Zener diode transfers current forward and backward, while traditional diodes are only capable of transferring current forward.

Many different electronic systems use Zener diodes to control their circui's voltage levels.

While there are several ways of doing this, Zener diodes provide efficient voltage regulation without damaging the diode itself.

How Zener Diodes Work
Zener diode acts like a regular diode as current moves in a forward direction in its circuit.

However, when a large enough voltage is applied to the diode in the reverse direction, it travels against the current from the output to the input.

Zener diodes can limit the amount of current that passes through them so that the voltage going backward limits the voltage going forward.

Zener diodes are very small and can be integrated into virtually any electronic device, especially small circuits that cannot accommodate other forms of voltage regulation technology.

Zener diodes are also relatively inexpensive and are compatible with most other systems, making them the preferred voltage regulation device.

Variable resistors used as potentiometers have all three terminals connected. This arrangement is normally used to vary voltage, for example to set the switching point of a circuit with a sensor, or control the volume (loudness) in an amplifier circuit. If the terminals at the ends of the track are connected across the power supply then the wiper terminal will provide a voltage which can be varied from zero up to the maximum of the supply.

Kingtronics are potentiometers manufacturer since 1990. Trimming potentiometers are Kingtronics' first products. RKT-3006 is one of the Trimming potentiometers,It is used where very precise adjustments must be made.RKT-3006 has 3 terminal styles:3006W, 3006P, 3006Y. The screw must be turned many times (10+) to move the slider from one end of the track to the other, giving very fine control.

Capacitors are devices which store electric charge. They are usually made from two parallel metal surfaces with some insulating dielectric layer between them. If one of the plates is charged, and the other is grounded,  opposite charges will accumulate on it  by influence, while the net charge stays zero. The capacitance is the magnitude of charge on one plate Q divided by the voltage V across the plates.

The unit of capacitance is the farad. 1 F = 1As/V

The capacitance of two parallel metal plate of area A and d distance apart (supposed that the lateral sizes of the plates are much bigger than the distance between them) is

where e is called the permittivity of the insulating material between the plates.

The permittivity of vacuum is e0 = 8.85 ×10-12 As/(Vm).

The capacitance can be increased by applying high permittivity material between the metal plates, like paper, plastic, oil, mica, or ceramic. Typical capacitance values range from about 1 picofarad (pF, 10-12 F) about 1000 microfarads (mF, 10-6 F)

The symbol for capacitor in circuit diagrams is:

The capacitors are rated according to the voltage that can be safely applied across their terminals - breakdown voltage.

The energy stored in a capacitor is

Electrolytic capacitors use aluminium or tantalum plates immersed in a semi-liquid chemical compound which forms a thin insulating oxide layer on one of the electrodes. These types of capacitors are said to be polarized and can be used only in such way that the terminal denoted by “+” is always at higher potential as the “–“ one. Because of the thin oxide layer, the capacitance of the electrolytic capacitor is usually high, 1-1000 mF.

Dipped tantalum capacitors also have high capacitance but small size at the same time. They are made of a sintered tantalum powder core. Because of the pores, it surface is very large. The core is oxidized. The core is dipped into manganese nitrate solution,  than put in a furnace where  the nitrate decomposes into manganese oxide which fills the pores and serves as the other electrode to the capacitor.

Pls check SGS and Cross reference on below links:

Cross reference:

Select a higher voltage rated part (30% to 70%) than the maximum line voltage. In the case of low impedance circuits, the tantalum capacitor is likely to be stressed by current surges. In circuits which undergo rapid charge/discharge, a protective resistor of 1.0 ohm per applied volt is recommended. If this is impossible, a voltage-derating factor of up to 70% is recommended. A combination of tantalum capacitors can be connected in series to increase working voltage of the equivalent capacitor. In many power supply topologies where the di/dt through the capacitor is limited, such as most implementations of buck (current mode), forward converter and flyback, the requirement for series resistance is decreased to 0.1 ohm per applied volt. This level of resistance is used as a basis for the series resistance variable in a 1%/1000 hours 60% confidence level reference. This is what steady state life tests are based on. Certain test circuits such as ICT are likely to subject the capacitor to large voltage and current transients, which will not be seen in normal use. This should be taken into account when considering the capacitors rated voltage.

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval.
