The Würth Elektronik 7440650047 is a shielded drum-core wirewound inductor from the WE-TPC series, designed for power applications requiring compact size and reliable performance. It offers an inductance of 4.7 µH with a tolerance of ±30%, measured at 100 kHz and 1 V. The component is rated for a maximum current of 4.6 A (ΔT = 30 K) and has a typical saturation current of 4.2 A (|ΔL/L| < 35%).
With a maximum DC resistance of 23 mΩ (typical 16.5 mΩ at 20 °C), this inductor provides efficient power handling with minimal losses. The self-resonant frequency is typically 40 MHz, making it suitable for switching power supplies and DC-DC converters operating in the low to medium frequency range.
The inductor is shielded to reduce electromagnetic interference, and its ferrite core material enhances magnetic performance. It is designed for surface-mount assembly with a nonstandard package measuring 10.00 mm × 10.00 mm with a height of 4.20 mm. The operating temperature range spans from -40 °C to +125 °C, ensuring reliable operation in demanding environments.
This component is RoHS3 compliant, REACH conform, and halogen-free, meeting modern environmental standards. It is suitable for general electronic equipment where high reliability and compact power inductors are required.
