Rated for 450 mA continuous current with a saturation current floor of 510 mA, the 650 mOhm max DCR sets the I²R conduction loss that drives the temperature rise under load. Qualified to AEC-Q200, the part operates across -40°C to +125°C, covering the automotive under-hood temperature band and industrial enclosures without derating concerns. ## Shielded construction and board-fit footprint The ferrite core and full magnetic shield contain the flux within the 3.90 mm × 3.90 mm body — adjacent high-density routing and nearby sensitive traces see minimal coupled noise, a common concern in power-stage layouts.","metaTitle":"Coilcraft LPS4018-473MRC Shielded Power Inductor, 47 µH","metaDescription":"Coilcraft LPS4018-473MRC drum core shielded inductor, 47 µH ±20%, 450 mA rated current, 650 mOhm DCR.
