Tantalum capacitors are components made with tantalum material, which holds a great advantage over other capacitors in terms of its higher load capacity, improved frequency responses, and better temperature stability. In comparison to other commonly used materials like aluminum and polymer, tantalum capacitors are way more robust and reliable. The M39003/09-0247 is an example of a series of high quality and highly reliable solid tantalum capacitors offered by Vishay, usually used in a variety of applications.

The M39003/09-0247 is a miniature, case-sized, hermetic, soldered, floating, and single anode tantalum capacitor with a capacitance range of 0.1µF to 4.7µF. It is the most preferable choice for applications that require improved frequency response, low operating temperature, and higher performance. It is mainly used in the automotive industry, avionics industry, and for military applications. The construction of M39003/09-0247 makes use of a tantalum slug as cathode, niobium alloy anode, and tantalum anode as dielectric.

The M39003/09-0247 has an operating temperature range of -55°C to 125°C. It also has a rated voltage range of 4V to 16V with low ESR and excellent heat dissipation. The capacitor is also closely monitored and tested in a rigorous environment to guarantee maximum performance. Apart from this, the M39003/09-0247 also has a very small and compact size, making it very attractive for many applications.

The working principle of M39003/09-0247 is based on two basic concepts of capacitors. One of them is dielectric absorption, which occurs when a material is placed in between the two conductors, and the other is called dielectric relaxation. Dielectric absorption is the mechanism by which the capacitance of the M39003/09-0247 increases when it is subjected to an alternating current. This is due to the fact that when an alternating current is passed through the capacitor, it causes the dielectric material between the two conductors to absorb more electric field and cause an increase in capacitance.

On the other hand, dielectric relaxation is the mechanism by which the capacitance of the M39003/09-0247 decreases when it is subjected to a static or DC current. This occurs when the material between the two conducting plates is not able to absorb any more electrical field and the capacitance starts to decrease when a DC current is passed through the capacitor.

The M39003/09-0247 is a highly reliable and efficient capacitor with excellent heat dissipation, low ESR, and a wide operating temperature range, which makes it suitable for a variety of automotive, avionics, and military applications. With its higher load capacity, improved frequency responsiveness, and better temperature stability, it is the perfect choice for high performance applications.
