Tantalum Capacitors are one of the most widely used types of capacitors. They have been used for decades in a wide range of electronics applications, particularly for filtering power supply noise or providing short-term energy storage. The technology has evolved over the years, and today capacitors with greater voltage ratings, higher capacitance and better frequency response are available. But what is the application field and working principle of the ubiquitous part code: 199D107X96R3D6V1E3?

The first three characters of the part code, 199, refer to the size of the capacitor. In terms of volume, this is the largest size of Tantalum cap available. The D indicates that the capacitor is a radial device, meaning that the leads are bent out from the sides. This particular capacitor has a radial pitch of 2.5mm. The nominal capacitance of this particular part is 107µF, as indicated by the X in the code. Its voltage rating is 6.3V, as indicated by the R, and its temperature coefficient is -30%, which is indicated by the 3 in the code.

As for the capacitor’s application field, a Tantalum capacitor is ideal for use in applications where space is at a premium. Its small size and low profile makes it perfect for applications where size and weight are considerations, such as consumer electronics, automotive electronics, and even medical and aerospace applications. Moreover, its long shelf life and solid-state construction make it highly reliable.

The working principle of a Tantalum capacitor is based upon a process called “dielectric annealing”. The capacitor is composed of two electrodes. The inner one is an anode, and the outer one is a cathode. Both are made of metal, typically tantalum and titanium. When a voltage signal is applied to the capacitor, positive charge accumulates on the anode and negative charge accumulates on the cathode. As a result, the particles between the two electrodes are drawn toward the anode, creating a dielectric annealing action that increases the capacitance.

The increased capacitance imparts several benefits for the capacitor. For example, it helps to reduce power supply noise, allowing the capacitor to filter out ripple or high frequency signals. Additionally, it increases the capacitor’s storage capacity, allowing it to store more energy for a longer duration. This is ideal for both general circuit applications and temporary energy storage.

Overall, capacitors with the part code 199D107X96R3D6V1E3 have a wide variety of applications and benefits. Their small size, low profile, long shelf life and solid-state construction make them ideal for a range of applications, including consumer electronics, automotive, medical, and aerospace. Moreover, their increased capacitance imparts several benefits, including reduced noise and increased energy storage capacity.
