1. SCOPE
1.1 Scope. This drawing documents five product assurance classes, class D (lowest reliability), class E, (exceptions), class G
(lowest high reliability), class H (high reliability), and class K, (highest reliability) and a choice of case outlines and lead finishes
are available and are reflected in the Part or Identifying Number (PIN). When available, a choice of radiation hardness
assurance levels are reflected in the PIN.
1.2 PIN. The PIN shall be as shown in the following example:
