All limits are specified at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits

are 100% tested through statistical analysis. All limits at temperature extremes via correlation using standard Statistical Quality Control

(SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).

(2)

Typical numbers are at 25°C and represent the expected value of the parameter.
