For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packa

24、ging of material 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

25、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 products, or by contacting the responsible packaging activity. 6. NOTES (This section contains informa

26、tion of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Notes. The notes specified in MIL-PRF-55182 are applicable to this specification. 6.2 Acquisition requirements. Acquisition documents must specify the following: a. Title, number, and date of the specification. b

27、. Unless otherwise specified (see 2.1), the versions of the individual documents referenced will be those in effect on the date of release of the solicitation. c. Packaging requirements (see 5.1). (i.e. Electrostatic discharge (ESD) sensitive packaging). 6.3 Power rating at 70C. Resistors furnished

28、to this specification have completed 2,000 hours of testing at 70C and power rating of 2.0 watts; however, the failure rate level specified is established at 1 watt at 125C. User should consider the FR level as assigned only to the 125C temperature. * 6.4 Pulse applications. Designers are CAUTIONED

29、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. This resistor only sees a one hour overload (see paragraph 4.8.3 of MIL-PRF-55182) as part of the group A inspection of this spec

30、ification. Designers MAY CONSIDER using DLA Land and Maritime drawing 03006 for high power pulse applications. NOTE: This resistor does not have the geometry (form, fit) of the MIL-PRF-55182 resistor, nor are they subject to the same Qualification/verification, Conformance inspection, or Periodic Gr

31、oup C inspection requirements. 6.5 RNN terminal substitution. Due to the loss of the last source of supply for weldable RNN style resistors with characteristic H, J, and K, it is recommended instead to use the RNC style resistors with solderable/weldable terminals for equivalent characteristic, resi

32、stance value, tolerance, and product level. 6.6 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 ship

33、ment to the Government is controlled by MIL-DTL-39032 which specifies a preventive packaging procedure. * 6.7 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

34、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 tin containing 3 percent or more lead, by mass, have shown to i

35、nhibit the growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.8 Amendment notations. The margins of this specification are marked with asterisks to indicate modifications generated by this amendment.

36、This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations. Copyright Communicat
