Tantalum capacitors, sometimes referred to as Ta capacitors, can be found in a variety of electronic devices ranging from communication and video equipment to computers, automotive electronics and even medical equipment. Tantalum capacitors offer a number of advantages over other types of capacitors including higher capacitance, higher temperature operating range, smaller size and lower ESR (Equivalent Series Resistance). This makes them ideal for applications where small size, low ESR, or high current capacity and temperature range is of the utmost importance.

Tantalum capacitors are used in a variety of applications in a wide range of industries and products. For instance, they have been used to create dynamic RAM circuits and flat panel displays. They are used in noise filters to help reduce interference. They can also be employed for frequency tuning and for bypass applications. Additionally, these devices are very popular in mission critical applications and are used in high frequency oscillators, automotive circuits, and circuits that require low ESR.

T350B225M025AT capacitors are designed to provide the maximum capacitance, temperature capability, and reliability in a small package. They offer a wide temperature range of -55°C to +125°C and are available with a variety of case styles and termination options. These capacitors are ideal for applications such as automotive and computer system circuits, AC/DC converters, measuring equipment, lighting systems, telecommunications, and ultra low ESR batteries.

T350B225M025AT Working Principle

Tantalum capacitors are polarized electrolytic devices with the ability to store electrical energy. The internal structure of a tantalum capacitor consists of an anode composed of sintered tantalum powder, and a liquid electrolyte where the dielectric material that connects two plates is permeable. This structure enables tantalum capacitors to be much smaller than their aluminum electrolytic counterparts. It also enables them to be used more frequently in applications requiring both low and high voltage.

Tantalum capacitors work on the same basic principle as all other variants of capacitors – by storing and releasing electrical energy through the release of electrons. The voltage is applied across the device, causing an electric current to flow. This electric current deposits a thin layer of metal on the anode. This thin layer of metal is known as the dielectric material and is the component responsible for the device’s capacitance. When the voltage source is removed from the circuit, the electrons stored within the dielectric material begin to return to the cathode, releasing the energy stored in the dielectric material.

Tantalum capacitors are used in a variety of electronic products and systems. For instance, they are commonly used in power supplies, memory back-up circuits, automotive electronics, audio-video equipment, and many other applications. In any application, they offer superior temperature stability, increased current capacity, and low ESR. As such, they are an excellent choice for both high-power and high-reliability applications.
