Notes
- When ordering, specify tolerance and testing codes: e.g. MS394RAT10GSZ.
- Inductance measured at 800 MHz on an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A test fixture and correlation.
- Q measured at 800 MHz on an Agilent/HP 4291A or equivalent with a 16193A test fixture or equivalent.
- SRF measured on an Agilent/HP 8753ES or equivalent with a Coilcraft CCF1268 test fixture. Parts with SRF >5 GHz are verified to >5 GHz in screening.
- DCR measured on a Keithley 580 Micro-Ohmmeter or equivalent.
Tolerance:
- G = 2%
- J = 5%
- K = 10%
