Testing Instrument
Inductance: HP4284 or Equivalent.
Q: HP4285A or Equivalent.
D.C.R: Keithley 580 Micro Ohm Meter or Equivalent.
S.R.F.: HP4395A or Equivalent.
Rated Current: HP4284A, HP42841A, HPE3632A, HP34401A or Equivalent.
-Idc 1: The Current when the Inductance decreases to 90% of initial value. (Ta=25°C)
-Idc 2: The Current when the temperature of inductor increases by 40°C. (Ta=25°C)
The Rated Current indicates the smaller one between Idc 1 & Idc 2.
* Test Conditions of Inductance: 2.2µH ~ 8.2µH at 100kHz / 1V
10µH ~ 100000µH at 1kHz / 1V
* Test Conditions of Unloaded Q: 2.2µH ~ 8.2µH at 7.96MHz / 1V
