An LED is the device shown above. Besides red, they can also be yellow, green and blue. The letters LED stand for Light Emitting Diode.
Depicts the step-by-step process by which the transistors of an integrated circuit are made.
A reed switch is a switch which is operated by a magnetic field. Two fine contacts are contained within a glass tube and spaced so that there is only a very small gap between them.
and protection for tetrode amplifiers
certain electronic circuits require extremely low-noise power supplies and this circuit provides very good quality power output
100-mA regulator that uses a dual linear-regulator IC to produce output voltages below 1.25V from 2.9 to 5.5V input-voltage range
PC parallel port relay card
remote voltage sensing usually uses a four-wire sensing system, this system works with three wires.
Send power to a remote stepper motor and control its rotation and speed over only two wires
