The Würth Elektronik 74408943330 is a shielded wirewound power inductor from the WE-SPC series. It offers a nominal inductance of 33 µH with ±20% tolerance, measured at 100 kHz and 1 mA. The component is rated for a maximum current of 0.9 A with a temperature rise of 40 K, and has a typical saturation current of 1.2 A.
The inductor features a ferrite drum core and is fully shielded, which helps reduce electromagnetic interference in sensitive circuits. Its DC resistance is 0.259 Ω typical and 0.298 Ω maximum at 20°C, contributing to efficient power handling. The self-resonant frequency is 14 MHz typical, making it suitable for applications up to that frequency range.
Designed for surface-mount assembly, the component measures 4.8 mm by 4.8 mm with a height of 4.1 mm, and uses a nonstandard package. It operates over a temperature range of -40°C to +125°C, with an ambient temperature range for rated current of -40°C to +85°C. The inductor is RoHS compliant, REACH conform, halogen-free, and has an MSL of 1.
