  1. BC547 Transistor
  2. BC547 Transistor pinout

    BC547 Transistor(NPN)

    BC547 is an NPN transistor so when the base pin is grounded the collector and emitter will be open (reverse biased) and when a signal is applied to the base pin it will be closed (forward biased).

    BC547 Transistor Features

    1. Bi-Polar NPN Transistor
    2. BC547 Transistor
    3. Continuous Collector current (IC) is 100mA
    4. Emitter Base Voltage (VBE) is 6V
    5. Base Current(IB) is 5mA maximum
    6. DC Current Gain (hFE) is 800 maximum
    7. BC547 as Switch
    8. BC547 as Amplifier

  3. 1K ohm Resistor
  4. Resistor

    A Resistor is an electrical component that controls the flow of electricity in an electrical circuit. Or we can say in this way that the material or component That is used to block the flow of current in electronic equipment is called a Resistor. And, because of the characteristic of the resistor or conductor that Prevents the flow of current through the conductor, that characteristic or religion is called resistance, where resistance Means the ability to block. The main function of a resistor is to cause a voltage drop to impede the flow of current in the circuit. In this case, the question may arise as to which circuit or which Parts need to be protected from low voltage or current flow.

  5. 1n4007 Diode
  6. 1N4007 diode

    Diodes are used to protect circuits by limiting the voltage and also transform AC into DC. Semiconductors like silicon and germanium are used to make the most of the diodes.

    1N4007 is a rectifier diode, designed specifically for circuits that need to convert alternating current to direct current. It can pass currents of up to 1A and have a peak inverse voltage (PIV) rating of 1,000 V.

  7. 3mm LED
  8. Green LEDRed LED

    Light Emitting Diode (LED) Indicator lamps are a type of LED (Light Emitting Diode) lamp used to Display When a Change Occurs in an Electrical Circuit. When Something has Malfunctioned in an Electrical System, a red or Orange Light light-emitting diode Indicator Lamp may be used to alert a Worker. LED Indicator Lamps Usually consist of a single Bulb. Pilot lights and Light Emitting Diode indicator lights Indicate Lights for Machines or Instruments and they can also be built into Switches. They Provide Solutions for a Variety of Requirements and Are ideal for Highly Reliable Indications.
