Epoxy resin 42 alloy Solder plating (5m) 0.41 TYP. 4/Nov. 28, 1996
The surface mount type packages are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
