Notes
- When ordering, please specify screening code: e.g. MS598PTA223KSZ.
- Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A or equivalent.
- DCR measured on a micro-ohmmeter.
- SRF measured using an Agilent/HP 8753D network analyzer.
- DC current at 25°C that causes a 10% (typ) inductance drop from its value without current.
- Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
