Tantalum Capacitors

Tantalum capacitors are one of the most widely used types of capacitors in today’s electronics industry. A capacitor is an electronic device that stores and releases a certain amount of energy. These capacitors vary in size, type, and application, and they are produced by many different manufacturers. T491E108K004AT is a particular type of tantalum capacitor that is becoming increasingly popular due to its cost effectiveness and reliability. This article will discuss the application field and working principle of the T491E108K004AT capacitors.

T491E108K004AT capacitors are generally used in a variety of industrial and commercial applications, such as computers, cell phones, automotive electronics, and consumer electronics. These capacitors are especially suited for circuits that require higher capacitance, low ESR, and high ripple current capability. Furthermore, these capacitors are perfect for demanding applications that require a wide temperature range and long stability. The T491E108K004AT capacitors are also used in high-precision circuits due to their extremely high efficiency.

The working principle of these capacitors is quite simple. When an electrical signal passes through the capacitor, the device restricts the flow of current by storing electrical energy. This stored energy is known as the capacitance and is represented in Farads (F). When the current passes through the capacitor, the device dissipates energy, known as the equivalent series resistance or ESR of the capacitor. The ESR is measured in milliohms (mΩ). Beyond the ESR, the capacitors also feature an extended temperature range of -55°C to +125°C.

As far as construction of the T491E108K004AT capacitors is concerned, they consist of five parts: an anode, a cathode, an electrolyte, a dielectric layer, and a termination. The anode and cathode are typically made of tantalum powder, while the electrolyte is usually composed of a mixture of aqueous ammonium chloride and sulfuric acid. The dielectric layer is composed of an oxide layer which is usually an oxide of tantalum. Finally, the termination is typically composed of gold, silver, tin, or lead.

T491E108K004AT capacitors are highly regarded due to the many features they possess. In addition to their superior performance characteristics and wide temperature range, these capacitors are highly reliable and cost-effective. This makes them perfect for a range of industrial and commercial applications, as well as high-precision circuits. As a result, the T491E108K004AT capacitors are expected to see increasing usage in the near future.
