Tantalum capacitors are electrolytic capacitors that use tantalum as their anode material in the electrolyte. The major benefit of the tantalum capacitor is its low equivalent series resistance (ESR), which allows for higher working frequencies. As a result, they are often used in high frequency and pulse applications, such as in power supplies. The M551B127M100AS is a very efficient and cost effective tantalum-polymer capacitor. It is a surface mount capacitance device which packs a great range of features in a small, efficient form factor.

Application Field

The M551B127M100AS is a capacitor ideal for high frequency, high efficiency and low power applications. It is often found in power circuits, audio amplifiers, signal processing systems, and radio frequency radio circuits. It is often used as a bypass in withstanding voltage and temperature variations. Additionally, it can be used in high-power applications, as it has a rated case temperature of +125°C.

Working Principle

Tantalum-polymer capacitors offer increased capacitance and improved performance compared to traditional tantalum capacitors due to the use of the polymer dielectric. The polymer dielectric reduces leakage current, increases capacitance and improves ESR, making it very suitable for high frequency applications. It can also be operated at higher voltages than a traditional tantalum capacitor. The M551B127M100AS is a surface mounted capacitance device with a capacitance of 100 µF, rated voltage of 10V and temperature range of -55°C to +125°C.

When the capacitor is connected to a power source, a voltage is applied across it and current flows through the device. The voltage across the capacitor will be equal to the applied voltage. The capacitor functions as a dielectric material, storing the electrical energy and blocking the direct flow of current. This energy is absorbed by the electric field generated within the capacitor and can then be used later. There are two characteristics that are important to consider when using a capacitors in a circuit, capacitance and ESR. The capacitance of the M551B127M100AS capacitor is 100 µF and the ESR is approximately 0.05Ω.

The M551B127M100AS offers many advantages compared to traditional tantalum capacitors, such as excellent high and low-frequency response, high capacitance density, and reliable operation over a wide temperature range. Due to its features, the capacitor can be used in many applications and is an ideal choice for high-frequency and high efficiency circuits.
