microelement

[¦mī·krō′el·ə·mənt]
(electronics)
Resistor, capacitor, transistor, diode, inductor, transformer, or other electronic element or combination of elements mounted on a ceramic wafer 0.025 centimeter thick and about 0.75 centimeter square; individual microelements are stacked, interconnected, and potted to form micromodules.
(industrial engineering)
An element of a work cycle whose time span is too short to be observed by the unaided eye.
