4.4.1.1.1 Subgroup 1. Subgroup 1 tests shall be performed on a production lot basis on 100 percent of the product
supplied under this document. Resistors that are out of resistance tolerance, or which experience a change in resistance
greater than that permitted for the tests of this subgroup shall be removed from the lot. Lots having more than 5 percent
total rejects, due to exceeding the specified resistance tolerance change limit shall not be furnished on contracts.

requirements in lieu of performing group B tests (see 6.2d).

5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see
6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to
contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained
by the Inventory Control Point's packaging activities within the Military Service or Defense Agency, or within the military
service's system commands. Packaging data retrieval is available from the managing Military Department's or Defense
Agency's automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)
6.1 Intended use. Chip resistors are intended for use in thick or thin film circuits where microcircuitry is intended, also
in most surface mount applications.
6.2 Ordering data. The contract or purchase order should specify the following:
a. Complete PIN (see 1.2).
b. Requirements for delivery: One copy of the conformance inspection data or certification of compliance that parts
have passed conformance inspection with each shipment of parts by the manufacturer.
c. Requirements for packaging and packing.
d. Whether the manufacturer performs the group B tests or provides certification of compliance with group B
requirements (see 4.4.2.1).

6.3 Tin whisker growth. The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker
growth problems after manufacture. Tin whiskers may occur anytime from a day to years after manufacture and can
develop under typical operating conditions, on products that use such materials. Conformal coatings applied over top of a
whisker-prone surface will not prevent the formation of tin whiskers. Alloys of 3 percent lead, by mass, have shown to
inhibit the growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification
for Electrodeposited Coatings of Tin).
*
6.4 Electrostatic charge. Under several combinations, these resistors can be electrically damaged, by electrostatic
charges, and drift from specified value. Users should be considered this phenomena when ordering or shipping resistors.
Direct shipment to the Government is controlled by MIL-DTL-39032 which specifies a preventive packaging procedure.
*
6.5 Pulse applications. Designers are CAUTIONED on using the above resistors in high power pulse applications.
Since they have not been qualified nor tested for such applications, damage and premature failure are possible. These
resistors only see a one time pulse (Short-time overload) as part of the group B inspection of MIL-PRF-55342.
