Notes
- When ordering, please specify termination and screening codes: e.g. ST450PHD473MAZ.
- Per winding. Tested at 100 kHz, 0.1 Vrms, 0 Adc.
- Q measured at 1 MHz.
- DC current at 25°C that causes the inductance to drop 10% (typ) from its value without current.
Termination:
- A = Gold over nickel over moly-mag terminations
- C = Tin-lead (63/37) over gold over nickel over moly-mag. (Special order, added cost)
- F = Tin-silver-copper (95.5/4/0.5) over silver-platinum glass frit. (Special order, added cost)
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)
- Screening performed to the document’s latest revision.
- Custom screening also available
