Tantalum capacitors are small, high-capacity components used in many electronic devices. They are typically used in consumer and industrial applications where low voltage and high resistance are required. A common example is the tantalum capacitor type 109D686X9100T2.

The 109D686X9100T2 is a chip-type, non-polarized, axial-leaded electrolytic capacitor. It has an operating temperature of -55°C to +125°C and a rated voltage of 6.3V. The capacitance range of this particular type is 100 – 680µF. This device is often used in applications requiring stable voltage output, such as displays, LED lighting, and the like.

The 109D686X9100T2 capacitor is constructed with two metallic plates that are covered with a dielectric material and sealed in a metal case. A small amount of electrolyte is added to create an electric field that increases the capacitance. The charge is stored in a thin layer of oxide dielectric between the plates, and this layer must remain intact for proper function.

The working principle of the 109D686X9100T2 capacitor is simple. When a voltage is applied to the capacitor’s plates, electrons flow between the plates, creating an electric field. This electric field holds the electrons in place, thus creating a “pool” of charge, hence the name “capacitor.” When a current is applied, the charge “evaporates,” resulting in a current travelling across the plates.

The 109D686X9100T2 tantalum capacitor is suitable for use in various applications such as power management, voltage regulation, and decoupling. They are traditionally used in battery-backed systems, where they can provide stable voltage output. They are also used in motherboards, computer communication systems, medical instruments, and many other electronics that require a stable source of energy.

In summary, the 109D686X9100T2 capacitor is a non-polarized, axial-leaded capacitor with an operating temperature of -55°C to +125°C and a rated voltage of 6.3V. Its capacitance range is 100 – 680µF, making it suitable for applications such as power management, voltage regulation, and decoupling. It works by creating an electric field between two metallic plates that are covered with an oxide dielectric, resulting in a “pool” of charge that can be used to provide a stable source of energy when needed.
