Note :1. All temperatures refer to topside of the package, measured on the package body surface.

2.For devices mounted on FR-4 PCB of 1.6mm or equivalent grade PCB. If other grade PCB is used, care

should be taken to match the coefficients of thermal expansion between components and PCB. If they are

not matched well, the solder joints may crack or the bodies of the parts may crack or shatter as the assembly

cools.
