Tantalum – Polymer capacitors are also commonly found in automotive fuel injection systems, power steering control units, and Engine Control Units (ECUs). They are also found in LED lighting control modules, ignition systems and thermometer devices.

Working Principle

Tantalum – polymer capacitors are operated in a similar way to other capacitor types. They are used to store and temporarily store electrical charge between the two poles of the device. When a voltage potential is applied, electrons will flow across the two poles making the capacitor charge.

The capacitance of a tantalum – polymer capacitor is determined by the thickness and area of the electrodes in each section of the device. Generally speaking, thicker electrodes and higher surface area mean higher capacitance.

There are several important characteristics to consider when choosing a capacitor. These include its operating temperature range, rated voltage, leakage current, and ‘self-healing’ capability - which prevents failure by automatically resetting capacitors.

Advantages of Tantalum – Polymer Capacitors

Tantalum – Polymer capacitors provide many advantages over other capacitor types. They offer higher capacitance for a given volume, higher temperature ratings andu lower ESR, which increases the frequency and power handling capabilities of the device. Additionally, they are resistant to shock and vibration and have better moisture, chemical, and corrosion resistance.

The temperature stability of tantalum – polymer capacitors makes them suitable for automotive and industrial applications, where temperature and vibration may be factors. In addition, their size makes them ideal for portable applications, where space and weight are a concern.
