For applications that require meeting higher EMC standards, the circuit shown above is recommended. Some notes

on this diagram (starting with the input circuit) are:

1. It is recommended that an external fuse be used. The recommended fuse is 1A/250V.

frequency, low ESR electrolytic capacitor. The recommended value is given in the table below.

high frequency electrolytic capacitors should be used. The recommended values are given in the table below.

The diagram above shows a typical board layout for the MPL-03SEUP with the recommended EMI components shown in the “Typical Connection 2” diagram. Filter modules are available from MPD. Contact the factory for more

information. To meet safety regulations, the board trace widths should be >3 mm, the distance between traces should be >6 mm, and the distance between traces and ground should be >6 mm. The distance “A” noted on the

drawing should be >6.4 mm.

The diagram above illustrates a typical connection of the MPL-03SEUP series. With this connection, the unit will meet EN 55022 class A, EN 61000-4-2 (±4kV), EN61000-4-4 (±2kV), EN 61000-4-8 and EN

values are given in the table below.

6. The output TVS will help protect system circuitry if power supply fails. A recommended value is given in

the table below.

8. All of the components within the dotted lines of the input EMC circuit are included in a filter module

available from MPD. Please contact the factory for more information.
