74404300033 Description

Short technical summary and product information.

The Würth Elektronik 74404300033 is a shielded wirewound power inductor from the WE-TPC series. It offers an inductance of 0.33µH (330nH) with ±30% tolerance, measured at 100kHz and 100mV. The component is rated for a maximum DC current of 4A with a temperature rise of 30K, and features a saturation current of 6A typical (ΔL/L<35%).

DC resistance is 8mOhm typical and 12mOhm maximum at 20°C, ensuring low conduction losses. The self-resonant frequency is 400MHz typical, supporting operation in high-frequency power circuits. The ferrite drum core and wirewound construction deliver stable inductance over a wide temperature range.

The inductor is housed in a 1919 (4848 Metric) surface-mount package measuring 4.80mm x 4.80mm x 3.00mm. It operates over -40°C to +125°C and is fully shielded to minimize EMI. The component is RoHS, REACH, and halogen-free compliant, with MSL level 1 for unlimited floor life.
