DEVICE MARKING INFORMATION
See specific marking information in the device marking column of the Electrical Characteristics table on page 2 of this data sheet.
Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. Nonrepetitive current pulse per Figure 9. 2. FR-5 = 1.0 X 0.75 X 0.62 in. 3. Alumina = 0.4 X 0.3 X 0.024 in, 99.5% alumina.
