EMC parameter recommendation :
Hlk-URB4815YMD-20WR3 48V to 15V 20W 1333mA DC to DC power supply has
| Component No. | Function | Recommended value |
| Fuse | Protest the circuit from damage when the module is abnormal | Access the corresponding fuse accrding to customer needs |
| MOV/Varistor | Protest the circuit from damage when the module is abnormal | 14D560K |
| LDM1/Common mode inductance | EMI Filtering | Inductance: 10mH |
| CO,C1 Ceramic capacitors | Filter capacitor | 1uF/50V |
| E1,E2 Electrolytic capacitor | Filter capacitor | 100uF/50V |
| LDM2/Differential mode inductance | EMI filtering | 4.7-68uH |
| CY1/Y2 Capacitance | 1nF/250vAC |
Notes：
* Fuses and varistors are basic parts of protection circuits (required).
* If the certification is required, the safety capacitor and common mode inductance cannot be omitted.
Output filtering :
For usual requirements of ripple and noise, the peripheral recommendation is only C2;
For strict requirements of ripple and noise, the above circuit is recommended. Notes:
(1) C2, C3 use high frequency low resistance electrolytic capacitor, and the total capacity can not exceed the maximum capacitive load indicated in the manual, otherwise the module will not start normally. (2) When the capacitive load is used, the minimum load of 3% must be guaranteed, otherwise the module output will be abnormal.
