Soldering Information - Hole Mounting
The hole mounted product is intended for plated through
hole mounting by wave or manual soldering. The pin
temperature is specified to maximum to 270°C for
maximum 10 seconds.
A maximum preheat rate of 4°C/s and maximum preheat
temperature of 150°C is suggested. When soldering by
hand, care should be taken to avoid direct contact between
the hot soldering iron tip and the pins for more than a few
seconds in order to prevent overheating.
A no-clean flux is recommended to avoid entrapment of
cleaning fluids in cavities inside the product or between
the product and the host board. The cleaning residues may
affect long time reliability and isolation voltage.
Delivery Package Information
The products are delivered in antistatic injection molded
trays (Jedec design guide 4.10D standard) and in antistatic
