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.

2. The NTC helps to prevent damage to the module in case an input current surge occurs. The recommended value

is given in the table below.

3. The MOV helps to prevent damage to the module in case an input voltage surge occurs. The recommended value

is given in the table below.

4. Capacitors C1, C2, C3 and C4 are input ﬁlter components (connected in series to achieve the required capacitance

level). Resistors R1, R2, R3 and R4 help to balance the current across the capacitors.

This diagram illustrates a typical board

layout for the MPV0560S-xxRHI or

MPV1060S-xxRHI with the recom-

mended EMI components shown in

the“Typical Connection 2”diagram.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. Contact the

factory for more information.

The diagram at left illustrates a typical connection of the

MPV0560S-xxRHI or MPV1060S-xxRHI series. Output

capacitors C6 and C5 are ﬁltering components. They

are required to meet ripple and noise speciﬁcations.

The recommended input components are a fuse, NTC,

and MOV. The recommended component values for

these are given in the table below.

6. Capacitor C5 is ceramic. This capacitor is used to ﬁlter high frequency noise. A recommended value is

given in the table below.

7. Capacitor C6 is an electrolytic. A low ESR, high frequency capacitor should be used. The recommended

value is given in the table below.

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

the table below.

9. Derating on all capacitors should be 80% or more.
