3.3 Electrical characteristics.
3.3.1 Temperature range. The temperature range shall be –55°C to +125°C.
3.3.2 Resistance. The resistance shall not exceed 0.03 ohm.
*
3.3.3 Termination. Termination material shall be in accordance with MIL-PRF-32159, code letter B.
3.4 Marking. Marking of the individual chip resistors is not required; however, each unit package shall be marked in
accordance with MIL-STD-1285 and include the PIN as specified herein (see 1.2), the manufacturers name or Commercial
and Government Entity (CAGE) code, and date lot codes.
*
3.5 Recycled, recovered, environmentally preferable, or biobased materials. Recycled, recovered, environmentally
preferable, or biobased 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.
*
3.6 Manufacturer eligibility. To be eligible for listing as an approved source of supply, a manufacturer shall be listed on
the MIL-PRF-32159 Qualified Products List for at least one part, or perform the group A and group B inspections specified
herein on a sample agreed upon by the manufacturer and DLA Land and Maritime-VAT.
*
3.6.1 Certificate of compliance. A certificate of compliance shall be required from manufacturers requesting to be listed
as an approved source of supply.
3.7 Workmanship. Resistors shall be uniform in quality and free from any defects that will affect life, serviceability, or
appearance.
4. VERIFICATION
*
4.1 Product assurance program. The product assurance program specified in MIL-PRF-32159 and maintained in
accordance with MIL-STD-790 is not applicable to this document.
4.2 Qualification inspection. Qualification inspection is not applicable to this document.
*
4.3 Product level qualification. The product level qualification specified in MIL-PRF-32159 is not applicable to this
document.
4.4 Conformance inspection.
*
4.4.1 Inspection of product for delivery. Inspection of product for delivery shall consist of group A inspection (established
reliability level only and the parts per million reporting is not applicable) of MIL-PRF-32159.
*
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-32159.
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 requisite requirements. Packaging requirements are maintained
by the Inventory Control Point's packaging activities within the Military Service or Defense Agency, or within the Military
Services System Command. 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 which 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. Resistors
are also for use 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 data or certificate of compliance that parts
have passed conformance inspection with each shipment of parts by the manufacturer.
c. Requirements for packaging and packing.
*
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 onetime pulse (Short-time overload) as part of the group B inspection of MIL-PRF-32159.
*
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 resistor@dla.mil or in writing to: DLA Land and Maritime, Attn: VAT, Post Office Box 3990, Columbus,
OH 43218-3990 or by telephone (614) 692-0552 or DSN 850-0552.
