Tantalum-Polymer capacitors, or Ta-Polys for short, are a type of non-polarized capacitor, typically used for decoupling, energy storage, and timing applications. They are usually constructed from a ‘sandwiched’ structure of a tantalum containing powder, an insulating polymer and a porous layer of conductive electrodes. In terms of their structure and operation, Ta-Polys are similar to Tantalum electrolytic capacitors but offer superior performance in terms of voltage ratings and frequencies. The M551B127K100AA is a type of Ta-Poly capacitor typically used in consumer electronic devices such as smartphones, devices, and tablets.

The M551B127K100AA has a maximum capacitance rating of 100uF, with a voltage rating of 6.3V. The operating temperature of the capacitor ranges from -55℃ to +125℃. The M551B127K100AA has a film dielectric structure, which ensures that it retains its capacitance level over a wide range of operating temperatures. The capacitor is also designed to provide low ESR and is suitable for high frequency applications, up to 30MHz.

The primary application field for the M551B127K100AA is in power management and energy delivery circuits. Its small size and lightweight construction make it well suited for applications that require high power and high levels of impedance. Its tight tolerance range, small size, and low self-inductance also make it perfect for various decoupling and timing applications. Its high frequency capabilities allow it to be used as a part of noise suppression circuits, such as in switching power supplies, radios, and other electrical equipment.

The working principle of the M551B127K100AA is based around capacitance. The capacitor works by charging the tantalum powder electrodes with the applied DC voltage, which produces an electric field. This electric field allows the capacitor to temporarily store and then slowly discharge the electric energy, based on the operating temperature. This makes Ta-Poly capacitors ideal for applications where continuous pulses of energy are needed and when high frequency performance isn’t a priority.

The M551B127K100AA is an excellent example of a Ta-Poly capacitor, offering superior performance in a range of decoupling, energy storage, and timing applications. Thanks to its small size and voltage rating, this Ta-Poly capacitor provides high power and impedance levels, ideal for consumer electronics and switching power supplies. Its low ESR, wide operating temperature range, and high frequency capabilities make it well suited for various noise suppression and timing applications.
