FEATURESʗಛ௕
• High sound quality, low distortion, and low heat generation
due to the unique design of digital audio amplifier LPF by
the use of magnetic material suitable for digital amplifier,
and superb magnetic saturation characterisitcs.
• A magnetically shielded structure prevents radiation noise
• The coil is flat wires (DA1476S type) to provide low DC
resistance.
• RoHS compliant

(1) Inductance is measured with a LCR meter 4284A* or equivalent.
(2) DC Resistance is measured with a Digital Multimeter TR6871
(ADVANTEST) or equivalent.
(3) Maximum rated 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)
