Notes
- When ordering, please specify termination and screening codes: e.g. CP312PHA473KLZ.
- Inductance measured at 100 kHz, 0.1 Vrms, using a Coilcraft SMD -A fixture in Agilent/HP 4263B LCR meter.
- DCR measured on a micro-ohmmeter and a Coilcraft CCF1010 test fixture.
- SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft CCF1232 test fixture.
- DC current at which the inductance drops 10% (typ) 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.
Termination:
- L = Silver-palladium-platinum-glass frit.
- R = Matte tin over nickel over silver-platinum glass frit. (Special order, added cost)
- T = Tin-silver-copper (95.5/4/0.5). (Special order, added cost)
- S = Tin-lead (63/37). (Special order, added cost)
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)
