Toroidal Chokes for Class D Amplifiers www.ctparts.com CTCDTF Series From 4.7 µH to 56 µH CHARACTERISTICS Description: Toroidal Chokes for Class D amplifiers. Applications: Powered Loudspeakers, electronic motor drives, portable amps, 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: • DL 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. Miscellaneous: RoHS Compliant. Samples available. See website for ordering information.
