PA systems & car amps.

Testing: Inductance is tested at 10kHz, 10 gauss, 0Adc.

Winding: Single layer wound for high self-resonant frequency.

Core: 10 permeability Carbonyl Micrometals© Core.

Packaging: Bulk Packaged.

Additional Information:

D

• L of less than 10% a currents greater than 100A

Class-D Operation 250kHz - 500kHz

•

High Linearity Under Peak Bias Conditions

•

Extremely Low Loss Under Typical Class-D ripple Current conditions

•

Reduced THD Due to Highest Linearity

•

Custom values & horizontal mounted configurations available upon request.

•

Note: Application should limit long term absolute temperature of component to

be 75°C Max.

Samples available. See website for ordering information.
