The 744043004 is a shielded wirewound power inductor from Würth Elektronik's WE-TPC series, designed for surface-mount applications. It offers an inductance of 4.7 µH with a tolerance of ±30%, measured at 100 kHz and 100 mV. The component is rated for a maximum current of 1.55 A (based on a 30 K temperature rise) and has a typical saturation current of 1.7 A (at |ΔL/L| < 35%).
The inductor features a DC resistance of 50 mΩ typical and 70 mΩ maximum at 20 °C, along with a self-resonant frequency of 60 MHz typical. It operates over a temperature range of -40 °C to +125 °C, with an ambient temperature range of -40 °C to +95 °C when referring to the rated current. The component is shielded and uses a ferrite core, providing effective electromagnetic interference suppression.
Packaged in a 1919 (4848 Metric) surface-mount case with dimensions of 4.80 mm × 4.80 mm and a height of 2.80 mm, this inductor is suitable for space-constrained power supply designs. It is RoHS3 compliant, REACH conform, halogen-free, and has a moisture sensitivity level of 1 (unlimited shelf life). The component is designed for general electronic equipment and is not authorized for use in applications requiring higher safety standards without specific agreement.
