Special Features:

Items are being coded as critical to insure source inspection will be performed at the point of manufacture, prior to material receipt by the us navy or other dod components. These items are piece parts or end items in support of vital military hardware necessary to sustain the successful mission of the ships, submarines, and shore stations of the us navy. Critical features including, but not limited to, dimensions, tolerances/clearances, electronic characteristics, and metallurgical properties will bespecified for government q ar (quality assurance representatives) to insure the highest possible degree of quality and reliability of these parts being delivered under navicp contracts

Properties:

An electromechanical device which uses a coil operated switching mechanism to convert a direct current input into a pulsating direct current output of the same value. The direct current input is periodically interrupted at the resonant frequency of a coil driven vibrating armature (reed). The resultant pulsating direct current output produces an inherent alternating current component necessary for ultimate purposes of transformation. It does not include a means of amplification or rectification. For items designed to operate over a wide and comparatively high frequency range and whose drive coil may be excited from either an alternating current or a direct current, see chopper, electronic.
