3.3 Electrical characteristics.
3.3.1 Resistance. The nominal resistance expressed in ohms is identified by four digits; the first three digits represent
significant figures and the last digit specifies the number of zeros to follow. When the value of resistance is less than 100
ohms, or when fractional values of an ohm are required, the letter "R" shall be substituted for one of the significant figures.
Minimum and maximum resistance values shall be as specified in 3.3.2. Resistance values not listed in the "10 to 100"
decade table (see table I) for the appropriate resistance tolerance shall be considered nonconforming to the specification.
3.3.2 Resistance range. Minimum and maximum resistance values for temperature characteristics of ±100 parts per
million (ppm) and ±350 ppm shall be as follows:
Minimum resistance
Maximum resistance
100 ppm
10 ohms

3.3.6.1 Pure tin. The use of pure tin, as an underplate or final finish is prohibited both internally and externally. Tin
content of resistor components and solder shall not exceed 97 percent, by mass. Tin shall be alloyed with a minimum of 3
percent lead, by mass (see 6.3).
3.3.7 Solderability. The requirement for solderability shall be as specified in MIL-PRF-39017.
3.4 Marking. Marking shall be in accordance with MIL-STD-1285, except the resistors shall be marked with the PIN as
specified herein (see 1.2), the manufacturer’s name or Commercial and Government Entity (CAGE) code, and date lot
codes.
3.5 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.
*
3.6 Manufacturer eligibility. To be eligible for listing as an approved source of supply, a manufacturer shall be listed on
the MIL-PRF-39017 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-VA.
*
3.6.1 Certificate of compliance. A certificate of compliance shall be required from manufacturers requesting to be an
approved source of supply.
3.7 Workmanship. Resistors shall be processed in such a manner as to be uniform in quality and parts shall be 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-39017 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 Failure rate qualification. The failure rate qualification specified in MIL-PRF-39017 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 the group A and group B
inspections of MIL-PRF-39017 where applicable.
4.4.2 Group B inspection. Group B inspection shall be in accordance with MIL-PRF-39017.
4.4.2.1 Certification. The acquiring activity, at its discretion, may accept a certificate of compliance with group B
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 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 which may be helpful, but is not mandatory.)
6.1 Intended use. Resistors conforming to this drawing are intended for use when military specifications do not exist
and qualified military devices that will perform the required function are not available for the OEM application.
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 a certificate of compliance with group B
requirements. If purchase order makes no reference to Group B screening the manufacturer will provide a
certification of compliance (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 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-39017.
*
6.5 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
