3.3.2 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.

3.3.3. Resistance values not listed in the "10 to 100" decade table of MIL-PRF-55342 for the appropriate resistance
tolerance shall be considered as not conforming to the specification. The standard values for every decade shall follow
the sequence demonstrated for the "10 to 100" decade table specified in MIL-PRF-55342.

d. Operating conditions: Rated dc continuous working voltage or filtered, nonfiltered full-wave rectified ac voltage
shall be applied intermittently, 1 hour and 30 minutes “on”, and 30 minutes “off”, for the applicable number of
hours and applicable test temperature. "On time" shall be three quarters of the total elapsed time. During the

voltage.
e. Duration: 100 hours ±4 hours.
f. Stabilization and final dc resistance measurement: Resistors shall be removed from chambers for a minimum of
45 minutes and stabilized prior to final resistance measurement.
g. Examination after test: Resistors shall be examined for evidence of mechanical damage.
4.9 Solderability. Solderability shall be tested in accordance with MIL-PRF-55342 and 4.4.1.1.3 herein.
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, also,
for use in surfacing mounting 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. Packaging requirements.
d. Whether the manufacturer performs the group B tests or provides certification of compliance with group B
requirements (see 4.4.1.3).
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.
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: DSCC-VAT, Post Office Box 3990, Columbus, OH 43218-3990 or by

6.7 Approved source of supply. Approved source of supply is listed herein. Additional sources will be added as they
become available. Assistance in the use of this drawing may be obtained online at resistor@dla.mil or contact
