• Power Electronics: This is a broad area of research which encompasses power conversion, control, and transmission. T86C685M020EASL are widely used in this application due to their high capacitance, low leakage, and high tolerance diversity.
• Consumer Electronics: T86C685M020EASL are often found in consumer electronic products such as medical devices, cameras, and TVs. Due to their low cost, long life, and reliability, they are an ideal choice for applications where frequent replacement of components is not desirable.
• Hi-Fi Audio Systems: The T86C685M020EASL is an ideal choice for audio systems due to their high capacitance and low ESR (equivalent series resistance). This makes them ideal for noise reduction and signal filtering applications.
• Lighting: Due to their high capacitance and low leakage, T86C685M020EASL are often used in lighting control systems. The high capacitance allows for a larger amount of current to be stored, while the low leakage enables a long life for the capacitor.
• Automotive Systems: The reliability and high capacitance make T86C685M020EASL an ideal choice for automotive applications. These capacitors are often used in engine control systems, power steering systems, and ABS systems due to their ability to handle high temperatures and vibration.

Working Principle of T86C685M020EASL

T86C685M020EASL are polarized capacitors. This means that they only work in one direction, and the positive and negative terminals must be connected properly. This is due to the construction of the capacitor, which consists of 3 main components; the anode, cathode, and electrolyte. The anode and cathode are made of tantalum, and the electrolyte is made of an oxide layer. When a positive voltage is applied, electrons flow from the cathode to the anode, and the capacitor charges. When a negative voltage is applied, electrons travel from the anode to the cathode, and the capacitor discharges.

The main advantage of tantalum capacitors is their high capacitance per unit volume, relative to other types of capacitors. This is due to the thin oxide layer which is used as the electrolyte. This allows the T86C685M020EASL to store more charge in a smaller space than other types of capacitors.

Tantalum capacitors are also very reliable and able to withstand high temperatures and vibration. This makes them particularly suitable for automotive applications, where reliability is paramount. The high temperature ratings of tantalum capacitors also makes them ideal for many modern electronic applications.

Finally, tantalum capacitors also have a low ESR. This means that the capacitor will retain its capacitance even at higher frequencies, making it ideal for filtering applications.

In conclusion, the T86C685M020EASL has many advantages which make it an ideal choice for many modern electronic applications. It has high capacitance, low leakage, and a high temperature rating, making it a reliable and cost-effective solution for many applications. The main applications are in power electronics, consumer electronics, hi-fi audio systems, lighting, and automotive systems.
