20、rposes, 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 requir

21、ements are maintained by the Inventory Control Points packaging activity within the Military Service or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM p

22、roducts, 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 Notes The notes specified in MIL-PRF-55342 are applicable to this specification. 6.2 Acquisition requirements.

23、Acquisition documents should specify the following: a. Title, number, date of this specification, the applicable associated specification, and the complete PIN (see 1.2). * b. Unless otherwise specified (see 2.1), the versions of the individual documents referenced will be those in effect on the dat

24、e of release of the solicitation. c. Packaging requirements (see 5.1). (i.e. Electrostatic discharge (ESD) sensitive packaging). d. Allowable substitution (see MIL-PRF-55342). e. If marking is required (see MIL-PRF-55342). Provided by IHSNot for ResaleNo reproduction or networking permitted without

25、license from IHS-,-,-MIL-PRF-55342/12A w/ Amendment 3 5 6.3 Tolerance for wraparound termination. The added tolerance for the wraparound type termination is intended to apply only to termination, metallization, and pretinning material. 6.4 Electrostatic charge effects. Under relatively low humidity

26、conditions, some types of film resistors, particularly those with small dimensions and high sheet resistivity materials, are prone to sudden significant changes in resistance (usually reductions in value) and to changes in temperature coefficient of resistance as a result of discharge of static char

27、ges built up on associated objects during handling, packaging, or shipping. Substitution of more suitable implements and materials can help minimize this problem. For example, use of cotton gloves, static eliminator devices, air humidifiers, and operator and workbench grounding systems can reduce st

28、atic buildup during handling. Means of alleviating static problems during shipment include elimination of loose packaging of resistors and use of metal foil (conductive) and static dissipation packaging materials. Direct shipments to the government are controlled by MIL-DTL-39032 which specifies a p

29、reventive packaging procedure. * 6.5 Pulse applications. Designers are CAUTIONED on using these 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 five second short tim

30、e overload as part of the group B inspection of this specification. 6.6 Amendment notations. The margins of this specification are marked with asterisks to indicate modifications generated by this amendment. This was done as a convenience only and the Government assumes no liability whatsoever for a
