Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
1. FR−5 = 1.0 x 0.75 x 0.062 in.
(Note: Microdot may be in either location)
*Date Code orientation and/or overbar may
vary depending upon manufacturing location.
2. Alumina = 0.4 x 0.3 x 0.024 in. 99.5% alumina.
