In addition to miniaturization, excellent heat resistance and high current handling are achieved due to high magnetic saturation characteristics.
Our company has expanded the lineup of metal composite power inductors, METCOM, for automotive applications. In addition to the MPXV series, which offers a wide range of size variations, and the MPEV series, which enables operation at high temperatures of up to 180°C, we have released the MPGV series, which achieves a vibration resistance of 50G due to its high vibration-resistant structure. The MPXV, MPEV, and MPGV series are power inductors that, by adopting a metal composite structure, enable miniaturization and excellent heat resistance and high current handling due to their high magnetic saturation characteristics. The MPXV series supports up to 155°C and offers a rich variety, while the MPEV series achieves even greater heat resistance with a rating of 180°C. The MPGV series realizes a vibration resistance of 50G due to its high vibration-resistant structure. Each series complies with the automotive standard AEC-Q200.

Applications/Examples of results
The MPXV, MPEV, and MPGV series are very useful as inductors for boosting and bucking in automotive switching DC/DC converters, as well as for input/output filters. In recent years, automobiles have made significant strides in electronics, with features like fully LCD meter cluster panels, and there is a growing demand for high-speed data processing, leading to the installation of numerous high-performance ECUs (Electronic Control Units) equivalent to computer levels. Due to the demand for miniaturization in their power supplies, high-speed switching of DC/DC converters has become one of the trends. Naturally, addressing the harsh temperature conditions and transient phenomena unique to automotive applications enhances the advantages of metal composite inductors significantly. They are suitable for various automotive ECU applications that require high heat resistance and vibration resistance, including LED headlights, meter cluster panels, head-up displays (HUD), electric water pumps (EWP), electric oil pumps (EOP), and electric power steering (EPS).
