Tantalum capacitors are widely used in many applications due to their low size and weight, high capability, and low cost. However, they have relatively high ESR (equivalent series resistance) due to their construction. For this reason, high dynamic with low ESR are preferred. The M551B108M060AH is a capacitor particularly designed for high dynamic applications and is based on a patented electrode construction material (Tantalum-Polymer Electrode) that has a considerably lower ESR than other capacitors with similar capacitance.The M551B108M060AH capacitor is a small surface mount device that measures only 8.6 x 4.6 mm, with a maximum height of 1.35 mm. It has a rated voltage of 6.3 volts and a capacitance of 108 µF although other versions from 1 µF to 470 µF are also available. This low ESR capacitor offers better ripple current values and higher frequency response for higher frequency applications. As for IEC ESR levels, this type of capacitor offers lower levels than other types of capacitors available, making it an ideal choice for power applications.

The M551B108M060AH capacitor is based on a patented electrode construction material called Tantalum-Polymer Electrode. This type of construction consists of an anode made of tantalum powder integrated into a very thin form of polymer film. This process increases the amount of surface area between the anode and the electrolyte, resulting in a much lower ESR than other basic types of Tantalum electrolytic capacitors. The process also increases the reliability of the capacitor due to the conformal layer of polymer film between the anode particles and the electrolyte, eliminating the possibility of corrosion or leakage. On a downside, this tantalum-polymer electrodes may also increase susceptibility to electrical overstress (EOS).

The application field of the M551B108M060AH is driven by its key advantages such as ESR and ripple current values. These advantages are desirable for a wide range of applications including power conditioning, step-down converter circuits, voltage regulation, computer boards, switching power supplies and motor control circuits, audio circuits, DC-DC converters, and noise-filter circuits. This capacitor can also be used in other systems demanding better low-ESR performance such as automotive, medical, and instrumentation systems. In most cases, this capacitor is ideal for applications that require high frequency response with low ESR values.

The working principle of the M551B108M060AH is based on the basic rules that apply to electrolytic capacitors. As it accumulates a charge, the higher voltage causes an electrolyte to decompose and discharge its ions, transferring charge to the electrolyte. The charge-store material is the anode. Inside the anode, electrons are stored and eventually released as the capacitor charges and discharges. Since this type of capacitor is based on a highly innovative, patented technology that uses a novel construction material and unique electrode designs, its electrical performance is significantly better than other types of electrolytic capacitors. As such, it can meet high frequency requirements as well as deliver improved ripple current figures.

To sum it up, the M551B108M060AH tantalum-polymer capacitor is a device designed for high dynamic applications that require both low ESR and high frequency response. It is a small, surface mount device that is 8.6 x 4.6 mm and has a maximum height of 1.35 mm. It offers a rated voltage of 6.3 volts and a capacitance of 108 µF, and can be used in a variety of power applications such as power conditioning, voltage regulation, computer boards, switching power supplies and motor control circuits, as well as DC-DC converters and audio systems. Its working principle is based on the basic principles that apply to all electrolytic capacitors. It is important to note that this type of capacitor is very sensitive to EOS, so users should take proper precautions to avoid damaging the device.
