Delphi Series Filter Module - FL75L07

0~75Vdc input, 7A Current Rating

The Delphi series FL75L07 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 o

high-frequency switching power supplies and has a maximum curren

rating of 7A. It has the industry standard footprint and pin-out. With

creative design technology and optimization of component placement,

Delphi FL75L07 filter module possesses outstanding electrical and

thermal performance, as well as extremely high reliability under highl

stressful operating conditions.

THERMAL CONSIDERATIONS

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.

Hence, the choice of equipment to characterize the

thermal performance of the power module is a wind

tunnel.

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”).

Thermal Derating

Heat can be removed by increasing airflow over the

module. Figure 4 show s 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 af fected.

APPLICATION

Note: C2 & C3 can be 0.01μF to 0.1μF. Select the voltage rating to meet input-to-output isolation requirements. C1 should be the recommended value

suggested in the power module data sheet.

Figure 12 shows the experimental result obtained by using this filter module, together with the recommended external

components shown in Figures 7 and 8. The Q48SB12025NR A module is one of the Delphi series quarter brick 12V, 25A

DCDC converters. Measured noise is greatly dependent on layout, grounding, cable orientation, and load characteristics

and the variation is possible from variou s application conditions.

Note: Inside this filter module, the components have no

voltage polarity. Hence, the input positive (Vin+) and input

negative (Vin-) labels could be swaped for the

convenience of layout and matching with power module

input connected to the filter module, just remember to

swap the output labels accordingly as well. Please refer to

Figures 8 and 10 for how it is applied.
