Note
(1) Inductance is measured by LCR-meter 4284A/4286A (HP) or equivalent.
(2) Inductance test condition: SLF0301/0302L/0502:100KHz/1.0V,
SLF0302/0403/0503/0504/0703/0705/1004/1005: 1.0 H~8.2H:7.96MHz/0.5V,
10.0 H~82.0 H:2.52MTTHz/0.5V,More than 100.0 H at 1.0KHz/1.0V.
(3) DC Resistance is measured by HP4338B Milliohms Meter or equivalent.
(4) Rated current is measured by LCR-meter 3260B (WK) & DC Bias 3265B(WK) at 1.0KHz/1.0V.
(5) 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).
(6) Operating temperature -55
~ +125 .
(7) All test data is referenced to 25
ambient.
