Product details

1 µH, 17 A, AEC-Q200 — what the ratings mean for the BOM

The Murata DFEH10040D-1R0M=P3 is a shielded power inductor from the DFEH10040D series, rated 1 µH ±20% with a continuous current of 17 A and a saturation current of 24 A. AEC-Q200 qualification means this inductor passed the full automotive passive-component stress suite: thermal shock, vibration, moisture resistance, and solder heat. The -40°C to 155°C operating range covers under-hood and transmission-bay ambient profiles with margin for self-heating.

Obsolete — sourcing path for existing BOM lines

Murata has marked the DFEH10040D-1R0M=P3 as obsolete.

Frequently asked questions

What is the saturation current of DFEH10040D-1R0M=P3?

The saturation current (Isat) is 24 A, which is the DC current at which the inductance drops by a specified percentage — typically 30% for this class. The rated continuous current is 17 A, so the part has 7 A of headroom before saturation effects become significant.
