Tantalum Capacitors

A tantalum capacitor is a type of capacitor with an anode made up of tantalum, a metal with a high melting point. This capacitor is a polarization-dependent device with a characteristic structure consisting of two highly conductive electrodes separated by an ionic-conductive dielectric material made of either polypropylene, polyesters or polycarbonates. The tantalum capacitor is widely used in electronic circuits due to its low equivalent series resistance (ESR) and good temperature stability.

The anode of a tantalum capacitor is made of a relatively pure form of tantalum metal. This is usually fabricated in the form of an oxide. The anode is then placed into an electrolytic solution made up of potassium hydroxide or other electrolyte. This electrolyte solution serves as the medium through which a current flows when a voltage is applied across the capacitor. The cathode of the tantalum capacitor can either be made of aluminum or some other conductive material.

The most commonly used code to refer to a tantalum capacitor is the part number 199D106X0016C5B1. This part is used in various applications across many industries including medical, automotive, and consumer electronics. It is a leaded device with a capacitance value of 16μF and an ESR of 1.7 Ohms. Its rated voltage is 10V, and it is capable of operating up to 70 degrees Celsius. The 199D106X0016C5B1 is suitable for applications with high ripple currents, where its high ESR capability offers improved design flexibility.

The working principle of a tantalum capacitor is based on the electrolytic capacitor. When a voltage is applied across the capacitor, current flows from the anode to the cathode creating an electrochemical reaction between the two electrodes. This reaction in turn creates an electric field which is responsible for storing the electric charge in the capacitor. The stored energy is then released when the capacitor is discharged back into the circuit. Due to the electrolyte, the anode\'s dissociation and diffusion are fast, making a tantalum capacitor an ideal choice for applications which require quick charging and discharging rates.

In conclusion, a tantalum capacitor is an ideal choice for applications with high ripple currents, providing improved design flexibility and a relatively low ESR. With its high melting point and high energy density, it is an attractive choice due to its excellent temperature stability. The part 199D106X0016C5B1 is the most commonly used code to refer to a tantalum capacitor and can be found in a range of applications including medical, automotive, and consumer electronics.
