Notes
- When ordering, please specify screening code: e.g. ML427PJB335MLZ.
- Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A.
- DCR measured on a micro-ohmmeter.
- SRF measured using an Agilent/HP 8753ES or equivalent.
- Typical DC current that causes the specified inductance drop 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 Coil- craft CP-SA-10001
- G = Coilcraft CP-SA-10001 Group A (SLDC Option A)
- D = Coilcraft CP-SA-10001 Group A (SLDC Option B)
- Screening performed to the document’s latest revision.
- Custom testing also available.
- Country of origin restrictions available; prefix options G or F.
