Notes:
1. Lead finish (A,C, or X) must be specified.
2. If an “X” is specified when ordering, then the part marking will match the lead finish and will be either “A” (solder) or “C” (gold).
3. Military Temperature Range flow per UTMC Manufacturing Flows Document. Radiation characteristics are neither tested nor guaranteed and may
not be specified.
4. Prototypes are produced to UTMC’s prototype flow and are tested at 25°C only. Radiation characteristics are neither tested nor guaranteed. Lead finish
is GOLD only.
