The Würth Elektronik 74477730 is a WE-PD series SMT shielded power inductor with a drum core wirewound construction. It offers an inductance of 1000 µH (1 mH) with ±20% tolerance. The rated current is 0.2 A based on a 40 K temperature rise, with a maximum DC resistance of 6 Ω. Two saturation current ratings are provided: 0.25 A typical at 10% inductance drop and 0.31 A typical at 30% drop. The self-resonant frequency is 2.2 MHz typical.
This inductor is shielded for reduced EMI and comes in a nonstandard 7345 package (7.3 mm x 7.3 mm x 4.5 mm). It is qualified to AEC-Q200 Grade 1 and operates over -40°C to +125°C. The component is RoHS compliant, REACH conform, and halogen-free. Performance rated current per IEC 62024-2-2020 is 0.37 A max.
Ideal for power supply filtering, DC/DC converter input/output, and automotive electronics where low current and high inductance are needed. The ferrite core material ensures stable performance across temperature.
