(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) Inductance Decrease Current based upon 20% inductance
reduction from the initial value
(4) Temperature Rise Current based upon 40°C temperature rise.
(Reference ambient temperature 20°C)
(5) Absolute maximum voltage 30VDCDC.
NOTICE: Please be sure that you carefully discuss your planned
purchase with our sales division if you intend to use the
product for business use etc. is severe.
