Introduction

Tantalum capacitors are increasingly gaining popularity in modern day electronic appliances, be it a radio, television or other communication equipment. The CWR26HC107MCHA\PR, a surface-mount tantalum capacitor, is used in a variety of industries and applications. It is one of the most common and popular types of capacitors available today. This article aims to discuss the application field and working principle of the CWR26HC107MCHA\PR.

Application Field

The CWR26HC107MCHA\PR is ideal for applications that require small form factor, reliable performance and lower ESR values. It is used in automotive, consumer electronics, medical, automotive and industrial electronics. The capacitor can be used to suppress noise in power lines, decoupling, high voltage suppression, filtering, energy storage, clock signal generation, signal continuity and filtering circuits, and RFIDs.The capacitor can also be used in DC-to-DC converters, LED driving applications, charger integrated circuits (ICs), switched-mode power supplies (SMPS) and power line filters. It can also be used in various lightning protection and current-limiting applications.

Working Principle

Tantalum capacitors operate on the principle of dielectric absorption. This means that the two conductive plates of the capacitor are separated by a third spacer, typically made of a tantalum pentoxide. When a voltage is applied across these plates, a current flows between them, which creates an electric field in the spacer. This electric field induces a charge into the spacer material, causing an increase in capacitance. This effect is known as dielectric absorption.The capacitor’s capacitance is determined by its physical size, the spacing between the two plates, and the dielectric material that separates them. The dielectric material used in the CWR26HC107MCHA\PR is tantalum pentoxide, which has a higher dielectric absorption than other dielectric materials. This results in a higher capacitance for a given size and spacing compared to other capacitors.

Conclusion

The CWR26HC107MCHA\PR is a powerful and reliable surface-mount tantalum capacitor with excellent performance properties. Its smaller form factor and high-quality construction make it an ideal option for a variety of applications, including energy storage, RFID, current-limiting, DC-to-DC conversion, and more. The capacitor operates on the principle of dielectric absorption, allowing for higher capacitance than other capacitor designs.
