4700uF 25V Electrolytic Capacitor A 4700uF (microfarad) 25V electrolytic capacitor is a type of passive electronic component that stores electrical charge and is commonly used in electronic circuits for filtering, decoupling, and energy storage. It is called an electrolytic capacitor because it uses an electrolyte solution to store charge, which allows it to have a much higher capacitance than other types of capacitors. The voltage rating of 25V indicates the maximum potential difference (voltage) that the capacitor can safely handle without being damaged. Electrolytic capacitors have a few characteristics that make them different from other types of capacitors. They have a very high capacitance, which means they can store a lot of charge in a small size. They are also polarized, meaning that they have a positive and negative terminal and must be connected to a circuit in the correct orientation. Finally, they have a limited lifespan and may need to be replaced after a certain amount of time or number of charge/discharge cycles.

470K ohm 16mm Rotary Pot Variable Potentiometer Potentiometers are very useful in changing the electrical parameters of a system. It is a single turn 470K Potentiometer with a rotating knob. These potentiometers are also commonly called as a rotary potentiometer or just POT in short.  A potentiometer knob can also be used along with this POT for aesthetic purposes. This is a carbon track, single turn, adjustable resistances, of value 470KOhm Knob potentiometer. It is meant for mounting on panel and is supplied complete with a knob. The knob is affixed on the plastic spindle of the potentiometer and turns the spindle which changes the resistance. The variation of resistance is linearly proportion to the degree of rotation. Potentiometer, in electronic parlance, is a manually variable resistance. Because its most common consumer application is for controlling volume/tone of sound in broadcast receivers, it is loosely referred to as "volume" or ''tone''. It is not a meter with scale and needle. Potentiometers look different depending on size, power handled, application, value and type of material used. There is, however, a common feature-there is wiper which sweeps over a length of resistive material. The two ends of the resistive material as also the wiper are available to the user as electrical terminations. The user gets a variable resistance between the wiper and the two ends. Also check 16mm size 250K ohm rotary potentiometer (plastic shaft) sold by Iotcart. It has a tolerance of 20%. The potentiometer is designed for adjusting various parameters like voltage and current in electronic circuits.

4MHz Crystal Oscillator - (Pack of 10) The 4MHz crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz resonator, amplifying it, and feeding it back to the resonator. It provides clock pulses of 8 MHz frequency. The popularity of the crystals is due to the low cost. How are 4MHz crystal oscillators useful? One of the most important traits of the crystal oscillator is that it exhibits very low phase noise. In the crystal oscillator, the crystal mostly vibrates in one axis, therefore only one phase is dominant. This property of low phase noise makes them particularly useful in telecommunications where stable signals are needed, and in scientific equipment where very precise time references are needed. The result is that a quartz crystal behaves like a circuit composed of an inductor, capacitor and resistor, with a precise resonant frequency.
