47K ohm 16mm Rotatory Variable Potentiometer Potentiometers are very useful in changing the electrical parameters of a system. It is a single turn 47K 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 47KOhm 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 pack of 5, 16mm size, 22K ohm rotary potentiometers available on Iotcart. These potentiometers have a tolerance of 20% and a total rotational angle of 300° ± 5°. They are described as carbon track, single-turn, adjustable resistances with a plastic shaft.

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.

4mm Heat Shrink Tubing Black - 1  Meter Heat shrink tube (or, heat shrink tubing) is a tube that shrinks in diameter when heated. After being heated with a heat gun, it shrinks to 50% of its original diameter. Heat shrink sleeve with a completely thermoplastic covered interior surface. When heated, the sleeve's diameter shrinks by 2:1 and the interior resin melts. The sleeve and the resin harden as they cool. This combination ensures resistance to pullout and perfect waterproofing for your connections, preventing a sleeve from slipping. In the case of a connector mounted on a cable (coaxial, for example), this sleeving ensures reinforcement at the point where the cable is generally subject to stress when the radius of the curve is small. To protect the connection, the tubing is wrapped around it and heated with a lighter, matchstick, oven, hot air gun, or similar tool. A soldering iron (held close but not touching the tube) or the heat from a lighter are both convenient but ineffective methods for shrinking the tube. These processes cause the tubing to shrink to one-sixth of its original diameter (depending on the heat shrink, 2:1 is the most common), resulting in a tight fit over irregularly shaped joints. This provides good electrical insulation, dust, solvent, and other foreign material protection, and strain relief. Heat shrink tubing, like any other plastic, can melt, scorch, or catch fire if overheated. Applications: Wire protection Joining Wires Electrical Insulation Cables and Wire bonding
