CTCDT Series

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

Testing: Tested on an HP4284A at 10 kHz 0.25Vrms.

Core: 10 permeability Carbonyl Micrometals© Core

Packaging: Bulk packaged

Additional Information:

ΔL 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 75°C max.

Miscellaneous: RoHS Compliant.

Samples available. See website for ordering information.
