RXEF135-AP Frequently Asked Questions (FAQs)

  • A good PCB layout for the RXEF135-AP should ensure that the fuse is placed in a location that allows for good heat dissipation, and that the traces are wide enough to handle the maximum current rating. It's also recommended to use a solid ground plane and to keep the fuse away from high-voltage components.
  • The RXEF135-AP is designed to operate in temperatures up to 125°C, but its performance may degrade at higher temperatures. It's recommended to derate the fuse's current rating by 1.5% for every 10°C above 85°C to ensure reliable operation.
  • The RXEF135-AP is designed for low-frequency applications, and its performance may degrade at high frequencies. It's recommended to use a fuse with a higher frequency rating, such as the RXEF135-HF, for applications above 100 kHz.
  • The recommended soldering profile for the RXEF135-AP is a peak temperature of 260°C for 10-15 seconds, with a ramp-up rate of 3-4°C/second and a ramp-down rate of 6-8°C/second. It's also recommended to use a solder with a melting point above 217°C.
  • Yes, the RXEF135-AP is compatible with lead-free soldering processes, but it's recommended to use a solder with a melting point above 217°C to ensure reliable operation.
