The SQH3015S-330M-LF with Power Inductors 33uH ±20% 370mA SMD,3.1x3.1x1.5mm RoHS is a surface-mount device manufactured by Coilmaster. It is a toroidal power inductor specifically designed for high-frequency, high-current applications. This inductor has a low DCR of 0.075 ohms, and a maximum rated current of 370mA, which allows it to handle currents higher than most power inductors. It is 3.1x3.1x1.5mm in size, and has a RoHS compliant lead-free construction. Furthermore, it comes with a ±20% tolerance of inductance to cover non-ideal conditions. This part is suitable for power supply, charging, and DC-DC converter applications.
