Notes
- When ordering, please specify screening code: e.g. MS558PTA572MSZ.
- 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 the specified inductance drop 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.
Screening:
- Z = Unscreened
- Y = Unscreened (SLDC Option A)
- W = Unscreened (SLDC Option B)
- H = Coilcraft CP-SA-10001 Group A
- G= Coilcraft CP-SA-10001 Group A (SLDC Option A)
- D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
- 1/2/3 = EEE-INST-002 (Family 1) Level 1/2/3
- 4/5 = MIL-STD-981 (Family 04) Class B=4, Class S=5
- F = ESCC3201 (F4 operational life performed at 105°C)
- Screening performed to the document’s latest revision.
- Lot qualification (Group B) available.
- Testing T and U have been replaced with more detailed codes 4, 5, and 1, 2, 3, respectively. Codes T and U can still be used, if necessary. Custom testing also available.
