MRPR-20-27-38 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.
-
Power dissipation can be calculated using the formula: Pd = (I^2 * R) + (Vcc * Icc), where I is the current through the sense resistor, R is the sense resistance, Vcc is the supply voltage, and Icc is the quiescent current.
-
The MRPR-20-27-38 is rated for operation from -40°C to 125°C, but derating is required above 85°C to ensure reliable operation.
-
Yes, the MRPR-20-27-38 is designed to withstand high-vibration environments, but it's essential to follow proper mounting and soldering techniques to ensure reliable operation.
-
Common issues can be troubleshooted by checking the PCB layout, ensuring proper soldering and mounting, verifying the sense resistor value, and monitoring the device's operating temperature and power dissipation.
