Notes
- Please specify tolerance, termination and screening codes: e.g. ST450PHF105KLZ.
- Inductance measured at 100 kHz, 0.1 Vrms, using Coilcraft SMD-A fixture in Agilent/HP 4263B impedance analyzer or equivalent.
- DCR measured on micro-ohmmeter and a Coilcraft CCF859 test fixture.
- SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft CCF1301 test fixture.
- DC current at which the inductance drops 10% (typ) from its value without current.
Tolerance:
- J = 5%
- K = 10%
Termination:
- L = Silver-palladium-platinum-glass frit terminations.
- 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 CPSA-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.
