Tantalum Capacitors

Tantalum capacitors are a type of capacitor created from tantalum metal. They offer high circuit density, low equivalent series resistance (ESR), and high operating frequency capabilities, making them ideal for a wide variety of applications.TACR685K006R capacitors, in particular, are a type of tantalum capacitor primarily used for high efficiency and high frequency applications.

Application Field

TACR685K006R capacitors are used for a variety of high frequency, high efficiency applications including:-Regulated power supplies-DC-DC converters-Voltage converters-Power converters-High-stable oscillators-Noise and switching suppression-High power LED lighting-Pulsed laser systems-Measuring and monitoring systems-Small telecommunications systems-High-frequency RF modules-Automated test systems-Switch-mode power suppliesTACR685K006R capacitors are also widely used in automotive applications such as low and high voltage inverters, spark ignition control systems, and more.

Working Principle

TACR685K006R capacitors are solid electrolytic capacitors, meaning that they use a solid electrolyte layer of a conducting material as the dielectric insulator between the two metal plates of the capacitor. The metal plates are made from tantalum, a type of metal with high electrical and thermal conductivity. The tantalum plates, connected internally to a lead frame, are wholly immersed in a solid electrolyte such as an organic solvent containing ions. These ions carry the electrical charge between the metal plates. The characteristics of the TACR685K006R capacitors, and other tantalum capacitors, are based on the capacitance, temperature, operating voltage, and ESR offered. Due to the use of high-electrolyte solvents and tantalum plates, TACR685K006R capacitors are able to offer high capacitance with low ESR at high temperatures, making them highly suitable for high-efficiency applications.

Capacitance

TACR685K006R capacitors are rated with a capacitance of 6.85 µF in the range of 0.5⅔Hz to 1MHz. It is important to note that the capacitance of TACR685K006R capacitors is higher than smaller capacitors, which is one of the reasons why they are used in high efficiency applications.

Operating Voltage

The operating voltage of TACR685K006R capacitors can range from 10V to 50V, depending on the application. It is important that the operating voltage is sufficient to power the components of the circuit, as higher operating voltage can reduce the lifespan of the capacitors.

Temperature

The rated operational temperature of TACR685K006R capacitors is +105°C. The temperature of the environment should not exceed this temperature, as higher temperatures can reduce the lifespan of the capacitors.

Equivalent Series Resistance (ESR)

The ESR of TACR685K006R capacitors is very low, typically in the range of 60mΩ. Low ESR means that the capacitor is able to offer high efficiency, which is why it is used for applications such as switch-mode power supplies.

Conclusion

TACR685K006R capacitors are a type of tantalum capacitor primarily used for high efficiency and high frequency applications. They offer high circuit density, low ESR, and high operating frequency capabilities, making them ideal for a wide variety of applications. They are widely used in automotive applications as well as strong industrial applications such as: regulated power supplies, voltage converters, and more. TACR685K006R capacitors are rated with a capacitance of 6.85 µF, a temperature of +105°C, and an ESR of 60mΩ. Due to their high capacitance, low ESR, and low temperature, they are highly suitable for high-efficiency applications.
