Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor, a component of electronic circuits. They are made of tantalum metal which acts as an anode, with an electrolyte cathode. The electrolyte forms a film on the anode providing the dielectric layer for the capacitor. They are widely used in electronic equipment due to their small size and wide operating temperature range.

The M39003/03-0245/HSD is an individual highly reliable hermetically sealed encased tantalum capacitor available in a range of capacitances. It has excellent volumetric efficiency up to 500V and comes along with a trim capacitor connected as a series feed-in to give an additional margin of safety.

Application Field

The M39003/03-0245/HSD is ideal for use in communications systems, in particular for intermediate frequency stages, where high isolation and peak pulse performance is not a requirement. It is also commonly used in DC/DC converters and other applications that require a large capacitance range. This type of capacitor is available for both through-hole and surface-mount applications, making it a very versatile and reliable component.

Working Principle

The M39003/03-0245/HSD capacitor is based on tantalum construction technology. Its internal structure consists of a metal substrate, an insulation film and a metal electrode. The capacitor is sealed with a glass-filled epoxy resin material. This sealing ensures that the capacitor is air-tight and corrosion-proof. The capacitor also has a trim capacitor connected in series, increasing its effectiveness in certain areas.

When AC voltage is applied, a dielectric film forms between the two metal electrodes. This increases the charge that the capacitor can handle, and also allows more current to pass through the capacitor without overheating or damaging the device. In this way, the capacitor can store energy and act as an energy reservoir. This type of capacitor has a higher capacitance than electrolytic or film-based capacitors and is therefore able to store more energy.

Tantalum capacitors are also more reliable and less prone to failure than other types of capacitors. They are able to maintain their capacitance over a much wider range of temperatures, making them suitable for use in a variety of extreme environments. The M39003/03-0245/HSD is also designed with an additional trim capacitor providing an additional safety margin.

The M39003/03-0245/HSD is an ideal component for applications where high reliability and high capacitance are required. Its wide operating temperature range, small size, and extended shelf life make it a highly reliable component suitable for a wide variety of applications.
