UU9.8 Line Filter Horizontal Common Mode Inductor 22mH Winding Choke For AC Adapters
Features Of The Common Mode Inductor 22mH Winding Choke For AC Adapters
* An open-body anti-noise choke coil featuring a large inductance
for a great noise control effect.
* Hybrid common mode choke and normal mode choke function.
* This series of line filter is intended for use in AC line filters
for switching power supplies.
* The differential filtering frequency response has been designed
to provide filtering at higher frequencies
while still allowing the AC line power to pass through without
loss.
* Complies with UL and electrical appliance standards.
Application Of The Common Mode Inductor 22mH Winding Choke For AC Adapters
* As a preventive measure against noise terminal voltage or power
supply in TV or VCR units
* Word Processors, ECRs, AC Adapters,
* POS terminals, Game machines, Switching power supplies
* EMI Suppression, Measuring instruments, Peripheral units

What is a Common Mode Choke?
A common mode choke is an electrical filter that blocks high
frequency noise common to two or more data or power lines while
allowing the desired DC or low-frequency signal to pass. Common
mode (CM) noise current is typically radiated from sources such as
unwanted radio signals, unshielded electronics, inverters and
motors. Left unfiltered, this noise presents interference problems
in electronics and electrical circuits.
How do I Choose a Common Mode Choke?
The main criteria for selecting a common mode choke are:
Required impedance: How much attenuation of noise is needed?
Required frequency range: Over what frequency bandwidth is the
noise?
Required current-handling: How much differential mode current must
it handle?
