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.

Samples available. See website for ordering information.
