Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor characterized by a high capacitance per volume. They are used in a range of electronic components, typically where low-end capacitors with moderate capacitance values are required. Tantalum capacitors are widely used in communications, computing, industrial control, and automotive markets, and are available in a wide variety of configurations and sizes.

The M39003/01-5359H is a solid tantalum capacitor that is suitable for high frequency (30 MHz) and low voltage (35 V) electronic equipment. This small footprint capacitor features a low ESR, good reverse leakage protection, and high ripple current and durability. It can be used for general purpose DC blocking, bypass, and decoupling applications. Its small size makes it ideal for use in communication concepts, digital appliances, power switching systems, and high-end audio products where space is at a premium.

The working principle of a tantalum capacitor is based upon the electrochemical properties of tantalum. When two electrodes are immersed in a solution containing a dissolved electrolyte, electrical current can be drawn through the electrolyte and an electrochemical reaction will occur at the electrodes, forming a capacitor. The cathode, which is connected to the negative terminal of the capacitor, will precipitate the electrolyte on its surface, creating an insulating barrier. The anode, which is connected to the positive terminal of the capacitor, will absorb electrons from the electrolyte until a charge is built, forming a capacitor.

The M39003/01-5359H has a low ESR values (ESR stands for Equivalent Series Resistance) that is due to several factors, including the capacitor\'s polarity, its thickness, and the amount of tantalum present in the dielectric film. The film\'s thickness is usually determined by the amount of electrical volumetric charge that the capacitor can store; however, in this particular capacitor, the film is decreased in thickness in order to reduce the ESR. The low ESR values help to increase the capacitor\'s ripple currents and reduce its frequency response. This is beneficial when applications require low-loss power delivery or frequent frequency changes.

The M39003/01-5359H also has increased durability compared to conventional tantalum capacitors due to its increased sand layer thickness. This increased sand layer thickness is a result of the patented 3D production process, which involves filling the active anode layer with a heavily compacted sand-in-oil emulsion layer. This layer is then sealed to reduce the amount of leakage current. This increased sand layer thickness improves the overall durability of the device, which can result in a longer operating life and a higher reliability.

The M39003/01-5359H is an ideal device for a variety of applications. Its small size and low ESR values make it suitable for use in communication concepts, digital appliances, power switching systems, and high-end audio products where space is at a premium. Furthermore, its increased durability and reduced leakage current make it ideal for applications where frequent frequency changes and low-loss power delivery are required.
