Tantalum capacitors are a form of electrolytic capacitor, made with a tantalum powder metal anode and an electrolytic manganese dioxide cathode with an organic polymer as the electrolyte. These passive components are widely used in electronic circuits because of their high specific capacitance, low loss, long life, and their ability to be miniaturized. The TPSF686M016R0200 is a type of surface mount tantalum capacitor.

This specific capacitor has a capacitance of 6.8 µF (+/-20% tolerance) at a maximum operating voltage of 16V. Additionally, it has a maximum leakage current of 0.02 µA with a temperature range of -55°C to +125°C, with the peak of the derating curve beginning at 105°C. It has a working frequency range of 0 to 10 MHz.

The TPSF686M016R0200 capacitors feature a conformal coating which helps to protect against environmental hazards such as humidity which can cause corrosion. Additionally, this capacitor features a solid (non-conductive) electrolyte which helps to increase the capacitor’s life cycle. The lead spacing is 0.5 mm which requires a precise placement during the assembly process.

The most common application of the TPSF686M016R0200 capacitors is in power supplies and power management circuits. Generally, these capacitors are used in areas where higher capacitance and operating voltages are needed. Specifically, this type of capacitor is used to decrease the ripple voltage in power supplies, to increase the confidence of the circuit, and to filter high frequency noise.

The working principle of the TPSF686M016R0200 capacitor is relatively simple. With a direct current (DC) voltage across two metal plates (anode and cathode), an electric field is created within the capacitor. When the electric field penetrates and fills the space between the metal plates, an electrical charge is stored in the capacitor and capacitance is the result. This stored electrical energy is stored and released when required.

The increase or decrease of electrical charge placed on the capacitor’s plates, will lead to a corresponding increase or decrease of capacitance. In other words, when the voltage across the capacitors plates is increased, the capacitance will increase as well. However, when the voltage is decreased, the capacitance also decreases.

It is important to note that the TPSF686M016R0200 capacitor will not remain in its charged state for prolonged periods, as it will slowly discharge itself over time. This process is known as leakage and is a common issue with all capacitors.

In conclusion, the TPSF686M016R0200 capacitor is a surface mount tantalum capacitor that is designed to be used in power supply and power management circuits. With its 16V rating and 6.8 µF capacitance, it is perfect for applications where high capacitance and operating voltages are required. Additionally, the solid (non-conductive) electrolyte and conformal coating provide increased life cycle and protection against environmental hazards.
