Get The Best Quality Capacitors At The Best Price From Panasonic Capacitors

Capacitors are used to store charge, or energy in simpler terms, and release it when required. It stores less amount of energy than a battery, but can provide current for a short amount of time by releasing energy or discharging, and can repeat the charging and discharging cycles. Capacitance of a capacitor can be increased by making permittivity of the dielectric bigger, increasing the surface of electrode, and making the insulator thinner. Though an ideal capacitor will only have a capacitance component but the actual capacitor has both a resistance component and inductance component.   

Panasonic is the leading manufacturer of capacitors of various types of use in a wide range of applications. Some of the capacitors that you can get from Express Technology Group, one of the leading Panasonic capacitors distributors, are:  

Variable capacitors: The capacitor changes its capacity by changing the area of the counter electrode. Tunable Panasonic capacitors need frequent changing, while trimmer capacitors need adjustment only once when assembling the circuit.   

Polarized capacitor: It has one of the two terminals only set to the plus side. It must be used in a DC voltage only on the plus side. Polarized capacitor available from Panasonic capacitors suppliers is more widely used as it has a small size and supports a large capacitance. Titanium electrolyte capacitors, aluminum electrolyte capacitors, and electric double-layer capacitors are examples of polarized capacitors.   

Non-polarized capacitor: The polarity of the voltage applied to the capacitor terminals is not regulated, so any of its terminals can be positive. It is possible to apply a voltage that goes up and down from zero potential, so the capacitor can be used directly in an AC circuit. Examples include film capacitors, ceramic capacitors, paper capacitors, mica capacitors, and air capacitors.   

Ceramic capacitors  

These capacitors use ceramic with a high dielectric constant. The use range of this capacitor available at leading Panasonic capacitors suppliers, such as Express Technology Group, has expanded greatly with the manufacturing of multilayer ceramic capacitors that have small size and large capacitance.   

Film capacitors  

These components use plastic film for dielectric, and have excellent high-frequency characteristics, and long life. Compared to ceramic capacitors, film capacitors available at Panasonic capacitors suppliers have a low heat resistance. However, they have excellent temperature characteristics, and possible high precision of capacitance. The capacitors also have higher performance compared to ceramic ones.   

Aluminum electrolyte capacitors  

These contain an aluminum oxide film, which becomes a dieelectric, which is formed on the surface of aluminum foil of the anode. An electrolyte liquid, consisting of a solvent in which electrolyte is dissolved, is used as an electrolyte or cathode. The capacitor has equivalent series resistance (ESR) higher than that of ceramic and film capacitors.   

Electric double layer capacitors  

It has an intermediate capacitance between an aluminum electrolytic capacitor and a secondary battery. The capacitor available with Express Technology Group Panasonic capacitors supplier has a capacitance density of nearly about a thousand times or more of an aluminum electrolytic capacitor.
