Notes
- When ordering, specify termination and screening codes: e.g. ST124RAA24NJRZ.
- Inductance measured at 250 MHz using an Agilent 4286A (or equivalent) with a Coilcraft CCF1426 test fixture using the listed correlation.
- Q is measured at 250 MHz on an Agilent 4991 (or equivalent) with a Coilcraft CCF1481 test fixture.
- SRF is measured on an Agilent 8753ES (or equivalent) with a Coilcraft CCF1406 test fixture.
- DCR is measured on a Keithley 580 Micro-ohmmeter (or equivalent) with a Coilcraft CCF1099 test fixture.
- Maximum current that can be applied at 125°C.
Termination:
- R = Matte tin over copper over nickel over molybdenum-manganese
- P = Tin-lead (63/37) over tin over copper over nickel over molybdenum-manganese
- Q = Tin-silver-copper (95.5/4/0.5) over tin over copper over nickel over molybdenum-manganese
Screening:
- Z = Unscreened
- H = Coilcraft CP-SA-10001 Group A
- Screening performed to the document’s latest revision.
- Custom testing also available.
