Notes
- When ordering, please specify tolerance, termination and screening codes: e.g. CP312RAQR47JRZ.
- Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP E4982A impedance analyzer with Coilcraft-provided correlation pieces.
- Tolerances in bold are stocked for immediate shipment.
- Q measured using an Agilent/HP4991A with an Agilent/HP16197 test fixture.
- SRF measured using an Agilent/HP 5071C/8722ES network analyzer and a Coilcraft CCF1052 test fixture.
- DCR measured on a micro-ohmmeter and a Coilcraft CCF1010/A test fixture.
- Maximum current that can be applied at 125°C.
Tolerance:
- G = 2%
- H = 3%
