T86D156M025EAAL is part of the tantalum capacitor family. Because of its unique combination of high reliability and small size, it is widely used in a range of electronic applications. Its working principle is based on the electrochemical properties of tantalum, which allows it to hold a charge even after the power source is disconnected. The applications of this Tantalum capacitor range from personal electronics to highly sophisticated electronic equipment.

General Information About T86D156M025EAAL

The T86D156M025EAAL is a molded type, conformally-coated, dry (no electrolyte) tantalum capacitor that operates at a rated temperature of 85 °C. It is composed of a sintered anode in the form of a semiconductor body, a manganese dioxide (MnO2) dielectric oxide layer, and a tantalum foil as the cathode. The anodic surface is then applied with a conformal coating, which is either in the form of a polyester or polysiloxane film. These capacitors can be soldered or welded onto the mounting board or into a slot provided for it. Since there is no electrolyte, the manufactured products are more reliable than its counterparts with electrolyte and they also have a longer life.

Features of T86D156M025EAAL

T86D156M025EAAL capacitors are mainly chosen for their incredibly small size; their surface mount design makes them ideal for applications that require space saving. They possess a wide temperature range and a high capacitance and voltage for their size. The dielectric oxide is highly stable, provides improved device reliability, and offers a high voltage capability. The low ESR (Equivalent Series Resistance) of tantalum capacitors makes them preferred for use in high frequency switching power supplies.

Advantages of T86D156M025EAAL

T86D156M025EAAL has many advantages over other types of capacitors. They are very small and have an excellent voltage and capacitance per unit volume ratio. This makes them very suitable for space-constrained applications, such as small handheld devices. They also have a high voltage-temperature coefficient, which makes them suitable for use in high frequency switching power supplies. Additionally, these capacitors have very good insulation resistance and low leakage current, which improves the reliability of the device.

Application Field of T86D156M025EAAL

The T86D156M025EAAL is a suitable choice for those applications which require a small size capacitor and high reliability. Its wide temperature range and high capacitance make it suitable for many electrical and electromagnetic applications. It can be used in power supplies, filters, high voltage DC-DC converters, electronic circuit switching, clock and data line protection, etc. Additionally it has been approved by UL, CSA, VDE, CE, and other international safety agencies.

Working Principle of T86D156M025EAAL

The working principle of the T86D156M025EAAL is based on the electrochemical properties of Tantalum. When the capacitor is connected to a power source, it allows an electric current to flow between the anode and the cathode, creating an electric potential, or charge, across the oxide layer. This charge is stored in the capacitor and will remain even after the power source is removed. When the capacitor is needed to transfer energy again, a current is allowed to flow and the energy stored in the capacitor is released.

Conclusion

The T86D156M025EAAL can be used in a wide range of electronic applications. Its ultra small size and high reliability make it a very suitable choice for space-constrained applications, such as portable devices. It is highly resistant to temperature and vibration, and has a long life due to its dry composition. Furthermore, it is approved by many international safety agencies. Understanding the working principle of this tantalum capacitors can help you better use these components in your circuit.
