Tantalum-polymer capacitors are a type of surface mount capacitor that combines the properties of a polymer electrolyte and a metal-oxide layer to form a compact, lightweight package. TCJX477M006R0055 is a popular choice amongst this family of capacitors, used in many applications. In this article we will explore the application field and working principle of TCJX477M006R0055.

TCJX477M006R0055’s primary area of application is for high-speed transceiver and switch applications, particularly in areas where size, weight, and power (SWaP) optimization is desired. Due to its small case size, low ESR, and high capacitance per unit volume, it greatly increases efficiency and improves operating temperatures. It is commonly used in aerospace and automotive applications, communication systems, digital cameras, consumer electronics, and a variety of military systems.

Acting as an energy storage device, the working principle of a tantalum-polymer capacitor is based on the use of a porous tantalum anode covered with a dielectric layer comprised of a solid electrolyte-solid polymer material. Electrodes are deposited onto either side of the porous anode using a vacuum deposition process. The presence of the electrolyte gives the device its capacitance and its ability to store energy. Asa current is passed through the capacitor, the dielectric layer is polarized, resulting in the formation of a space charge between the anode and cathode. The anode is negatively charged, while the cathode is positively charged. This creates a charge-separation and potential difference (electric field) between the two electrodes, causing an electrical energy to be stored within the dielectric layer.

TCJX477M006R0055 has a capacitance rating of 47μF with a maximum operating temperature of 85°C and a minimum operating temperature of -55°C. The maximum ESR (equivalent series resistance), a measure of how well a capacitor resists fluctuations, is 28mΩ. The capacitor has good high-temperature operation and low-ESR, making it ideal for high-quality and high-speed signal transceivers.

TCJX477M006R0055 is also capable of withstanding high voltage surges, up to 16V DC in normal operation. This makes it highly suitable for applications that require reliable overvoltage protection, such as power supplies or communication systems. It also has a long service life of up to 10,000 hours of continuous operation, with a self-healing feature that restores performance after a surge.

To summarize, TCJX477M006R0055 is an ideal choice amongst tantalum-polymer capacitors. It is widely used in aerospace and automotive applications, communication systems, digital cameras, consumer electronics and military systems due to its small case size, low ESR and high capacitance per unit volume. It also has a wide voltage range, good high-temperature operation, and low-ESR capabilities, as well as excellent overvoltage protection and a long service life.
