ECS-MPI4040 Miniature Automotive Power Inductors ECS ECS-MPI4040 Miniature Automotive Power Inductors are high-current, high-frequency inductors that handle high transient inrush current spikes and have a rugged construction. These inductors are AEC-Q200 qualified and operate at a temperature range of -55°C to +125°C. The magnetically shielded components support a frequency range of 20kHz to 10MHz, an inductance range from 0.09µH to 22µH, and a current range from 1.1A to 32.0A. The ECS-MPI4040 inductors are halogen-free, lead-free, RoHS compliant, and feature PPAP support.
