When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the resp
21、onsible packaging activity to ascertain packaging requirements. Packaging requirements 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 mana
22、ging Military Departments or Defense Agencys 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 that may be helpful, but is not mandatory.) 6.1 Intended use. Chip resistors ar
23、e intended to be used in thin or thick film hybrid circuits where micro-circuitry is indicated and in surface mount applications. 6.2 Acquisition requirements. Acquisition documents should specify the following: a. Title, number, date of this specification, the applicable associated specification, a
24、nd 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 date of release of the solicitation. c. Packaging requirements (see 5.1). (i.e. Electrostatic discharge (ESD) sensitive packaging). d. Allowabl
25、e substitution (see MIL-PRF-55342). e. If marking is required (see MIL-PRF-55342). Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-55342/7E w/ Amendment 3 5 6.3 Tolerance for wraparound termination. The added tolerance for the wraparound type
26、 termination is intended to apply only to termination, metallization, and pretinning material. 6.4 Electrostatic charge effects. Under relatively low humidity conditions, some types of film resistors, particularly those with small dimensions and high sheet resistivity materials, are prone to sudden
27、significant changes in resistance (usually reductions in value) and to changes in temperature coefficient of resistance as a result of discharge of static charges built up on associated objects during handling, packaging, or shipping. Substitution of more suitable implements and materials can help m
28、inimize this problem. For example, use of cotton gloves, static eliminator devices, air humidifiers, and operator and workbench grounding systems can reduce static buildup during handling. Means of alleviating static problems during shipment include elimination of loose packaging of resistors and us
29、e of metal foil (conductive) and static dissipation packaging materials. Direct shipments to the government are controlled by MIL-DTL-39032 which specifies a preventive packaging procedure. * 6.5 Pulse applications. Designers are CAUTIONED on using these resistors in high power pulse applications. S
30、ince they have not been qualified nor tested for such applications, damage and premature failure are possible. These resistors only see a five second short time overload as part of the group B inspection of this specification. 6.6 Amendment notations. The margins of this specification are marked wit
31、h asterisks to indicate modifications generated by this amendment. 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 c
