Tantalum capacitors are capacitors that use tantalum as the primary anode material. They are divided into two main categories: tantalum electrolytic capacitors and tantalum solid-state capacitors. Tantalum polymer capacitors constitute a sub-category of tantalum solid-state capacitors. TCJT476M006R0120 is a 25V, 0.0047uf tantalum polymer capacitor designed with KEMET Corporation’s polarization technology.

Application Field

The TCJT476M006R0120 is designed to be used in computer motherboards that require the highest level of electrical stability, such as the newer high-performance Microprocessor motherboards. Also, it can be used in wireless communication systems, digital cameras, cable modems, cell phones, etc. Furthermore, military applications and aerospace systems that require high reliability and long lifetime also consider its use.

Working Principle

When the capacitor is being charged, the anode is polarized such that the oxide layer between the electrolyte and the tantalum material is converted into a porous insulating layer. When it is discharged, the charge can be released from the anode through the oxide layer. The oxide layer acts as a dielectric material that has a relatively high capacitance. This is the basic working principle of the TCJT476M006R0120 capacitor.

In the TCJT476M006R0120, the tantalum material is coated with a layer of conformal epoxy coating. This coating improves reliability and allows the capacitor to endure all types of adverse conditions, such as extended temperature ranges and vibration. Furthermore, this coating gives the capacitor a semi-permeable electrode which makes it possible to control the voltage applied by the electrical current.

The TCJT476M006R0120 also features a lamination technology that ensures an even distribution of the charge over the capacitor surface. This allows for lower voltage drops across the capacitor, improving its overall electrical performance. Additionally, the capacitor uses conductive polymer and solid surface-mount electrolyte for improved performance and stability.

KEMET Corporation’s Polarization technology also allows the TCJT476M006R0120 to offer excellent temperature, humidity, mechanical and electrical stability. This means that the capacitor will maintain its electrical characteristics over an extended period of time. Also, it provides reliable operation in high temperature environments.

Conclusion

The TCJT476M006R0120 is a 25V, 0.0047uf tantalum polymer capacitor designed with KEMET Corporation’s polarization technology. Its application field consists of computer motherboards, wireless communication systems, military applications and aerospace systems that require high reliability and long lifetime. Moreover, its working principle consists of the anode being polarized thus creating an oxide layer that acts as a dielectric material and allows the charge to be released when the capacitor is discharged. This is complemented by the conformal epoxy coating, conductive polymer and solid surface-mount electrolyte that improve the capacitor’s performance and reliability.
