Tantalum capacitors are widely used in applications from consumer electronics to government and military systems. The M39003/03-0434 is one of the most popular of these capacitors and is used in many types of applications. In this article, we will discuss the M39003/03-0434 application field and working principle.

M39003/03-0434 Application Field

The M39003/03-0434 is a surface mount, non-polarized, tantalum capacitor. It is available in a variety of sizes and capacitance values. This capacitor is commonly used in consumer electronics, including laptop computers, smartphones, and audio equipment. It is also used in military and aerospace applications due to its size and ability to handle high temperatures. This capacitor is ideal for high-reliability applications where space is at a premium.

Working Principle

Tantalum capacitors work on the principle of electric double-layer capacitance. When a voltage is applied to two electrodes, the tantalum oxide layer between them forms two capacitive plates. This creates an electric field that stores energy in the form of electrical charge. The stored electrical energy can be discharged by connecting the two electrodes when the capacitor is used in a circuit.

Tantalum capacitors are also unique due to their very low leakage current. This low leakage current allows for longer life and less susceptibility to temperature fluctuations. The capacitors also have higher capacitance and lower series resistance than other capacitors, making them more suitable for high-frequency applications.

Conclusion

The M39003/03-0434 tantalum capacitor is a popular choice for applications in consumer electronics, military and aerospace systems. It works on the principle of electric double-layer capacitance, and has very low leakage current, making it a reliable choice. Its small size and high capacitance make it ideal for high-frequency applications where space is at a premium.
