If  the three coils from this component are going to be connected to a common GND; pins 1, 7 and 8 should be the chosen ones as common connection in order to keep the electromagnetic characteristics of the part.

Recommended reflow profile.


Reflow soldering, vapour-phase soldering. A maximum soldering temperature of 260ºC during 10 s should not be exceed for (see recommended soldering profile with maximum and minimum temperature-time).



The reflow condition recommended is according to the machine used by our company. Big differences will arise as a result of the type of machine, reflow conditions, method, etc used.
