CTCDTF-09401 Datasheet, PDF (1/2 Pages) Central Semiconductor Corp – Toroidal Chokes for Class D Amplifiers

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.
