RXEF090S-2 Frequently Asked Questions (FAQ)
-
Littelfuse recommends a PCB layout with a solid ground plane, minimal lead length, and a 2-3mm clearance around the device to ensure proper heat dissipation and reduce electromagnetic interference (EMI).
-
While RXEF090S-2 has a maximum operating temperature of 125°C, it's essential to consider derating the device's current rating and ensuring proper heat sinking to prevent thermal runaway. Consult Littelfuse's application notes for guidance on high-temperature applications.
-
Choose a fuse holder or clip that is specifically designed for RXEF090S-2's dimensions and meets the required electrical and mechanical specifications. Littelfuse offers a range of fuse holders and clips that are compatible with RXEF090S-2.
-
Use a wire size that matches the device's current rating (e.g., 14 AWG for RXEF090S-2's 90A rating) and is made of a material with low resistance and high temperature rating, such as copper or aluminum.
-
RXEF090S-2 is designed to withstand moderate vibration and shock, but it's crucial to ensure the device is properly secured to the PCB and the PCB is mounted securely to the chassis to prevent damage or dislodging.
