Tantalum - Polymer Capacitors

Tantalum-polymer capacitors are multi-layered components used in various electronic systems and circuits. They have different physical characteristics and are shaped like small aluminium canisters, with a black surface and round shape. The key component is a solid polymer that contains a tantalum powder, and the major focus for these devices is to offer high capacitance and stability to meet the stringent requirements in modern electronic devices.The T541X227M016AH8510 capacitor is a type of surface mounted tantalum-polymer capacitor. It is manufactured from a series of flexible layers, which are bonded together and moulded into its distinctive canister shape. It has a capacitance of around 22µF and a voltage rating of 16V, and has a tolerance of ±10%.

Application Field

T541X227M016AH8510 capacitors are used in a variety of applications in the aerospace, automotive, consumer electronics and audio/video industries. The inherent durability of the device makes it ideal for harsh or changing environments such as in engine compartments, and it is suitable for use in a wide range of temperature and vibration conditions.They are widely used in motor control systems, to filter out noise and interference, increase battery life and provide circuit protection. In automotive applications, they are used as protection from short-circuits and over-voltage, as well as providing filtering of ac power to dc components and ICs for improved reliability. In consumer electronics, they are used for audio components, such as amplifiers, pre-amps and receivers, due to their low impedance and high capacitance.

Working Principle

When a tantalum-polymer capacitor is connected to a circuit, the positive terminal’s metal layer is polarized, creating a positive polarity, and the negative terminal’s metal layer is polarized in a negative direction. This creates an electrical potential across the two terminals, which is then used to store electrical charge.The polymer layer between the two metal layers acts as a dielectric medium, which generates an electrostatic field between the two metal layers when a potential is applied. This means that the capacitance of the device increases as the charge on the terminals increase.Tantalum-polymer capacitors are known for their high tolerance to large voltage swings and their ability to store charge for a longer period, even when the potential between the two terminals is kept constant. They also offer the advantage of being highly reliable and stable over a wide temperature range.
