- *1 Consult us about dynamic load and input response. Measure the output voltage by using the average mode of the tester to deal with the burst operation at low (Io=0～20%typ) load. 

- *2 This is the result of measurement of the testing board with capacitors of 47μF and 0.1μF placed at 50 mm from the output terminals by a 20MHz oscilloscope or a ripple-noise meter equivalent to Keisoku-GikenRM104. 

   - When the load factor is low (Io=0~20%typ), the switching power loss is reduced by burst operation, which will cause ripple noise to go beyond the specifications. 

- *3 Output power derating is required. Refer to "Derating" 

   - *5 Please contact us about another class. When two or more units are operating it may not comply with the IEC61000-3-2. Please contact us for details. 

   - * All parameters not specially mentioned are measured at ACIN 230V, rated load and 25℃ of ambient temperature. 

   - Do not use the power supply in overcurrent conditions or in unspecified input voltage ranges. Otherwise the internal components may be damaged. 

   - * Parallel operation is not possible with this model. 

   - Acoustic noise may be heard from the power supply when used for pulse load. 

- *4 Consult us about details.

## **Implementation** ・ **Mounting Method** 

## Mounting method 

■AC voltage exists on the primary side. Therefore, in order to prevent electric shock, or to meet the leakage current requirements of the safety standard, you need to secure an insulation distance of at least 5mm. 

■ When two or more power supplies are used side by side, position them with proper intervals to allow enough air ventilation. The temperature around each power supply should not exceed the temperature range shown in derating curve.

■ Avoid placing the AC input line pattern layout underneath the unit.It will increase the line conducted noise. Make sure to leave an ample distance between the line pattern layout and the unit. Also avoid placing the DC output line pattern underneath the unit because it may increase the output noise. Lay out the pattern away from the unit.

## Soldering 

- Flow soldering: 260 C for up to 10 seconds. 

- Soldering iron (70W): 360 C for up to 5 seconds. 

## Stress to the pins 

- ■Input/output pin are soldered to the PCB internally.Do not pull or push a lead powerfully. 

- ■Applying excessive stress to the input or output pins of the unit may damage internal connections. Avoid applying stress in excess of that shown in the figure on the right. 

- If it is expected that stress is applied to the input/output pin due to vibration or impact, reduce the stress to the pin by taking such measures as fixing the unit to the PCB by silicone rubber, etc.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
