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°C ③ SRF measured using an Agilent 4395A network analyzer and an Agilent 16193A test fixture. ④ DC current at 25°C that causes the specified Inductance drop from its value without current. ⑤ Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. ⑥ Electrical specifications at 25°C | ||||||||
