  1. When ordering, please specify screening code: e.g. ST358PWA103MLZ.
  2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
  3. DCR measured on a micro-ohmmeter.
  4. SRF measured using Agilent/HP 4395A network analyzer or equivalent.
  5. DC current at which the inductance drops from its value without current.
  6. Current that causes the specified temperature rise from 25°C ambient.
