Notes
- When ordering, please specify termination and screening codes: e.g. ST235RAR332JRZ.
- Inductance measured at 7.9 MHz using a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286 impedance analyzer.
- SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD -D test fixture.
- DCR measured on Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture.
- Current that causes a 15°C temperature rise from 125°C ambient. Because of their open construction, these parts will not saturate.
Termination:
- R = RoHS compliant matte tin over nickel over silver-platinum-glass frit.
- Q = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
- P = non-RoHS tin-lead (63/37). (Special order, added cost)
Screening:
- Z = Unscreened
- H = Coilcraft CP-SA-10001 Group A
- Screening performed to the document’s latest revision.
- Lot qualification (Group B) available.
- Custom testing also available.
- Country of origin restrictions available; prefix options G or F.
