VRM/ VRD Power Inductors – MVR

The MVR series provides greater current handling capability than any other power inductor its size. While requiring only one square centimeter of board space, this inductor can handle up to 36 Amps of current.

These shielded inductors were developed for multi-phase voltage regulators and are ideal for use in DC-DC converters, battery-powered devices and high current power supplies. Their flat wire construction ensures very low DC resistance and offers an excellent performance-toheight ratio. The materials used in these parts eliminate all thermal aging issues.

The MVR12xxT is a high efficiency part that features very low core loss. The MVR12xxC provides soft saturation and is unaffected by part temperature up to 125°C. Refer to the comparison curves for L vs Current and ESR vs Frequency for performance differences.
