MIL-HDBK-773 Electrostatic Discharge Protective PackagingThis handbook provides detailed guidance for DoD personnel who use, handle, package, or store Electrostatic Discharge Sensitive ESDS items. It is designed to promote the use of standardized packaging materials as well as promote an understanding of the Electrostatic Discharge ESD threat through all levels of maintenance and supply. This handbook is for guidance only and cannot be cited as a requirement.

MIL-HDBK-773A

4.4.1  Special protective devices.  The requirements for the use of special protective devices prior to packaging, as with shunting bars, clips, or non-corrosive conductive foams for protection, is the responsibility of the Government activity involved in item acquisition.  MIL-HDBK-263 and MIL-PRF-87893 provides further guidance in this area.

4.5  U.S. Air Force.  U.S. Air Force activities have been instructed to utilize ANSI/ESD S20.20 instead of MIL-STD-1686 and  ANSI/ESD S541 instead of MIL-HDBK-263.

5.  DETAILED GUIDANCE

5.1  Identifying ESDS items.  Due to the tremendous volume of electronic parts presently used by the military and the methods needed to accomplish the task, identifying parts that are ESDS is essential.  ESDS items are categorized as follows:

a.  The FEDLOG Army Master Data File (AMDF) Response for National Stock Numbers (NSNs) contains a data field identified as "ESDC" (Electrostatic Discharge Code).  This is a one character alpha code (for example, A, B, C, or D) that indicates whether an item is susceptible to ESD or electromagnetic interference damage.  If there is not a code in this field, do not assume that item is not ESDS.  All owners of ESDS items have not entered a code in this FEDLOG AMDF data field.

b.  If the letters "GX" are displayed in the MOP (Method of Preservation) field in an NSNs FEDLOG AMDF Packaging Data Response File, it is an ESDS item (see

MIL-STD-2073-1, Appendix J, table J.Ia, Specialized preservation codes).

c.  All printed circuit cards and wiring boards with mounted ESDS components. d.  All parts with Federal Supply Class (FSC) 5962.

e.  The U.S. Army Aviation and Missile Command has identified FSCs 5955, Oscillators and Piezoelectric Crystals, 5963, Electronic Modules, and 7042, Mini and Microcomputer Control Devices as ESDS items.

f.  The Defense Electronic Supply Center has identified specific resistors and semiconductors listed below as ESDS items.
