Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolyte capacitors, are a type of electrolytic capacitor. They were first developed in the first half of the 20th century and are today widely used in electronic systems due to their relatively small size, low leakage current, stable capacitance, and long lifetime. They are composed of two electrodes (anode and cathode) separated by an insulating dielectric layer, typically made of tantalum pentoxide. The anode electrode is typically made of a porous sintered tantalum core which is then soaked with an electrolytic solution.

The M39003/09-3007H, a type of tantalum capacitor, is a variable electrolytic capacitor. It is composed of a cylindrical tantalum anode with a porous structure along with an opposing thin-film dielectric layer. The capacitor has a voltage rating of 2.5V to 16V and a maximum capacitance of 33μF. The capacitor is perfect for low-frequency applications such as power supplies, signal waveform shaping, and filter networks.

The primary advantage of the M39003/09-3007H is its low-leakage current. This makes it well-suited for applications where low leakage current is essential, such as in low-power circuitry and ultra-low-power circuitry. The capacitor’s wide capacitance range makes it useful for a variety of applications, including those involving signal waveform shaping, low-frequency filtering, and power supply regulation.

The working principle of the M39003/09-3007H is simple. When a voltage is applied across the terminals of the capacitor, the dielectric layer between the two electrodes is compressed. This compression increases the capacitance of the capacitor, allowing it to more effectively store energy. Over time, the stored energy is slowly released into the circuit, and the capacitance decreases until the dielectric layer is again compressed. The capacitor then begins to re-charge, thus repeating the process.

The M39003/09-3007H is a highly reliable and versatile capacitor that is perfect for a variety of applications. Its low-leakage current and wide capacitance range make it a useful component for ultra-low-power and low-power circuitry. Additionally, the capacitor’s small size makes it easy to include in complex designs. The M39003/09-3007H is a great choice for any application requiring a reliable and long-lasting tantalum capacitor.
