Tantalum Capacitors

Tantalum capacitors are types of electrolytic capacitors that use tantalum metal as the anode and have a wet electrolyte solution as the cathode. They offer extremely high capacitance values in small sizes and high operating temperatures over 100 degrees Celsius.Tantalum capacitors offer several unique advantages over other types of capacitors such as ceramic capacitors. They have low leakage current, high energy density, higher current carrying capability, high frequency performance, and low equivalent series resonance. They also have superior temperature and voltage stability, making them ideal for use in high temperature environments.Due to their unique properties, tantalum capacitors are used in a wide range of applications including power management, automotive electronics, medical devices, and consumer electronics.

13008-021MESB/HR application field and working principle

The 13008-021MESB/HR is a surface-mount tantalum capacitor. It is designed to provide high capacitance in a relatively small package, making it suitable for applications such as laptop computers, cell phones, and other portable electronics. It has a voltage rating of 35V and a capacitance range from 1 to 47uF.

The capacitor works by utilizing the dielectric properties of tantalum oxide. A thin film of oxide is deposited onto the anode contact and the electrical field formed across the oxide layer stores energy in the form of an electrostatic capacitor when current is applied. When current is applied to the capacitor a voltage potential is created across the plane of the oxide layer and charges the capacitor. The voltage potential creates an electric field in the oxide layer that stores charge on the anode and cathode contacts. The electric field stores energy in the oxide layer until the capacitor is discharged, allowing for the use of high levels of capacitance in a small device.

The 13008-021MESB/HR can be used for a variety of applications such as Signal Blocking, Smoothing, and Filtering. It is designed to handle high current levels and temperatures up to +125 degrees Celsius, making it suitable for use in harsh environments. The capacitor is also RoHS compliant, meaning it is free of hazardous materials like lead and cadmium, making it safer and more environmentally friendly.

In summary, the 13008-021MESB/HR is a surface mount tantalum capacitor that offers high levels of capacitance in a small package. It is designed to handle high current levels and high temperatures, making it suitable for use in a wide range of applications including signal blocking, smoothing, and filtering. Furthermore, the capacitor is RoHS compliant, making it safer and more environmentally friendly.
