteristics. Consult the datasheet and application notes for guidance.
