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 = (I² x R) + (Vcc x Icc), where I is the current through the sense resistor, R is the sense resistor value, Vcc is the supply voltage, and Icc is the quiescent current.
The MDSM-4R-22-33 has an operating temperature range of -40°C to +125°C, with a maximum junction temperature of 150°C.
Yes, the MDSM-4R-22-33 is designed to withstand high-vibration environments, with a vibration rating of 10-2000 Hz, 10 G peak acceleration.
To ensure EMC, Littelfuse recommends following proper PCB design and layout guidelines, using shielding and filtering components, and meeting relevant regulatory standards such as IEC 61000-4-2 and IEC 61000-4-4.
