Tantalum - Polymer Capacitors

Tantalum - Polymer Capacitors are widely used in electronics due to their high energy density and low ESR (equivalent series resistance). The T540D476M020AT8505 is a popular Tantalum - Polymer Capacitor with an operating temperature range of -55°C to +105°C. It has a voltage rating of 10V, a capacitance of 476µF, and is rated to dissipate a maximum of 0.8W of power.

Application Fields

Tantalum - Polymer Capacitors are used in a wide range of applications. These include power backup in routers, mobile base stations, and broadcast transmitters, as well as for suppressing high-frequency signals in audio power amplifiers and for increasing efficiencies in point-ofload (POL) regulators. They can also be used to hold charge in safety systems such as fire alarms.

Working Principle

The T540D476M020AT8505 works according to the principles of electrostatics. When a voltage is applied to the terminals of the capacitor, the metal plate inside the capacitor collects the charge, and the dielectric material between the plates stores the charge. When the voltage is removed, the charge stored on the metal plates is released, allowing current to flow.Since the metal plates in Tantalum - Polymer Capacitors are held in place by the dielectric material, they are able to carry a much higher charge than traditional electrolytic capacitors. This allows them to store more charge in a much smaller space, giving them their high energy density.Tantalum - Polymer Capacitors also have a much lower ESR than electrolytic capacitors, meaning they are able to release their stored charge more quickly, which is beneficial in applications that require a rapid charge/discharge cycle.

Conclusion

The T540D476M020AT8505 is a popular Tantalum - Polymer Capacitor that is able to store a high charge in a small space, and is able to deliver current quickly. It is widely used in a variety of applications, from power back ups to audio amplifiers and safety systems. As well as being small in size, the capacitor is also robust and long lasting, making it a reliable and cost-effective choice for many modern electronics applications.
