Delphi Series Filter Module - FL75L05 A
75Vdc input, 5A current Rating
The Delphi series FL75L05 A filter module is the latest offering from a
world leader in power systems technology and manufacturing – Delta
Electronics, Inc. This filter module is designed to reduce the conducted
common-mode and differential-mode noise on input or output lines of
high-frequency switching power supplies and has a maximum current
rating of 5A. It has the industry standard footprint and pin-out. With
creative design technology and optimization of component placement,
Delphi FL75L05 A filter module possesses outstanding electrical and
thermal performance, as well as extremely high reliability under highly
stressful operating conditions.

THERMAL CURVES
Thermal management is an important part of the system
design. To ensure proper, reliable operation, sufficient
cooling of the power module is needed over the entire
temperature range of the module. Convection cooling is
usually the dominant mode of heat transfer.
OUT
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.
OUT
Thermal Testing Setup
Delta’s filter modules are characterized in heated
vertical wind tunnels that simulate the thermal
environments encountered in most electronics
equipment. This type of equipment commonly uses
vertically mounted circuit cards in cabinet racks in which
the power modules are mounted.
The following figure shows the wind tunnel
characterization setup. The filter module is mounted on
a test PWB and is vertically positioned within the wind
tunnel. The space between the neighboring PWB and
the top of the power module is 6.35mm (0.25”).

Heat can be removed by increasing airflow over the
module. Figure 4 shows maximum output is a function of
ambient temperature and airflow rate. To enhance system
reliability, the power module should always be operated
below the maximum operating temperature. If the
temperature exceeds the maximum module temperature,
reliability of the unit may be affected.

APPLICATION
Note: C2 through C5 can be 0.01μF to o.1μF. Select the voltage rating to meet input-to-output isolation requirements. C1 should be the recommended
value indicated in the power module data sheet.
Figure 7. Recommended schematic when used as the input filter to a high-frequency dc-to-dc converter
Note: Vdc input(+) and Vdc input(-) planes should overlay each other, as should the Vi(+) and Vi(-) planes, as should the Vout(+) and Vout(-) planes. Avoid
routing signals or planes under the power module or the filter module. Ensure all connections are low impedance.

APPLICATION (Continued)
Note: : C2 through C5 and C6 through C9 can be 0.01μF to o.1μF. Select the voltage rating to meet input-to-output isolation requirements. C1 should be
the recommended value indicated in the power module datasheet.

Figure 10 shows the experimental result obtained by using this filter module, together with the recommended external
components shown in Figures 5 and 6. The Q48SR3R335NR module is one of the Delphi series quarter brick 3.3V, 35A
DCDC converters. Measured noise is greatly dependent on layout, grounding, cable orientation, and load characteristics
and the variation is possible from various application conditions.
