The Würth Elektronik 74477820 is a shielded wirewound power inductor from the WE-PD series, designed for surface mount applications. It offers an inductance of 100 µH with ±20% tolerance, measured at 1 kHz and 250 mV. The inductor is rated for a continuous current of 620 mA (ΔT=40K) and can handle a performance rated current of 0.91 A per IEC 62024-2 Class C. Saturation current is 0.76 A typical at 10% inductance drop and 0.95 A typical at 30% drop.
DC resistance is 580 mΩ typical and 790 mΩ maximum at 20°C. The self-resonant frequency is 9 MHz typical, and the maximum operating voltage is 120 V. The component is built with a ferrite core and is fully shielded, making it suitable for noise-sensitive applications.
The inductor is housed in a nonstandard 7332 package measuring 7.3 mm x 7.3 mm x 3.2 mm, suitable for surface mount assembly. It operates over a temperature range of -40°C to +125°C and is AEC-Q200 Grade 1 qualified, ensuring reliability in automotive and industrial environments. The component is RoHS, REACH, and Halogen Free compliant.
