MS528PMM Series
High-Reliability Power Inductors
MS528PMM Series designed for use in multi-phase VRM/VRD regulators and high current/high frequency DC/DC converters.
- Requires only 60 mm2 of board space; can handle up to 100 A.
- Tin-lead (Sn-Pb) terminations for the best possible board adhesion.

Notes
- When ordering, please specify screening code: MS528PMM151KSZ.
- Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
- DCR is measured between the two points indicated on the dimensional drawing.
- This information is for design purposes only and shall not be tested during screening.
- DC current at 25°C that causes an inductance drop of 20% (typ) from its value without current.
- Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
Due to the design of this component, DWV and IR shall not be specified or tested.
