RXEF050S-AP Frequently Asked Questions (FAQ)
-
Littelfuse recommends a PCB layout with a solid ground plane, minimal lead lengths, and a Kelvin connection for the sense pins to ensure accurate current measurement and minimize noise.
-
Calibration involves applying a known current to the device and adjusting the output voltage to match the expected value. Littelfuse provides a calibration procedure in the application note AN10074.
-
The RXEF050S-AP is rated for operation from -40°C to 125°C, but derating may be necessary for high-current applications or extreme environmental conditions.
-
Yes, the RXEF050S-AP is designed to withstand vibrations up to 10g peak acceleration, but additional mechanical support or potting may be necessary for extreme vibration environments.
-
Follow proper PCB layout and shielding practices, use a common-mode choke or ferrite bead on the sense lines, and ensure the device is properly grounded to minimize electromagnetic interference.
