Selected standard capacitor types, for use in the design and manufacturing of Department of Defense equipment under the jurisdiction of the Department of De

26、fense. b. Guides for the choice and application of capacitors for use in Department of Defense equipment. Requirements for capacitors listed in this handbook are covered in the applicable specification (see 2.1). When it has been determined that circuit requirements cannot be met by using capacitor

27、styles or characteristics listed in the applicable specifications, the design engineer should, with the approval of the cognizant activity, select from the applicable capacitor specification styles or characteristics not listed herein. 1.2 Purpose of handbook. a. To provide the equipment designer wi

28、th a selection of standard capacitors for use in most Department of Defense applications. b. To control and minimize the variety of capacitors used in Department of Defense equipment in order to facilitate logistic support of equipment in the field. c. To outline criteria pertaining to the use, choi

29、ce, and application of capacitors in Department of Defense equipment. 1.3 DLA Land and Maritime SpecFinder. DLA Land and Maritime Specfinder is an online tool that can be used in conjunction with this handbook. The SpecFinder is a search tool to help you find standardization documents by selecting d

A list of common terms used in

45、rating and design application of capacitors is as follows: a. Ambient temperature. Average or mean temperature of the medium (air, gas, liquid, etc.) surrounding an object. b. Anode. Positive electrode of a capacitor. c. Capacitance. Property of a capacitor which determines its ability to store elec

46、trical energy in “T” time when a given voltage is applied, measured in farads, microfarads, or picofarads. d. Capacitance tolerance. The part manufacturers guaranteed maximum deviation (expressed in percent) from the specified nominal value at standard (or stated) environmental conditions. e. Failur

47、e rate level (FRL). Denotes the maximum percentage of failures (per 1,000 unit hours) based on a specified level. f. Capacitive reactance. Opposition offered to the flow of an alternating or pulsating current by capacitance, measured in ohms. g. Capacitor. Electronic component part consisting essent

48、ially of two conducting surfaces separated by an insulating (dielectric) material. A capacitor stores electrical energy, blocks the flow of direct current, and permits the flow of alternating or pulsating current to a degree dependent on the capacitance dielectric and the frequency. (1) Capacitor, l

49、iquid-filled. A capacitor in which a liquid impregnant occupies substantially all of the case volume not required by the capacitor element and its connections. (Space may be allowed for the expansion of the liquid under temperature variations.) (2) Capacitor, liquid-impregnated. A capacitor in which a liquid impregnant is dominantly contained within the foil-
