Tantalum Capacitors

A tantalum capacitor is an electrolytic capacitor, a passive electronic component, consisting of two electrodes - an anode made of tantalum and a cathode made of the oxide of tantalum. This type of capacitor is characterized by its very small size and high capacitance values, compared to other capacitor types of the same volume.

The M39003/09-0217/HSD is a high-density tantalum capacitor incorporating a solid electrolyte and hermetic sealing. The M39003/09-0217/HSD offers superior performance advantages over other conventional high-density capacitors due to its ultra-small size and high-reliability hermetically sealed structure.

The high-density tantalum capacitors feature low equivalent series resistance (ESR) and are suitable for decoupling and filtering applications in switch mode power supplies (SMPS), DC/DC converters, and other voltage regulation circuits.

Application Field

Tantalum capacitors are ideal for applications where space savings and high capacitance density are essential. The M39003/09-0217/HSD capacitors are used in a range of applications from mobile and telecoms equipment to computers, telecoms infrastructure equipment, and industrial automation products.

The M39003/09-0217/HSD capacitors offer increased peak ratings, derating characteristics for higher ambient temperatures, and low-profile design advantages requiring less board space in the most demanding height restricted applications.

Working Principle

The M39003/09-0217/HSD capacitors feature a solid electrolyte instead of a liquid electrolyte, making them more reliable and offering higher capacitance in comparison to liquid electrolyte tantalum capacitors. The solid electrolyte prevents leakage, reduces equivalent series resistance (ESR) and increases capacitance.

The hermetic sealing provides the M39003/09-0217/HSD capacitors with a sealed and reliable package which offers superior performance for high-density applications. The hermetic sealing also eliminates the risk of leakage or of any environmental contamination, making the capacitors suitable for use in the most demanding industrial and automotive applications.
