TDK Corporation presents the new
ACP3225 series of common-mode
filter that offers improved
performance in a smaller package when
compared to existing products. Thus, the
new wire wound common-mode filter
features a current capability of 1.2 A and
a common-mode impedance of 1,000 ?.
These values are 20 percent and 25 per
cent higher, respectively than those of
the existing ACM4532 series.
With a form factor of IEC 3225 (3.2 x
2.5 x 2.3 cumm) the ACP3225 series
offers a significantly smaller component
for use in the power supply circuitry of
increasingly compact electronic
devices. Mass production was launched
in April 2012.
Electronic devices are getting smaller
and smaller while offering an increasing
range of functions. Moreover, they tend
to be used continuously for longer
periods and often under high-load
conditions with more noise. As a result,
the EMC requirements for these
applications are extremely high.
The main advantages of the new
ACP3225 series were made possible by
TDK's advanced materials and process
technologies. Their cores make use of an
especially low-loss ferrite material, and
the automated high-precision winding
process for the coil section enables the
component's compact design.
