Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

744773047 is a surface-mount (SMD) power inductor from the WE-PD2 series launched by Würth Elektronik, featuring a 4532 package (4.5mm × 4mm × 3.2mm), with an inductance value of 4.7μH, a rated current of 1.82A, and a maximum DC resistance of 110mΩ. It is suitable for applications such as switching power supplies (DC-DC), power management, and industrial control.

This inductor uses a ferrite core and wound structure, offering high current carrying capacity and low loss, making it suitable for high-efficiency switching power supplies in applications such as computers, portable devices, mobile phones, and DC-DC converters.

744773047 Features

High current carrying capacity

Rated current 1.82A, saturation current (Isat) 2.46A, suitable for high-current applications.

Low DC resistance (DCR) 110mΩ, reducing power loss.

Wide temperature operating range: -40°C to +125°C, suitable for industrial and automotive electronic environments.

Unshielded design: open structure, suitable for high-density PCB layouts, reducing electromagnetic interference (EMI) effects.

High self-resonant frequency (SRF): 45MHz, suitable for high-frequency switching power supplies, reducing the impact of parasitic capacitance.
