Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
A transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics. [1] It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit.
The British decimal one penny (1p) coin is a unit of currency and denomination of sterling coinage worth 1 ⁄ 100 of one pound.Its obverse featured the profile of Queen Elizabeth II since the coin's introduction on 15 February 1971, the day British currency was decimalised, until her death on 8 September 2022.

Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
Very small (1.6×1.6×0.35 mm) red, green, and blue surface mount miniature LED package with gold wire bonding details. These are mostly single-die LEDs used as indicators, and they come in various sizes from 1.8 mm to 10 mm, through-hole and surface mount packages. [47] Typical current ratings range from around 1 mA to above 20 mA.
The main parts were 40 panels and three portable function tables (named A, B, and C). The layout of the panels was (clockwise, starting with the left wall): Left wall. Initiating Unit; Cycling Unit; Master Programmer – panel 1 and 2; Function Table 1 – panel 1 and 2; Accumulator 1; Accumulator 2; Divider and Square Rooter; Accumulator 3 ...
The Webb telescope uses 132 small actuation motors to position and adjust the optics. [39] The actuators can position the mirror with 10 nanometer accuracy. [40] Webb's optical design is a three-mirror anastigmat, [41] which makes use of curved secondary and tertiary mirrors to deliver images that are free from optical aberrations over a wide ...
