1. SCOPE
1.1 Scope. This drawing describes the requirements for a 0.120 by 0.060 chip resistor, which is resistant to the
degrading effects of moisture while under power.
1.2 Part or Identifying Numbers (PIN’s). The complete PIN’s are shown in the examples below. The first example is for
general military applications. (NOTE: This PIN is the original PIN shown in previous revisions of this drawing). The
second example is for space type applications and requires adding a code letter to the end of the original PIN.
NOTE: Example of military level PIN.

Characteristic: "K"
Voltage rating: 100 volts (V)
V = .1 x V (for “R” ≥ critical res.)

4.5 Visual and mechanical examination. Resistors shall be examined to verify that the materials, design, construction,
physical dimensions, marking, and workmanship are in accordance with the applicable requirements of MIL-PRF-55342.
4.6 Data retention (codes A & T). Data retention for space level products shall be per the requirements of
MIL-PRF-55342.
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. Chip
resistors can also be used in 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 variables and attributes data that parts have
passed conformance inspection, with each shipment of parts by the manufacturer.
c. Packaging requirements (see 5.1).
d. Whether the manufacturer performs the group B inspection and the moisture resistance test or provides a
certificate of compliance (see 4.3.1.1, military level only).
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 of conditions, these resistors can be electrically damaged, by
electrostatic charges, and drift from specified value. Users should consider 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.
6.6 User of record. Coordination of this document for future revisions is coordinated only with the approved source of
supply and the users of record of this document. Requests to be added as a recorded user of this drawing may be
achieved online at [email protected] or in writing to: DLA Land and Maritime-VAT, Post Office Box 3990, Columbus, OH
