  2. Fibre Channel electrical interface - Wikipedia

    en.wikipedia.org/wiki/Fibre_Channel_electrical...

    In simple terms, the transmitter circuit must output a signal with a minimum of 600 mV peak-to-peak differential, maximum 2000 mV peak-to-peak differential. A good signal looks rather like a sine-wave with a fundamental frequency of half the data rate, so 1 GHz for a typical system running at 2 gigabits per second.

  3. LED circuit - Wikipedia

    en.wikipedia.org/wiki/LED_circuit

    In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED. The voltage drop across a lit LED is approximately constant over a wide range of operating

    Separable assembly or sub-assembly (e.g. printed circuit assembly) AT: Attenuator or isolator: BR: Bridge rectifier (four diodes in a package) often changed to "D" for diode BT, BAT: Battery or battery holder: often shortened to "B" C: Capacitor: CB: Circuit breaker: CN: Capacitor network: may be simplified to "C" for capacitor D, CR: Diode ...

  5. Circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Circuit_breaker

    A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire.

  6. ANSI device numbers - Wikipedia

    en.wikipedia.org/wiki/ANSI_device_numbers

    In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI / IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations .

  7. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...

  8. Power supply - Wikipedia

    en.wikipedia.org/wiki/Power_supply

    An integrated power supply is one that shares a common printed circuit board with its load. An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics ...

  9. IC power-supply pin - Wikipedia

    This led to V D and V S being created by supply voltages designated V DD and V SS in the more common circuit configurations. In equivalence to the difference between NPN and PNP bipolars, V DD is positive with regard to V SS in the case of n -channel FETs and MOSFETs and negative for circuits based on p -channel FETs and MOSFETs.
