Notes
- When ordering, please specify testing code: e.g. ML534PMM231MLZ.
- Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
- DCR is measured on a micro-ohmmeter at points indicated in the dimensional diagram.
- 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.
