RUEF900-2 - LITTELFUSE

RUEF900-2 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance of the RUEF900-2?
  A recommended PCB layout for optimal thermal performance would be to have a large copper area connected to the thermal pad, with multiple vias to dissipate heat. Additionally, keeping the component away from other heat sources and ensuring good airflow can help.
• How do I ensure the RUEF900-2 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 thermal pad. Use a soldering technique that minimizes the time the iron is in contact with the component.
• What is the maximum allowed voltage transient for the RUEF900-2?
  The maximum allowed voltage transient for the RUEF900-2 is 1.5 times the maximum rated voltage, but not exceeding 1.5 kV. It's essential to ensure that the device is not exposed to voltage transients exceeding this limit to prevent damage.
• Can I use the RUEF900-2 in a high-reliability application?
  Yes, the RUEF900-2 is suitable for high-reliability applications. It's designed to meet the requirements of IEC 61071 and has a high surge withstand capability, making it a reliable choice for demanding applications.
• How do I select the correct fuse holder or clip for the RUEF900-2?
  When selecting a fuse holder or clip for the RUEF900-2, ensure it is compatible with the device's dimensions and has a secure grip to prevent the fuse from being dislodged. Consult the datasheet and manufacturer's recommendations for compatible fuse holders or clips.
