Tantalum Capacitors: M39003/01-6234/98 Application Field and Working Principle Tantalum capacitors are electronic components which use tantalum bearings as its dielectric material. These components are widely-used due to their superior electrical properties, such as low loss and high-capacitance density, as compared with other dielectric varieties. The most popular types of capacitors used in this application are the M39003/01-6234/98 series. In this article, we will discuss its application and working principle. The M39003/01-6234/98 series is made up of a tantalum bearing differing in their sizes and shapes. These bearings are formed to create two distinct elements—the anode and the cathode—which are connected either by a porous layer of donated tantalum material or by a bridge that creates an asymmetrical spacing between the two elements. Due to their relatively small sizes, the M39003/01-6234/98 capacitors are commonly used in applications where the need for small, lightweight components is paramount. Moreover, their low leakage current makes them suitable for use in systems that require high stability. The main application of the M39003/01-6234/98 series sits in power supply systems. These capacitors can handle high-voltage pulsed power and reduce large charging currents. They are also suited for reduces spikes in power supply rails, high voltage bias, radio frequency biasing, and damping of high-frequency noises. Additionally, they can be used in signal filtering, especially for removing signal artifacts. The working principle behind M39003/01-6234/98 series can be explained using the concept of capacitance. When an electrical current is introduced, electrical charge begins to build up in the anode and the cathode of the capacitor. This buildup of electric charge forms an energy-storing effect known as capacitance—hence the name “capacitor”—which can be used to store energy and process signals. In the case of the M39003/01-6234/98 series, the charge builds up due to the presence of the porous layer of donated tantalum material between the anode and the cathode. The variation of charge buildup on either side of the capacitor coupled with the dielectric property of the tantalum leads to an increase in electrical capacitance. The capacitance of this type of capacitors has been measured at around 11.2 μF per 10mm, far surpassing the capacitance of other types of capacitors. Beyond electrical capacitors, the M39003/01-6234/98 series also offers a variety of other features. For instance, they can control the speed of signals, improve power supply noise immunity, protect circuits against over-voltage and provide an emergency operating window. Additionally, they can also be used in high-temperature applications in conjunction with ceramic capacitors for enhanced reliability and better performance. To sum up, the M39003/01-6234/98 series of tantalum capacitors is an extremely useful type of capacitors that offers many advantages which are indispensable for power supply applications. Thanks to its superior electrical properties, small size and low leakage current, it is well-suited for a myriad of applications from signal filtering to protection against over-voltage. In addition, its electronic capacitance, as well as the presence of other features such as variable speed control and noise immunity, makes it a highly sought after capacitor for modern application.
