M550B127M100AS

Tantalum - Polymer Capacitors (TPCs) are a relatively new category of capacitors which have gained attention in the electronics and telecommunications markets over the past few years. The main difference between TPCs and traditional tantalum capacitors is their construction and working principle. TPCs are constructed using a solid tantalum anode, as well as an electrolyte mixture of polymers and other elements such as barium titanate, zirconium oxide, or titanium oxide. With these materials, a higher capacitance can be achieved than with traditional tantalum capacitors.

The M550B127M100AS is a TPC and is used in many applications. Among the most popular are in digital and analog communication devices, personal digital assistants or PDAs, and laptop computers. For digital devices, the TPC technology offers high capacitance values, low dielectric losses, and improved capacitance under AC loads. The device is also used as input and output grounding capacitors, common mode input filters, temperature compensation networks, and EMI suppression. It also has applications in the telecommunications industry, such as in DECT and GSM mobile phones.

The M550B127M100AS is a robust component, with high currents and voltages and excellent EMI performance. It is a good choice for use in higher temperature and high vibration environments such as those found in automotive and industrial applications. The component also has good stability over wide temperature range and can be used in DC to AC switching applications.

The working principle of the component is based on the capacitance change of the solid tantalum anode during the application of a voltage. This change in capacitance is based on the change in temperature and the associated changes in the ionic charge of the polymer electrolyte mixture. The component is designed to operate at a voltage of up to 17 volts, so it usually works between 650-800 thermal cycles. This contributes to the component’s excellent reliability and durability.

When using the M550B127M100AS component, it is important to take into consideration the component’s current capacity, leakage current, polarization, and ESR. Its reverse voltage capability should be at least twice the normal operating voltage and the maximum operating temperature should not exceed 70oC. It is also important to remember that the component should not be connected directly to a DC supply and that the component is sensitive to temperature, so temperature changes need to be accounted for in order to maintain a consistent performance.

Overall, the M550B127M100AS TPC is a great component for many applications, especially those which require a robust component that can handle higher temperatures, higher voltages, and higher current levels than a traditional capacitor. Its superior EMI performance and high reliability make it suitable for many different applications. Furthermore, its good stability over a wide temperature range makes it well suited for use in many different environmental conditions.
