Tantalum - Polymer Capacitors

Tantalum-Polymer capacitors are capacitors that use the metal tantalum as the anode and a combination of plastic and crystalline materials for the cathode. They are often referred to as polymer electrolytic capacitors, due to their addition of an electrolyte, usually an organic dissolved solid, which in and of itself adds a layer of versatility making them more suitable for some applications and not so suitable for others. The TCJD106M050R0090 is a popularly used version of this type of capacitors and is used extensively in applications such as integrated circuit and other electronic categories, meaning they have multiple usage options.

Application Fields

Tantalum-Polymer capacitors such as the TCJD106M050R0090 are widely used in the fields of communications equipment, computer and other information technology, automotive electronics, industrial control, home electrical appliances, medical equipment, office automation, toys and other consumer electronics. They are also used in various audio and video devices, wireless communications, charging and discharging protection circuits, multi-functional copiers and power supplies.

In comparison to other conventional capacitors tantalum polymer capacitors are able to provide higher energy density, greater operating temperature range, better environmental stability and longer service life. The TCJD106M050R0090 is especially favored for its high capacitance, low equivalent series resistance (ESR) and consistent capacitor characteristics. These properties make the capacitor perfect for use in high-frequency EMI filters, tuned circuits and DC-DC converters.

Working Principle

Tantalum polymer capacitors use an electrolyte to form an electrical path between the positive and negative electrodes, thus allowing an electric current to flow. The electrolyte used in the TCJD106M050R0090 is Polypyrrole (PPY), a plastic containing nitrogen and oxygen atoms, which when applied to the electrodes forms a dielectric. The electrodes are formed by mixing a tantalum powder with a plastic casing, which is then heated to form a solid piece.

When the electric field is applied to the POLY Electrolyte, the molecules will orient themselves to form two polarized layers, a positive layer on the anode and a negative layer on the cathode. In this way a charge can accumulate on the electrodes and an energy is stored in the polarized molecules. This process is called “polarization” and the capacitance describes how much charge can be stored in the capacitor.

The advantage of the TCJD106M050R0090 is that the charge transfer rate can be very high compared to other capacitors, allowing the capacitor to store more charge at a given voltage range. This makes the tantalum polymer capacitor ideal for use in high frequency noise suppression and power filtering applications. It is also very reliable, with excellent temperature stability and long service life.

Conclusion

The TCJD106M050R0090 capacitor is a TAJ capacitors specifically designed with a polymer electrolyte and tantalum anode, making it much more suitable for an array of application fields. This type of capacitor is known for its extremely high charge transfer rate, temperature stability and long service life. With its low ESR, efficient operation, and high reliability, it makes a great choice for use in circuits of all types in the military, automotive, audio, and video industries.
