Tantalum - Polymer Capacitors

TCJD477M002R0050 is a type of capacitor made with tantalum and a polymer. This type of capacitor is most often used in audio applications and where voltage stability is critical. They are known for their superior reliability, small size and high capacitance, making them ideal for many applications.

Application Field

Tantalum - polymer capacitors are widely used in a variety of devices, both consumer and industrial. They are commonly found in:

• High volume consumer audio products like portable music players and gaming consoles.
• Power supplies and alternating current circuits.
• Power amplifiers, digital signal processors and integrated circuit chips.
• Communication and control equipment.
• Portable and mobile radios.

The small size, high capacitance and superior reliability of tantalum - polymer capacitors make them ideal for high volume, low power applications. In these applications, the components can have a long lifespan and the compact size allows for the device to be very efficient.

Working Principle

The working of these capacitors is dependent on the action of electric fields created between the two electrode layers. The electrodes, one made from nickel and the other from titanium, are connected to the one or more tantalum pellets inside the capacitor. When voltage is applied across the capacitor, the electrostatic attraction between the electrodes and the pellets creates a current. The current then travels through the pellets, allowing the capacitor to store energy.

During discharge, the ripple voltage is absorbed and the capacitance diminishes. As the current continues, the charge on the pellets decreases until it reaches equilibrium with the applied voltage. This is what creates the stability of voltage in this type of capacitor.

The tantalum - polymer capacitors offer many advantages over traditional aluminum electrolytic capacitors. They have superior range of operating temperatures, superior power handling and superior thermal stability. They also require less input current and have higher capacitance.
