Notes
- When ordering, please specify screening code: ST464PMR101LEZ
- Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
- DCR is measured on a micro-ohmmeter at points indicated in the diagram below.
- DC current 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. Temperature rise is highly dependent on many factors including pcb land pattern, trace size, air flow, and proximity to other components. Therefore temperature rise should be verified in application conditions.
Screening:
