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© 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.
