Figure 2 shows a typical connection diagram for the attenuation of both
differential and common-mode noise when used as an input filter to a DC/DC
converter, while Figure 3 shows the recommended layout. Noise introduced
into circuits is dependent upon the characteristics of the load, layout and
grounding techniques, and cabling. Since application requirements differ, the
final circuit configurations may be best obtained through empirical testing.

Conducted emissions Performance
Conducted Emissions standards imposed by governing agencies must be
met at the system level, not the component level. Many designers, however,
apply these standards to the individual components to assure system-level
compliance. The following performance graphs show the Conducted Emis-
sions improvements seen when using an FLT-100V series filter in series with
the input lines of a typical switching DC/DC converter. Conducted Emis-
sions testing was performed within a EMCO 5305 GTEM test cell utilizing
EMCO automated EMC test software. Signal levels were measured from an
EMCO 3825/2 Line Impedance Stabilization Network (LISN) using a Hewlett
Packard 8568B spectrum analyzer with an attached Hewlett Packard 85650A
quasi-peak adapter in peak detection. Limits are based on FCC Part 15
Subpart J Class A and B, as well as EN 55022 Class A and B.
