Applications Fields for M550B108K050TG

The M550B108K050TG is suitable for a wide variety of applications. It can be used as an input decoupling capacitor for RF front-end modules in mobile phones, a bypass capacitor in oscillator circuits, a voltage-regulator module (VRM) capacitor for notebook PCs and digital cameras, and a signal-coupling capacitor for automotive multimedia equipment. The capacitor can also be used as a signal-coupling capacitor for Bluetooth, Wi-Fi, baseband, and Zigbee applications.

Working Principle

Tantalum Polymer Capacitors operate on the same principle as other types of capacitors. When a voltage difference is applied across two conductors with a dielectric material in between them, it causes an electric field which stores electrical charge. The capacitor stores energy and then releases it when the voltage changes or when the capacitor is discharged over time.

The M550B108K050TG uses a solid polymer-capacitor technology, which is also known as a “hybrid” capacitor. This type of capacitor employs a tantalum anode, an electrolytic polymer cathode and a polymer dielectric. The anode is a thin sheet of etchedanodized tantalum coated with platinum, the cathode is a liquid electrolyte and the polymer dielectric is a solid material. The combination of these components creates a high capacitance ratio, high stability and smooth voltage regulation across various operating temperatures.

The M550B108K050TG and other tantalum-polymer capacitors offer high reliability, and are widely used in modern electronics and appliances. Its small size, light weight and high capacitance make it suitable for space-restricted applications, while its extended temperature range and low ESR enable it to be used in extreme environmental conditions.
