or a minimum of three evenly spaced contrasting color dots around the periphery of the cathode end may be used.
At the option of the manufacturer, URS devices may include laser marking on an end-cap, to include part number
and lot date code for all levels. The prefixes JAN, JANTX, or JANTXV may be abbreviated as J, JX, or JV,
respectively. (For example: The part number may be reduced to JV6469). All device marking, except for polarity
and serial numbers, shall also appear on the unit package used as the initial protection for delivery. No color coding
will be permitted.
3.5.2 URS polarity. For URS surface mount parts only, cathode shall be connected to the round end-cap.
3.6 Electrical performance characteristics. Unless otherwise specified, the electrical performance characteristics
3.7 Electrical test requirements. The electrical test requirements shall be the subgroups specified in table I

shall be free from other defects that will affect life, serviceability, or appearance.
4. VERIFICATION
4.1 Classification of inspection. The inspection requirements specified herein are classified as follows:
a.
Qualification inspection (see 4.2).
b.
Screening (see 4.3).
c.
4.2 Qualification inspection. Qualification inspection shall be in accordance with MIL-PRF-19500.
4.2.1 Group E qualification. Group E inspection shall be performed for qualification or re-qualification only. In
case qualification was awarded to a prior revision of the specification sheet that did not require the performance of
table IV tests, the tests specified in table IV herein that were not performed in the prior revision shall be performed
on the first inspection lot of this revision to maintain qualification.
4.3 Screening (JANTX and JANTXV levels only). Screening shall be in accordance with table E-IV of
MIL-PRF-19500, and as specified herein. The following measurements shall be made in accordance with table I
herein. Devices that exceed the limits of table I herein shall not be acceptable.
