The four-digit resistance designation is applicable to all resistance tolerances. The nominal resistance is identified by four digits; the first three digits
12、 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 a fractional value of an ohm is required, the “R” will be substituted for one of the significant digits to represent the decimal point. When the lett
13、er “R” is used, succeeding digits of the group represent significant figures. The resistance values designations are shown in table I. Standard values for every decade will follow the sequence demonstrated for “10 to 100” decade in table II. Resistance values not listed in table II for the appropria
14、te resistance tolerance will be considered as not conforming to the specification. TABLE I.

For acquisition purpose, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging
44、 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 Points packaging activities within the Military Service or D

Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6. NOTES (This section contains information
46、 of a general or explanatory nature that 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 a
47、pplication. 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 a certificate of compliance that parts have passed conformance inspection with each shipment of parts by
48、 the manufacturer. c. Packaging requirements (see 5.1). (i.e. Electrostatic discharge sensitive packaging). d. Whether the manufacturer performs the group B tests or provides certificate of compliance with group B (see 4.2.1.2.1). 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
