3.1 Item requirements. The individual item requirements shall be in accordance with MIL-PRF-83401, and as specified
herein.
3.2 Interface and physical dimensions. Resistors shall meet the interface and physical dimensions as specified
herein (see figure 1).
3.3 Electrical characteristics.
3.3.1 Resistance. The nominal resistance is expressed in ohms and is identified by four digits. The first three digits
represent the significant figures and the last digit specifies the number of zeros to follow. When the value of the

3.7 Marking. Marking is not required on the resistor; however, each unit package shall be marked with the PIN
assigned herein (see 1.2), vendor CAGE code, and date and lot codes.
3.8 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable
materials should be used to the maximum extent possible provided that the material meets or exceeds the operational
and maintenance requirements, and promotes economically advantageous life cycle costs.
3.9 Certificate of compliance. A certificate of compliance shall be required from manufacturers requesting to be a
suggested source of supply.
3.10 Workmanship. The resistor shall be uniform in quality and free from any defects that will affect life, serviceability,
or appearance.
4. VERIFICATION
4.1 Qualification inspection. Qualification inspection is not applicable to this document.
4.2 Conformance inspection.
4.2.1 Inspection of product for delivery. Inspection of product for delivery shall consist of group A inspection (M level
part) and group B inspection of MIL-PRF-83401. Additionally; a power moisture resistance test as specified in 4.3 shall
be performed.
4.2.2 Certification. The acquiring activity may accept a certificate of compliance in lieu of performing group B
inspection and the power moisture resistance test.
4.3 Moisture resistance. Resistor networks shall be tested in accordance with MIL-PRF-83401. The following details
and exceptions shall apply:
a. The test is to be performed on an annual basis.
b. A 30 piece sample shall be used with 0 defects allowed.
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 activity within the Military Department 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. Surface mount resistors are used in electronic circuits where space is a major concern.
6.2 Ordering data. The contract or purchase order should specify the following:
a. Complete PIN (see 1.2).
b. Requirements for delivery and 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 inspection and the moisture resistance test or provides a
certificate of compliance (see 4.2.2).

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 User of record. Coordination of this document for future revisions is coordinated only with the suggested source of
supply and the users of record of this document. Requests to be added as a recorded user of this drawing may be
