The Würth Elektronik 78438367022 is a surface-mount power inductor from the WE-MAIA series, designed for high-performance power conversion and EMI filtering applications. This shielded inductor features an inductance of 2.2 µH with a tolerance of ±20%, measured at 100 kHz and 10 mA.
Key electrical characteristics include a rated current of 9.8 A (based on a 40 K temperature rise) and a saturation current of 4.55 A typical at 10% inductance drop, extending to 10.2 A typical at 30% drop. The DC resistance is 14 mΩ typical and 16.1 mΩ maximum, ensuring low conduction losses. The self-resonant frequency is 28 MHz typical.
The inductor is housed in a compact 5.4 mm x 5.4 mm x 3.1 mm nonstandard package, suitable for space-constrained designs. It is constructed with an iron alloy core and is fully shielded to minimize electromagnetic interference. The component is qualified to AEC-Q200 Grade 1, making it suitable for automotive electronics, and operates over a temperature range of -40°C to +125°C.
