A Brief Note on Polymer Capacitors & Wholesalers of Panasonic Capacitors

A Brief Note on Polymer Capacitors & Wholesalers of Panasonic Capacitors Polymer capacitors are available in four different varieties. Each type has different electrode materials, application targets, packaging and electrolytic materials. Industrial applications that can effectively benefit from these components include speciality lighting, power inverters and motor drives. One of the distinguishing characteristics of these components is their extremely low Equivalent Series Resistance (ESR).

1. Layer polymer aluminium capacitors These components have an aluminium cathode and use conductive polymer as electrolyte. It covers a voltage range of 2-25 Volts. Moreover, it renders effective capacitance range between 2.2-560 ÂľF (microfarad), depending on the specific electronic model. Based on the applications, customers can purchase layer polymer aluminium capacitors manufactured by Panasonic from reliable Panasonic capacitor suppliers at competitive prices.

2. Wound polymer aluminium capacitors It is based on conductive polymers and aluminium. These components cover a wide range of capacitance values and voltages than other types of polymer capacitors. The wound style, just like the layered polymer

electrical components, has very low ESR. Some of the wound polymer capacitors have ESR values even below 5 mΩ (Megaohm). Although the wound style components are not as compact as the layered capacitor but they can still be surface mounted.

3. Polymer tantalum capacitors These have a tantalum cathode and employ a conductive polymer as electrolyte. Voltage of these capacitors ranges from 1.8-35 volt. Whereas, the capacitance range of these electrical components ranges from 2.7680 µF. 4. Polymer hybrid aluminium capacitors These electrical components use a combination of a conductive and liquid polymer in order to serve as the electrolyte and aluminium as the cathode. Made from latest technology and machinery, these capacitors offer high conductivity and very low ESR. They offer voltage range of 25 to 120 mΩ. In order to ensure high standards of quality, these electrical components can be purchased from reliablePanasonic capacitors wholesalers.

Advantages of using polymer capacitors

Four type of polymer component shares a wide range of desirable electrical properties, despite differences in their constructions and materials. Some of the advantages of using polymer capacitors are mentioned below.

1. Excellent frequency characteristics Due to their low ESR values, these polymer capacitors have low impedance near their resistance point.

Lower impedance effectively reduces Alternating Current (AC) ripple in different power circuits.

2. Stable capacitance These capacitors remain stable over the time as compared to ceramic capacitor. Stability is important in the use of these capacitors in industrial and automobile industries. In some cases, loss of 90% capacitance or more for ceramic capacitors compared to conventional capacitors was reported.

3. Enhance safety Polymer capacitors have a self-healing capacity. The repair work of capacitors takes place in response to the joule heating that occurs when a dielectric defect triggers a short circuit. Conventional capacitors can suffer from different safety issues when electrical stresses create defects in the oxide film that forms the dielectric of the conventional capacitors.

•Panasonic polymer capacitor distributors and suppliers Based on the industry applications, customers can avail different types of polymer capacitors from reliable Panasonic capacitors distributors. With the aid of their large storage capacity and rich vendors’ base, these distributors have been able to meet the bulk demands of polymer capacitors in the most efficient manner.

Conclusion With rapid increase in the use of capacitors in industrial applications, the need for more robust capacitor solutions was felt. Components manufactured by using polymer technology are best suited for different industrial applications. These are known for their rich attributes such as high capacitance, high voltage, high temperature & high ripple current. Longer life and low ESR make these polymer components highly demanded in various industrial and automobile applications.
