All limits are ensured at room temperature (standard type face) and at
temperature extremes (bold type face).
All room temperature
limits are 100% tested during production with T
A
= T
J
= 25°C. All limits at temperature extremes are ensured via correlation using
standard Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
