Soldering Position A 50 A : Make sure the distance is 0.1 mm or more. 2. Solder Temperature and Soldering Time Temperature : 260C or less Time : within 3 seconds Note) Avoid using reflow soldering methods. 3. Other Issues 1) Soldering should not create excessive thermal or mechanical stress on the case package or leads. Excessive stress may cause changes in the shape or characteristics of the package or leads. 2) Be careful not to allow solder, flux, solvents, etc. to remain on the case package. Doing so may cause problems related to transmission characteristics, etc. Important Information Related to Power Source Voltage In order to stabilize the power line, use a decoupling capacitor of approximately 0.1 F between VCC and the GND line near the device .
