The Würth Elektronik 78438357022 is a shielded wirewound power inductor from the WE-MAIA series. It features a drum core construction with an iron alloy core, providing an inductance of 2.2 µH with ±20% tolerance. The component is rated for a continuous current of 7.1 A (ΔT = 40 K) and has a typical DC resistance of 22 mΩ, with a maximum of 26 mΩ. The saturation current is 4.6 A typical at 10% inductance drop and 9.2 A typical at 30% drop. The self-resonant frequency is 35 MHz typical.
This inductor is designed for surface mount assembly in a nonstandard 4030 package (4.1 mm x 4.1 mm x 3.1 mm max). It is qualified to AEC-Q200 Grade 1, making it suitable for automotive electronics. The operating temperature range is -40°C to +125°C, with ambient temperature up to +85°C for rated current. The component is RoHS compliant, REACH conform, and halogen free.
Typical applications include DC-DC converters, power supply filtering, and EMI suppression in automotive and industrial systems. The shielded construction minimizes electromagnetic interference. The wirewound technology ensures high current handling and low core losses.
