Tantalum-polymer capacitors, also referred to as Polymer-tantalum capacitors, are a type of electrolytic capacitor. They are characterized by their small size and high capacitance per volume. Tantalum-polymer capacitors use an organic conducting polymer as an electrolyte and a thin film of tantalum metal as the electrodes. These capacitors have a wide range of applications, ranging from consumer electronics to automotive, medical and military systems.

One example of a tantalum-polymer capacitor is the TCOB1A336M8R. The TCOB1A336M8R is a surface-mounted device (SMD) tantalum/polymer capacitor. It has a capacitance of 33uF and a maximum operating temperature of +85°C. It is suitable for use in automotive, military, medical and consumer applications. The device has a wide range of operating temperatures and can operate from -55°C to +125°C. It has a lifespan of 1000 cycles at +85°C and 100,000 cycles at +25°C. The device is also compliant with the Restriction of Hazardous Substances directive (RoHS).

The working principle of tantalum/polymer capacitors is based on the electrochemical double layer (EDL) phenomenon. This phenomenon occurs when two different electrodes are placed in a medium, such as an electrolyte solution or a solid electrolyte. When a potential difference exists between the two electrodes, an electric field is produced between them. This electric field causes a charge transfer between the two electrodes and this is the basis of the EDL phenomenon. The EDL phenomenon is the most important factor in determining the capacitance of the capacitor.

Tantalum-polymer capacitors are used in a wide range of applications including consumer electronics, automotive, medical and military systems. They are used for filtering, power conditioning and energy storage applications. In consumer electronics, they are used for decoupling, bypassing and filtering purposes. In automotive applications, they are used for power conditioning and energy storage applications. In medical and military applications, they are used for critical system components.

Tantalum-polymer capacitors offer several advantages over traditional tantalum capacitors. They have higher capacitance-voltage ratio and are ideal for low-voltage applications. They also offer excellent volumetric efficiency, enabling high capacitance values in a board-level packaging. In addition, they are suitable for high temperature applications, have low self-discharge, low equivalent series resistance (ESR) values, and are RoHS compliant.

The TCOB1A336M8R is an example of a tantalum-polymer capacitor suitable for a wide range of applications. It has a high capacitance value, a wide range of operating temperatures and an excellent volumetric efficiency. It is compliant with the RoHS directive and is suitable for use in automotive, military, medical and consumer applications.
