Tantalum Capacitors

T491B225M020ZT capacitors are widely used in consumer electronics, automotive industry and industrial automation products. It is a type of capacitors that has its own unique properties. This particular type of capacitor is made from tantalum, which has an impressive dielectric strength and high thermal conductivity. It also has excellent fatigue resistance and offers better levels of performance than conventional ceramic or aluminum electrolytic capacitors.

Application Field

T491B225M020ZT capacitors are mostly used in consumer electronics and embedded systems. They are suitable for use in applications that require a low voltage value (<25 V) and relatively low capacitance values (<10 μF). These capacitors are significant in electrical engineering, specifically in power management applications. An example is their frequent usage in high-end TV sets, where they are used to control the power fluctuations. They are also used in the automotive industry, where they are mainly being used to reduce the noise levels of active suspensions, cabling and machine transmissions. In industrial automation systems these capacitors serve to condition electrical signals, providing high-frequency filtering, buffering, and signal conditioning.

Working principle

The working principle behind a tantalum capacitor is quite simple. It is based on the fact that any material\'s electrical properties change when a potential difference is applied. When a potential difference is applied across two materials they produce an electrostatic field, the strength of which depends on the capacitance of the capacitor. This electrostatic field set up between the electrodes of a tantalum capacitor stores electrical energy. The stored energy builds up when a current flows through the capacitor, which ultimately produces a charge.

This charge produces a voltage across the terminals of the capacitor. This voltage has a capacitance value, which can be determined by the formula C=Q/V. The capacitance value is inversely proportional to the voltage applied to the capacitor.

Since tantalum has the ability to sustain extra voltages, it is used in the production of having extremely high levels of capacitance. They also require very low levels of leakage, as compared to other types of capacitors. As a result, T491B225M020ZT capacitors are highly efficient and provide stability to the circuit in which they are used.
