(1) Inductance is measured at f=1kHz, Vosc=1V on LCR meter HP4284A or equivalent.
(2) The rated DC current is that which the inductance value decreases 10% by the excitation of DC current.
(3) Self-resonant frequency is measured with Network Analyzer 3577A(HP), MS560J(Anritsu) or equivalent.
(4) DC resistance is measured with Digital Multimeter TR6871(Advantest) or equivalent.
