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: 1.0µH ~ 8.2µH at 100kHz / 1V

10µH ~ 47000µH at 1kHz / 1V

* Test Conditions of Unloaded Q: 1.0µH ~ 8.2µH at 7.96MHz / 1V

10µH ~ 82µH at 2.52MHz / 1V

100µH ~ 820µH at 796kHz / 1V

1000µH ~ 8200µH at 252kHz / 1V

10000µH ~ 47000µH at 79.6kHz / 1V
