(1) Inductance is measured with a LCR meter 4284A (Agilent

Technologies) or equivalent.

Test frequency at 100kHz

(2) DC resistance is measured with 34420A (Agilent Technologies) or

3541(HIOKI). (Reference ambient temperature 25°C)

(3) Maximum allowable DC current is that which causes a 10%

inductance reduction from the initial value, or coil temperature to

rise by 40°C, whichever is smaller.(Reference ambient

temperature: 20°C)

(1) LCR仪表4284A (Agilent技术)或者功½相同的仪器在100kHz下测
