RXEF090-AP Frequently Asked Questions (FAQs)

  • Littelfuse recommends a symmetrical PCB layout with a solid ground plane and a minimum of 1 oz copper thickness to ensure optimal thermal performance and EMI reduction.
  • While RXEF090-AP is rated for operation up to 150°C, it's essential to consider the derating curves and thermal management strategies to ensure reliable operation in high-temperature environments.
  • Littelfuse recommends using their proprietary fuse holders or clips, such as the FH090 series, which are specifically designed for RXEF090-AP. These holders ensure secure retention and optimal electrical connection.
  • Littelfuse recommends a soldering profile with a peak temperature of 260°C, a dwell time of 10-30 seconds, and a ramp rate of 3°C/second to ensure reliable solder joints.
  • RXEF090-AP is designed to withstand moderate vibration levels. However, for high-vibration applications, it's recommended to use additional mechanical support or consider a fuse with enhanced vibration resistance, such as Littelfuse's RXEF090-AP-HV.
