  4. MJE13003 Transistor pinout

    This is an NPN transistor. Features: High voltage capability, Low spread of dynamic parameters, Very high switching speed and Applications: Electronic ballast for fluorescent lighting (CFL), SMPS for battery charger

  5. 1uf,50V Capacitor
  6. Capacitor,50V,1uf

    The capacitor is a Two-Terminal passive component having the Property of Capacitance. This Property Electrifies (charging with electricity) Capacitors with input Voltage. Capacitors Condense Electricity, Hence it is also known as a Condenser. It consists of two Electrical Conductors that are Separated by Distance. The Capacitor Stores Charge and can act like a Battery. It is necessary for filter Circuits to Minimize voltage spikes, and Smoothing changes in voltage.

  7. 10k Variable Resistor
  8. Variable Resistor 10k

    A variable resistor typically has three terminals: two fixed terminals at the ends of the resistive track and one movable terminal (the wiper). Depending on how the terminals are connected to a circuit, a variable resistor can function as a rheostat or a potentiometer.A resistor of which the ohmic resistance value can be adjusted. Either mechanically (potentiometer, rheostat) or electronically (digital potentiometer). A variable resistor is a resistor for which the electric resistance value can be adjusted. A variable resistor is in essence an electro-mechanical transducer and normally works by sliding a contact (wiper) over a resistive element. When a variable resistor is used as a potential divider by using 3 terminals it is called a potentiometer.
