Tantalum Capacitors

A tantalum capacitor is a type of electronic component that has an anode composed of a sintered pellet of tantalum, sandwiched between two layers of carbon. It is a polarized capacitor that, like all capacitors, is used mainly to store energy in a circuit. A 173D336X9025YWE3 is an example of a tantalum capacitor.

Application Field

Tantalum capacitors have a wide range of uses in modern electronics circuitry. These capacitors are mainly used in DC/DC converters, touchscreens, and advanced audio and video equipment. Additionally, they are used in processor-controlled power supplies, medical diagnostic and treatment equipment, digital and analog boards, transformerless amplifier circuits, power supplies, and other consumer electronic devices.

The advantages of using tantalum capacitors are in their low costs, higher stability, low leakage, and low-resistance features. They are also good at suppressing EMI and are suitable for a variety of application scenarios.

Working Principle

The power currently passing through a circuit is stored in the tantalum capacitor\'s anode, which is a pellet of tantalum metal. When a voltage is applied to the capacitor, it forms a capacitance and stores charge. When the voltage drops, the stored energy is released, resulting in charge flowing through the circuit.

The 173D336X9025YWE3 is an example of a surface-mount tantalum capacitor. The device is constructed with a tantalum pellet anode and two layers of carbon. Additionally, there are two terminals on the capacitor. When the terminals are connected, a voltage is applied to the device and it starts to store energy. Once the energy is stored, the voltage is removed, causing the charged device to release its stored energy.

Tantalum capacitors are highly efficient and reliable components for circuit design. As the name suggests, they use tantalum as the anode, which is a relatively inexpensive metal with great properties. As such, these capacitors are suitable for a variety of applications, making them essential components in modern electronics.
