Notes
- When ordering, please specify screening code: e.g. ST558PTA572MLZ.
- 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.
- Typical DC current at which the inductance drops the specified amount from its value without current.
- Typical current that causes the specified temperature rise from 25°C ambient.
Screening:
- Z = Unscreened
- Y = Unscreened (SLDC Option A)
- W = Unscreened (SLDC Option B)
- H = Group A screening per Coilcraft CP-SA-10001
- G = Coilcraft CP-SA-10001 Group A (SLDC Option A)
- D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
Custom screening also available.
