7 A V·I Chip EMI Filter
Description
Features
The QPI-11 EMI filter is specifically designed to
attenuate conducted common-mode (CM) and
differential-mode (DM) noise of the VICOR V•I Chip
products to comply with the CISPR22 standard
requirements for conducted noise measurements. The
filter is designed to operate up to 36 Vdc and supports
7 A loads up to 60°C without derating.
• >50 dB CM attenuation at 1 MHz
Designed for the military and industrial bus range, the
V•I Chip EMI Filter supports the PICMG® 3.0
specification for filtering system boards to the EN55022
Class B limits.
• 12.4 x 25 x 4.5 mm SiP (System-in-a-Package)
• >70 dB DM attenuation at 1 MHz
• 50 Vdc (max input)
• 100 Vdc surge 100 ms
• 750 Vdc Hi-pot hold off to shield plane
• 7 A rating
• Low profile LGA package
• -40° to +100°C PCB temperature (see Figure 6)
• Efficiency >99%
Applications
• COTS Military and Industrial
• V•I Chip input power filter

When laying out the QPI-11L, care must be taken such that the input and output signal polygons do not overlap each other on lower layers.

QPI-11 PCB Layout Recommendations
Post Solder Cleaning
The filtering performance of the QPI-11 and –12 is
sensitive to capacitive coupling between its input and
output pins. Parasitic plane capacitance must be kept
below 1 pico-Farad between inputs and outputs using
the layout shown above and the recommendations
described below to achieve maximum conducted EMI
performance.
Picor lidded QP SIPs are not hermetically sealed and must
not be exposed to liquid, including but not limited to
cleaning solvents, aqueous washing solutions or
pressurized sprays.
To avoid capacitive coupling between input and output
pins, there should not be any planes or large traces
that run under both input and output pins, such as a
ground plane or power plane. For example, if there
are two signal planes or large traces where one trace
runs under the input pins, and the other under the
output pins, and both planes over lap in another area,
they will cause capacitive coupling between input and
output pins. Also, planes that run under both input
and outputs pins, but do not cross, can cause capacitive
coupling if they are capacitively by-passed together.
When soldering, it is recommended that no-clean flux
solder be used, as this will insure that potentially
corrosive mobile ions will not remain on, around, or
under the module following the soldering process.
For applications requiring water wash compatibility the
“–01” open frame version should be used.
Figure 5 shows the recommended pcb layout on a 2
layer board. Here, the top layer planes are duplicated
on the bottom layer so that there can be no overlapping of input and output planes. This method can
be used for boards of greater layer count.
