Application Field

T540D226M030DT8605 is primarily used in a wide range of applications where the demands are high in terms of performance and reliability. It is widely used in automotive and industrial applications, such as motor control, power supply, robotics and audio. It is also used in power supply and telecommunication devices, such as cellular radios, radio receivers and Wi-Fi transmitters.

Working Principle

Tantalum-polymer capacitors use a combination of tantalum powder and polymers to form a thin film that is then rolled up and encased in a wound form. The thin film acts as a dielectric material between two conductive plates that make up the capacitor. When a voltage is applied to the capacitor, electric charges are stored onto the plates and a polarized electric field is created, allowing the capacitor to store energy.

The structure of a tantalum-polymer capacitor is a thin dielectric material that is sandwiched between two metal plates, forming the electrodes of a capacitor. The thin dielectric layer is made of a mixture of tantalum powder and a polymer (which acts as a binder). This dielectric layer provides electrical insulation between the two metal plates. When a potential is applied across the capacitor, charges move between the metal plates, creating an electrical field. This field is strong enough to store charge and create a polarized state in the capacitor. The polarized state is capable of storing electric energy, and this energy can be released in the form of electric current.

As compared to traditional aluminum or ceramic electrolytic capacitors, a tantalum-polymer capacitor offers advantages such as improved temperature and voltage stability, high capacitance, long service life and low equivalent series resistance (ESR). Moreover, it can operate at very high temperatures (up to 125°C) and features low self-discharge (<10 μA).
