Tantalum Capacitors

The M39003/01-5550/TR type tantalum capacitor is a small sized, long life, solid electrolytic capacitor with reliable performance. It is made of tantalum metal and has a rectangular, aluminum-manganese oxide dielectric element. The anode material is a tantalum manganese oxide, and the cathode material is silver-plated tantalum. These capacitors are highly reliable, with a relatively low ESR and long life. It has good temperature stability, excellent voltage stability, and is available in a variety of sizes and packages.

The application field of M39003/01-5550/TR type tantalum capacitor includes filtering, decoupling, timing, snubbing, bias, de-spiking, etc. It requires some special skills to correctly pick and place the right tantalum capacitor in a circuit. It is used in a wide range of applications in various industries such as automotive, industrial, telecommunications, avionics, military and aerospace.

The working principle of M39003/01-5550/TR type tantalum capacitor is that it stores energy in a capacitor’s tiny electrical field by drawing tiny electric charges to conductive sheets on opposite sides of an insulating material outside of it. When DC voltage is applied to the capacitor a small electric field builds up (a stored charge) between the sheets. This electric field continues to build up until an equal but opposite electric field is created by a counter charge from an opposite side to the conductor.

Tantalum capacitors are constructed in such a way that the metal dielectric element is sealed in a tantalum holder, with both being filled hermetically with a special organic compound. This ensures a low equivalent series resistance (ESR) and helps reduce stress caused by voltage fluctuations, improving reliability and life span. This capacitance provides surge reliability even when operating under severe environmental conditions.

Tantalum capacitors have an extremely high capacitance to volume ratio, making them ideal for use in applications where space is limited. The capacitors are also very robust and capable of withstanding high temperatures, making them suitable for use in high-temperature environments. Their high-frequency performance is also very good.

Tantalum capacitors are one of the most reliable and cost-effective capacitors available. They can be used in a wide range of applications in various industries. When selecting the right capacitor for an application, one must consider the type of tantalum capacitor, size, package, and other factors. With the right selection, tantalum capacitors will provide reliable performance for a variety of applications.
