Tantalum Capacitors

Tantalum capacitors are a type of capacitors that uses tantalum as the anode in its construction. The majority of tantalum capacitors have an electrolytic construction that makes use of manganese dioxide as the electrolyte. They are typically used in circuit design and construction for decoupling, and offers a range of features such as small size, high-temperature operation, and low-cost.

199D335X0025B1V1E3 Application Field and Working Principle

The 199D335X0025B1V1E3 is a type of tantalum capacitor and it has a 5 millimeter x 7 millimeter package, a 35V DC voltage rating and a nominal capacitance of 25µF. The capacitance tolerance is ±20%. It offers high stability and low ESR performance and is ideal for use in low-profile and portable equipment.

The design of the 199D335X0025B1V1E3 consists of a tantalum anode, an oxidized manganese dioxide cathode, and a ceramic dielectric. The ceramic dielectric provides a low dielectric constant which leads to a low capacitance. The oxidized manganese dioxide acts as an electrolyte, providing a current path between the anode and the cathode. This electrolyte helps to increase the capacitance rating of the capacitor by acting as a reservoir for charge.

The key applications of the 199D335X0025B1V1E3 are in medical, automotive, and communications equipment. In medical devices, they are used to help filter out noise in analog and digital signals, while in automotive and communications equipment they help smooth out power fluctuation, reduce electrical noise and improve overall performance. They are also ideal for noise filtering in audio/video systems, digital and power amplifiers, and in cellular phones.

They can operate in temperatures up to 125°C, which makes them suitable applications in power supply design. Thanks to the small size, these capacitors can be used in very confined places. Additionally, their high capacitance is important for designing filters for power supplies, allowing for an increased resonance on the ripple frequencies.

Thanks to their unique qualities, tantalum capacitors are used in many applications where small size, high temperature performance and stability are needed. They are also being used increasingly in military and aerospace applications in which miniaturization and component reliability are essential.
