Remark

① Inductance is measured with a LCR meter Agilent 4284A or equivalent.Test frequency at 100kHz

② DC resistance is measured with keithley 580 Milliohm Meter , or equivalent. Reference ambient temperature 25℃

③ SRF measured using an Agilent 4395A network analyzer and an Agilent 16093A test fixture.

④ DC current at 25℃ that causes the specified inductance drop from its value without current.

⑤ Current that causes the specified temperature rise from 25℃ ambient. This information is for reference only and 

does not represent absolute maximum ratings.
