Tantalum capacitors, also known as tantalum electrolytic capacitors, use an electrolyte to absorb the charges, form an electric field, and thus provide capacitance. This capacitor is made of tantalum metal powder, an oxide layer, and a liquid or solid electrolyte. A small amount of impurity is added to the oxide layer to form semiconductor properties. The TLCR686M004RTA is one form of tantalum capacitor, and it has a wide range of applications and a distinct working principle.

Applications of the TLCR686M004RTA

The TLCR686M004RTA is a surface mounted tantalum capacitor with a voltage rating of 6.3 VDC, and has a high capacitance value of 6.8µF. It is widely used in portable and handheld electronic devices, such as mobile phones, PDAs and very low voltage DC-DC converters. The tantalum capacitor can also be used for clock circuits, broadband filters, and low ESR noise reduction. It is often used in automotive applications as well, such as in ABS brake systems and digital dashboards, as it is well suited for stability and high temperature performance.

Working Principle of the TLCR686M004RTA

The TLCR686M004RTA works by using a thin layer of tantalum pentoxide or tantalum oxide as a dielectric material, and an electrolyte as a charge storing medium. The most common electrolyte used is potassium hydroxide, but other organic and inorganic liquids can also be used. The surface of the tantalum plates is coated with a solid electrolyte which assists in the movement of electrons on the surface of the plates. A small amount of impurities are added to the tantalum oxide to form semiconductor properties and to reduce the dielectric strength of the material.

The capacitor’s working principle is as follows: when the capacitor is connected to a power supply, a current passes through the external plates and into the electrolyte, thus creating a potential difference between the plates. This potential difference creates an electric field within the capacitor, enabling electrons to move freely between the plates of the capacitor. As the current passes through the capacitor, the charge is stored and a current flows through the circuit.

Additionally, the capacitor features a wide temperature range, allowing it to operate in temperatures ranging from −55°C to +125°C. The capacitor has a low ESR, or equivalent series resistance, which is ideal for low noise applications. It also has a low ESL, or equivalent series inductance, which allows it to operate at higher frequencies.

Conclusion

The TLCR686M004RTA is a surface mounted tantalum capacitor with a voltage rating of 6.3 VDC and a capacitance value of 6.8µF. It is used in a wide range of applications, such as portable and handheld electronic devices, automotive applications, clock circuits, broadband filters, and low ESR noise reduction. The capacitor has a wide temperature range, a low ESR, and a low ESL, which makes it the ideal choice for low noise applications.
