Introduction to Tantalum Capacitors

Tantalum capacitors are one of the most important devices in the electronics industry today. They are typically made with a solid electrolyte, usually tantalum pentoxide along with manganese dioxide, that forms an anode. The anode is then electroplated with a thin layer of tin-lead alloy. The most common type of tantalum capacitor is the dry-mode capacitors which have an electrolyte of tantalum powder filled in an airtight casing. These are widely used in the automotive, entertainment, medical, and telecommunications industries.

Benefits of Tantalum Capacitors

Tantalum capacitors have some inherent advantages over other types of capacitors, including their high power density, their low ESR value (equivalent series resistance), and their excellent temperature stability. They are also highly stable under shock and vibration loads and are very reliable. Other benefits of tantalum capacitors include their small size, making them ideal for thin profile equipment, and their high capacitance which can be achieved with small case sizes. In addition, they have a very low self-discharge rate, making them ideal for applications where low discharge rates are desired.

TM3C476K016HBA Application Field and Working Principle.

The TM3C476K016HBA is an integrated chip-based tantalum capacitor, available from Voxsemi, which provides a high performance, low impedance solution for power supply decoupling and other high frequency applications. This device offers excellent frequency capability, with a high crossover frequency of over 28 MHz, and a high frequency self-test for tracking open inductors and capacitors.The unique design of this integrated device makes the TM3C476K016HBA ideal for circuit designs which require a low ESR capacitor. The ceramic core provides a high rate of charge accumulation, which is easily dischargeable even at low frequencies. The on-chip capacitor is constructed from a layer of Pt-Sn alloy and powder-coated tantalum dielectric material. The anode and cathode metallization are patterned specifically to ensure low ESR and low impedance operation.The principle of operation for this device is simple and reliable. The on-board capacitor acts as an antenna, harvesting energy from the surrounding field and storing it within the device. The stored energy is then routed to the load through a hybrid circuit including resistances, and current and voltage controlled transistors to deliver an accurate voltage to the load. With its low ESR, TM3C476K016HBA exhibits excellent charging and discharging characteristics.

Conclusion

Tantalum capacitors, such as the TM3C476K016HBA from Voxsemi, are essential in the electronics industry. They offer higher power density, smaller profiles, and a low ESC rating, making them ideal for a variety of applications. Furthermore, the on-board storage of energy and the ability to accurately regulate discharge to the load makes them an efficient choice for power supply decoupling and other high frequency applications.
