| Toroidal Chokes for Class D Amplifiers ctparts.com CTCDT Series From 4.7 H to 56 H Not shown at actual size. CHARACTERISTICS Description: Toroidal Chokes for Class D amplifiers Applications: Powered Loudspeakers, electronic motor drives, portable amps, PA systems & car amps. Testing: Inductance tested at 10kHz, 10 gauss, 0Adc Winding: Single layer wound for high self-resonant frequency Core: 10 permeability Carbonyl Micrometals(c) Core Packaging: Bulk packaged Additional Information: * L of less than 10% at 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 75C max. Miscellaneous: RoHS Compliant. Samples available. See website for ordering information.
