Implementation・Mounting Method
Mounting method
¡The unit can be mounted in any direction. 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.
¡Avoid placing the signal line pattern layout underneath the unit because the power supply might become unstable. Lay out the pattern
away from the unit.
Stress to the pins
¡Applying excessive stress to the input or output pins of the power module may damage
internal connections. Avoid applying stress in excess of that shown in right figure.
Less than
19.6N(2kgf)
¡Input/output pin are soldered to the PCB internally. Do not pull or bend a lead powerfully.
¡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 sili-

19.6N(2kgf)

cone rubber, etc.
Soldering
¡Flow soldering: 260C for up to 15 seconds.
¡Soldering iron (26W): 450C for up to 5 seconds.
