T55P475M6R3C0500 Capacitors

Tantalum - Polymer Capacitors are widely used in a variety of applications, ranging from consumer electronics to medical, military, and industrial electronics. The T55P475M6R3C0500 is a popular, reliable and low cost product available in a variety of capacitance values.

Capacitance and Design

The T55P475M6R3C0500 has a maximum capacitance of 475μF and a maximum operating voltage of 5.5V, with a temperature-coefficient range between -55 and 85°C. Its construction consists of a tantalum anode and a porous polymer cathode, which are insulated by a coating of polytetrafluoroethylene (PTFE). The cathode includes a foam-like structure that enhances dissipation through its heat-sink and current distribution capabilities, further improving the thermal stability of the capacitor.

Applications

The T55P475M6R3C0500 is primarily used for decoupling and energy storage applications, due to its high capacitance values and low Equivalent Series Resistance (ESR). It is used in professional audio equipment to reduce unwanted noise and attenuate unwanted high-frequency signals. Likewise, it is well suited for use in automotive and industrial applications, where it can provide clean power and reduce the potential for circuit failure via voltage spikes. Additionally, its reliability makes the T55P475M6R3C0500 ideal for medical and military equipment, where it can provide reliable and consistent power delivery.

Working Principle

The working principle of T55P475M6R3C0500 is similar to that of other basic capacitors. It consists of two metallic plates insulated by a non-conductive material. When a voltage is applied to the T55P475M6R3C0500, electrons accumulate on the plates and create an electric field between the plates. This electric field is the source of the electrical charge stored in the capacitor. When an AC current is applied to the T55P475M6R3C0500, the electric charge of the plates alternates between positive and negative. This creates a changing electric force between the plates, which in turn causes a corresponding current to flow through the device. This current is smoothed out by the capacitance of the device, resulting in a composite AC wave form with a smaller amplitude. The amount of charge that is stored in the T55P475M6R3C0500 is proportional to the voltage applied to it. Therefore, when Too much current is applied to the capacitor, the voltage begins to drop, as the capacitor cannot store an infinite amount of charge. This is known as Voltage Drop or Equivalent Series Resistance (ESR).

Conclusion

The T55P475M6R3C0500 is a reliable, low cost and high performance tantalum-polymer capacitor that is ideal for a variety of applications. Its robust construction and quality insulation make it well suited for use in high-end consumer electronics, industrial designs, automotive designs, medical and military equipment. Its high capacitance and low ESR make it ideal for use in decoupling and energy storage applications.
