Tantalum capacitors are electronic components widely used in the communication, medical and military industries. The M39003/03-0487H is a part of the M39003/03 series of radial-lead, silicone-dipped, solid tantalum capacitors. They are used to store energy or maintain a voltage level in an electronic system.

Although every device has its unique design, tantalum capacitors typically have two metal plates with an insulator between them. This configuration forms a capacitor dielectric, which is the medium used to separate and store energy. The amount of energy that can be stored is determined by the size and design of the capacitor, as well as its construction.

The M39003/03-0487H combines the characteristics of the common M39003/03 series with additional features. It has a smalld-footprint and high-temperature performance, as well as tighter leakage current limits. These features make the capacitor well-suited for applications that require high reliability and long-term stability over a broad temperature range.

This device is designed for a wide range of applications, including military and medical systems. It is designed for use in filters, high-frequency oscillators, digital-to-analog converters and energy storage devices. It is best used in systems where reliable voltage hold-off and temperature stability is critical.

The M39003/03-0487H capacitor is also designed to address the most common failure modes of tantalum capacitors, including humidity and vibration. It utilizes a conformal coating to limit exposure to environmental contaminants. This coating is designed to protect against chemical and mechanical stress, such as vibration and shock.

The working principle of a tantalum capacitor is relatively simple. When a direct current (DC) voltage is applied across the device‘s leads, electrodes in the capacitor are polarized, forming a dielectric field between them. The dielectric field stores the energy and is essentially a source of stored energy.

The M39003/03-0487H features a wide operating temperature range from -55°C to 125°C. It also features an industry-leading low dynamic impedance. The combination of these features makes the device well-suited for use in critical military or medical applications.

In conclusion, the M39003/03-0487H is an advanced tantalum capacitor designed for use in highly reliable, temperature-sensitive applications. Its unique features, such as high-temperature performance and low dynamic impedance, make it the ideal choice for military and medical applications. The working principle of a tantalum capacitor is relatively simple and reliable, providing a reliable source of energy storage.
