DESCRIPTION
microseconds. The damping circuit can be used with a 1.50 Ω
resistor in series with the filter’s positive input where the additional
line loss can be tolerated. For transients with rise times of greater
than 200 microseconds, there is no overshoot and the damping
circuit is not required.
Interpoint’s surface mount FMGA-461™ EMI filter has been
designed to work with Interpoint’s surface mount MGA and MGH
Series DC/DC converters. Multiple MGA or MGH Series converters
can be operated from a single FMGA filter provided the total power
line current does not exceed the filter’s maximum rating. The FMGA
filter will reduce the converter’s power line reflected ripple current to
within the limit of MIL-STD-461C, Method CE03 as shown in Figures
4 through 7. The filter uses only ceramic capacitors for reliable high-
temperature operation.
SURFACE MOUNT PACKAGE
The FMGA EMI filter can be surface mounted with pick-and-place
equipment or manually. It is recommended that the case be
attached with flexible epoxy adhesive or silicone which is thermally
conductive (>1 watt /meter/°K).
CONNECTION AND OPERATION
Where more than one pin has the same designation (e.g. pins 7, 8,
and 9 are Positive Output), all of those pins must be connected for
output performance to meet the specifications.
Internal components are soldered with SN96 (melting temperature
221°C) to prevent damage during reflow. Maximum reflow tempera-
ture for surface mounting the FMGA filter is 220°C for a maximum
of 30 seconds. SN60, 62, or 63 are the recommended types of
solder. Hand soldering should not exceed 300°C for 10 seconds per
pin.
The MGA Series has an internal 2 µF capacitor its input terminals
and the MGH Series has an internal 0.47 µF capacitor across its
input power terminals. When the MGA or MGH converters are used
with the FMGA filter, this capacitor becomes part of the filter and
forms its final LC output section. When 2 or 3 MGA or MGH
converters are used with a single filter, this capacitor becomes
larger, improving the rejection versus frequency.
The hermetically sealed metal cases are available in two different
lead configurations. See Section B8, case B.
LAYOUT REQUIREMENTS
The case of the filter must be connected to the case of the converter
through a low impedance connection to minimize EMI.
TRANSIENT DAMPING
The optional damping circuit shown in Figure 2 will prevent filter
overshoot caused by 80 V transients with rise times of less than 200

The case ground connection between the filter and the converter should be as low an impedance as possible
to minimize EMI. Direct contact of baseplate to chassis ground provides the lowest impedance.

1. Pad dimensions are for the solder mask opening. Lead common to
each other can be connected underneath as desired.
2. Ground pins should be connected to the center pad for improved
grounding.
0.060 (1.52)
0.870 (22.10)
0.030 (0.76)
3. Center pad should not have a solder mask. Solder, copper, or Au/Ni
plate are preferred over solder for adhesive attach.
4. Solder coat to solder down converter.
5. If less rotation of case is desired, make the pad width 0.020inches
(0.51 mm). Pad length can be extended 0.010 inches (0.25 mm)
towards the case body and as-desired dimension away from the case
body.
6. Do not exceed 220°C as measured on the body of the converter (top
or bottom).
7. Attach the body of the case to the board with a thermally conductive
adhesive or SN60, 62, or 63 solder. The adhesive can be electrically
conductive as well. It can be applied as an underfill post solder or
dispensed and cured prior or during solder.
