Notes:

1. Lead finish (A,C, or X) must be specified.

2. If an “X” is specified when ordering, part marking will match the lead finish and will be either “A” (solder) or “C” (gold).

3. Total dose radiation must be specified when ordering. QML Q and QML V not available without radiation hardening. For prototype inquiries, contact

factory.

4. Device type 02 is only offered with a TID tolerance guarantee of 3E5 rads(Si) or 1E6 rads(Si) and is tested in accordance with MIL-STD-883 Test

Method 1019 Condition A and section 3.11.2. Device type 03 is only offered with a TID tolerance guarantee of 1E5 rads(Si), 3E5 rads(Si), and 5E5

rads(Si), and is tested in accordance with MIL-STD-883 Test Method 1019 Condition A.
