Tantalum capacitors, also known as tantalum electrolytic capacitors, are a specialized type of capacitor. They are some of the most efficient compact capacitors used for frequencies up to around 500 MHz. The two main types of tantalum capacitors are either solid or wet (an electrolytic version). M39003/03-0146/HSD capacitors belong to the solid tantalum capacitors category.

A tantalum capacitor is an electronic component that contains two electrical plates separated by an oxide dielectric layer. The anode is usually made from high-grade tantalum metal, while the cathode is typically made from conductive carbon or titanium. This type of small capacitor has a very low voltage drop due to its unique design. They are commonly used for timing and ripple applications in high-speed digital circuits, and for voltage filtering in power management systems.

The M39003/03-0146/HSD capacitor is designed to operate at high frequencies, up to 500 MHz. It is a 6 mm x 5 mm, two element, solid capacitor that offers high capacitance values in an extremely small package. The small size and low profile of the M39003/03-0146/HSD capacitor allow it to be used in tight spaces, making it ideal for a variety of electronic applications. The capacitor has a rated capacitance range of 12.0 to 2.2 µF, and a rated voltage of 10 V.

The working principle of a solid tantalum capacitor is based on the electrical properties of tantalum, which has a high electrochemical stability and relatively low reactivity with air and other gases at moderate temperatures. By applying a voltage to the capacitor’s terminals, an electrical field is created in the oxide layer of tantalum between the anode and cathode. This field causes an electrochemical reaction in the oxide layer, forming a monolayer of electrically-conductive molecules on the anode and cathode. The electrochemical reaction also increases the size of the oxide layer, causing the capacitor to store more energy and reduce the electrical resistance of the structure.

The M39003/03-0146/HSD capacitor has excellent stability in temperature extremes, making it suitable for applications in environments where temperatures can vary significantly. It also offers exceptional levels of reliability, with a very long life expectancy and low risk of component failure. The component offers excellent dielectric strength, low parasitics, low current leakage, and low self-inductance, making it well-suited for use in high-speed, high-amplitude circuits. Additionally, the capacitor is relatively inexpensive and easy to install, making it an ideal choice for a wide variety of applications.
