Tantalum Capacitors

Tantalum capacitors are surface mount or through hole capacitors composed of tantalum metal and oxide. They provide highly stable capacitance over a wide range of temperatures in miniature size configurations, and are best characterized for their reliability and high volumetric efficiency. Typical applications of tantalum capacitors include filtering, decoupling, bypassing, energy storage, timing, and polarity protection for circuits, and also for electromagnetic interference (EMI) suppression.

M39003/01-5242/TR is a type of tantalum capacitors that is specifically designed for the Military specification market. It features a low ESR, stable capacitance over a wide temperature range, excellent high frequency performance, and high reliability. The M39003/01-5242/TR is available in basic capacitance and voltage ratings up to 47uF and 50V, respectively.

The M39003/01-5242/TR is specifically designed to meet the stringent requirements of the Military specification market, where circuits must withstand extreme temperatures and vibration, meet high reliability requirements, and provide a low ESR stability. Due to its high reliability and highly stable capacitance over a wide temperature range, the M39003/01-5242/TR is ideal for use in military applications where electrical performance and reliability of electronics are critical.

Working Principle of M39003/01-5242/TR

Tantalum capacitors are constructed with a conducting layer of tantalum oxide, two anodes formed out of sintered tantalum powder, and electrolyte (in solid tantalum capacitors) or a liquid electrolyte (for wet tantalum capacitors). The two anodes are usually separated by a dielectric layer, which is formed from the tantalum oxide. This dielectric layer provides the capacitance, as capacitance is directly proportional to the thickness of the dielectric layer.

In the case of the M39003/01-5242/TR, the capacitance is stable over a wide temperature range, as the thickness of the dielectric layer remains constant despite changes in temperature. This is due to the fact that the materials used in the construction of the capacitor are not subject to thermal expansion or contraction (as opposed to other materials such as ceramics, which do expand and contract with temperature change). Additionally, the extremely low ESR and high reliability of the M39003/01-5242/TR is due to the solid construction of the capacitor, as well as the use of high purity materials.

Conclusion

The M39003/01-5242/TR is an excellent choice when considering a tantalum capacitor solution for Military specification applications. It is highly reliable, offers a low ESR, excellent high frequency performance, and its capacitance remains stable over a wide temperature range. Additionally, the size availability of the M39003/01-5242/TR makes it a great choice for applications where space is a limiting factor.
