Common Mode Chokes - Ultra High Current Power Filtering

(21)

Stock Locator Button

Laird Technologies' ultra high current CM chokes provide small form factor, high performance, and economical power filtering for common mode noise in applications up to 75 amps. Multi-line, surface mount filters provide EMI suppression for groups of conductors like power traces and high-speed data lines. Effective filtering into the GHz range

Common Mode Chokes - Low Frequency Power Filtering


Stock Locator Button

This common mode chokes construction provides for a more lean and cost saving approach then comparable larger, heavier, wire-wound toroidal inductors. This part provides excellent low frequency attenuation of common mode noise, within the frequencies of 100 kHz and 25 MHz. This part is great for power supply filtering, and other low frequency applications.

Stock Locator Button

These chokes exhibit superior impedance performance well into the 100 kHz range and below. The internal construction of these chokes are of the wound toroidal fashion. They use a large number of cable pairs twisted or non-twisted. This configuration reduces RFI and cross talk associated with balanced wires found in most common chokes. With typical peak impedances ranging from 2 kohms to 13 kohms in the frequency ranges of 18 to 80 MHz these ...
