For applications that require meeting EMC standards, the diagram above 5. Recommended values for components are: 7. The output fi ltering capacitor (C6) is a high frequency, low
illustrates a typical connection of the MD600xRW series. The units Component resistance electrolytic capacitor. Care must be taken in
do not require external components to operate as specifi ed. Some notes 5 VIN 12 VIN 24 VIN 48 VIN choosing this capacitor not to exceed the capacitive load
on this diagram (starting with the input circuit) are: C1 220 µF/25V specifi cation for the unit. Voltage derating of capacitors
1. An external fuse should be used in all power module applications. C2 22 µF/25V 10 µF/50V 10 µF/50V 2.2 µF/100V should be 80% or above
The recommended fuse is shown in the model chart on page 2. LDM1 10 µH 10 µH 10 µH 15 µH 8. The drawings below show typical board layouts for the EMI
2. To protect against a surge, an external MOV is recommended on the 22 µF/25V 10 µF/50V 10 µF/50V 2.2 µF/100V circuit shown above (one for single output models and one

be mounted as close to the converter as possible. 6. To meet the requirements of EN 61000-4-4 and EN 61000-4-5, an external input capacitor depending on the needs of the application. The output
is required for all models. The suggested value is 330 µF/100V. Contact the factory
capacitor would typically be 10 µF.
