744775247

The 744775247 is a fixed inductor manufactured by Würth Elektronik, part of the WE-PD2 series of SMT power inductors. This unshielded drum core inductor features a ferrite core and wirewound construction, providing an inductance of 470 µH with ±10% tolerance. It is rated for a maximum DC current of 0.36 A (ΔT = 40 K) and has a typical saturation current of 0.38 A. The DC resistance is typically 1.37 Ω and maximum 1.96 Ω. The self-resonant frequency is 3.4 MHz, and the maximum operating voltage is 120 V DC. The component is designed for surface mount assembly in a nonstandard package, with dimensions 7.80 mm length, 7.00 mm width, and 5.50 mm height. It operates over a temperature range of -40°C to +125°C, with an ambient temperature range of -40°C to +85°C when referring to rated current. The inductor is compliant with RoHS, REACH, and halogen-free standards, with MSL 1. It is suitable for use in power supply circuits, DC-DC converters, and other general electronic equipment where moderate inductance and current handling are required.
