Tantalum - Polymer Capacitors: T540D226K020DH8705 Application Field and Working PrincipleTantalum-polymer capacitors, also known as solid tantalum electrolytic capacitors or tantalum-polymer SMD capacitors, are solid-state, surface-mountable electrolytic capacitors with maximum capacitance within the range of 10 µF to 1000 µF with a maximum nomimal voltage of 40 V to 500 V. They have a wide range of uses in consumer and automotive electronics apparatus, and other specialized applications.

The capacitor consists of three main parts, an anode formed from the anodic oxide layer of tantalum, a porous cathode layer, and an electrolyte. The anode is made of tantalum which forms an anodic oxide layer through electrolysis. After formation, the dielectric formed is permanent due to a passivation layer which is separated from the electrolyte by the porous cathode layer. The capacitance is determined by the size of the anodic oxide layer and the proximity of the electrolyte to the anodic layer. The T540D226K020DH8705 capacitor is a type of tantalum-polymer capacitor with a maximum voltage of 170V, capacitance of 0.22 µF, and has a rated charge of approximately 30mA.

The working principle of the T540D226K020DH8705 capacitor is that of an electrolytic capacitor, where the anode and cathode of the device is separated from each other. When a voltage is applied across the anode and cathode of the capacitor, an electric field of polarizing force is generated due to the presence of the electrolyte separating the two electrodes. This field causes the anodic oxide layer to be polarized, which causes its electrical resistance to decrease, allowing current to flow between the two electrodes. When the capacitor is in a discharged state, the anodic oxide layer has very high resistance and the current flow between the anode and cathode is minimal. When a voltage is applied to the capacitor, the anodic oxide layer is polarized, reducing its resistance and allowing current to flow between the two electrodes. This flow of current between the two electrodes results in an electric charge stored in the capacitor, which can be used as a source of electrical energy when needed.

The T540D226K020DH8705 capacitor is mainly employed in consumer electrical products such as laptops, cellular phones, and tablets. Its small size and low cost makes it particularly suitable for thin CLIENT computing. These capacitors are also used in applications such as pulse-width modulation power supplies and audio power amplifier circuit applications, and are widely used in automotive electronics applications such as lights, infotainment systems, motor controllers, and full power systems. It is also used in military, telecommunication, and medical applications. Furthermore, tantalum-polymer capacitors used in general electronics are also becoming increasingly popular for use in robots and space technology.

In conclusion, the T540D226K020DH8705 capacitor is a type of tantalum-polymer capacitor with an anodic oxide layer, an electrolyte, and a porous cathode layer, which can be used in a wide range of applications. The working principle of the capacitor is that of an electrolytic capacitor, where the anode and cathode of the device is separated from each other by an electrolyte and the current flow between the two electrodes results in a charge stored in the capacitor. The capacitance of the T540D226K020DH8705 capacitor is determined by the size of the anodic oxide layer and the proximity of the electrolyte to the anodic layer, which enables it to be used in various consumer electronic, automotive, military and medical applications.
