Tantalum-polymer capacitors have gained immense popularity in the electronics industry due to its low ESR (Equivalent Series Resistance) and very low leakage current. The capacitors are made by combining a dielectric polymer layer with sintered anodized layers of tantalum powder to form the electrode. The T550B397M015AH capacitor is a tantalum-polymer type, an example of which is the Kemet Tantalum Oxygen Hybrid capacitors.

Application Field of T550B397M015AH

T550B397M015AH are widely used in a variety of electronic circuits, from power management applications in PCs and consumer electronics to medical device designs and automotive systems. The low Equivalent Series Resistance (ESR) values of these capacitors make them ideal for power management applications where their low impedance ensures high quality power supply to the connected devices. Some of the applications in which these capacitors are used include:

• Power supply filtering for motherboards
• Computer peripherals
• Television power supplies
• LCD TV video cards
• Audio equipment
• Automotive power systems
• Low noise amplifiers
• Pulse generators

The capacitors are also used in military and aerospace applications; especially in shock-resistant and high-vibration environments as they are known for their lower susceptibility to moisture, temperature and vibration compared to traditional electrolytic capacitors.

Working Principle of T550B397M015AH

T550B397M015AH capacitors function in much the same way as any traditional capacitor. When a voltage is applied across the capacitor terminals, an electric field is created between the anode and cathode electrodes. This electric field creates an electric charge that is stored in the capacitor. As the applied voltage is increased, so does the amount of charge that is stored in the capacitor and the resultant capacitance.

The primary difference between the T550B397M015AH capacitor and other traditional capacitors is in the dielectric material that is used. The capacitors use a thin layer of tantalum powder combined with a polymer material to form the dielectric, offering a number of advantages compared to traditional capacitors. The main advantages of these capacitors are:

• Low Equivalent Series Resistance (ESR) compared to traditional capacitors
• Low leakage current
• Excellent stability over a wide temperature range
• High pulsed current capability
• Superior tolerance to shock and vibration

The combination of low ESR, low leakage current and excellent stability makes the T550B397M015AH capacitor an ideal choice for a wide range of power management applications. Its low leakage current ensures that the system’s power is not wasted, and its excellent stability makes it ideal for high shock and vibration applications.
