Tantalum-polymer capacitors, also known as Ta-polymer capacitors, are advanced electrolytic capacitors that take advantage of the extremely high capacitance of certain organic polymers films. Combining these films with a tantalum anode is the basis of the design of Ta-polymer capacitors. Compared to traditional electrolytic capacitors, Ta-polymer capacitors offer excellent capacitance values, low ESR, low leakage current, and oil-like dielectric strength. These properties make them an excellent solution for many applications in the electronics and telecommunication industries.One of the most popular Ta-polymer capacitors available on the market today is the TCNL476M016R0250. It is a non-inductive, surface-mountable aluminum-electrolytic capacitor with improved capacitance and low ESR values. The capacitor is encapsulated in an epoxy resin construction, which provides excellent mechanical strength and reliable performance. It has a rated voltage of 16V and a rated capacitance of 0.026uF. It also features a -55°C to +125°C operating temperature range, and offers low ESR values at high frequencies.The TCNL476M016R0250 is ideal for use in a variety of applications, including high-frequency bridge circuits and ripple filters, smoothing power supplies, motor control circuits, and device protection circuits. Its low ESR values make it well-suited for use in applications requiring low AC impedance and good ripple current performance. It is also well-suited for use in high-frequency switching regulators, battery protection, and many more applications.As for its working principle, Ta-polymer capacitors use a tantalum anode and a special organic polymer film as the dielectric. The organic polymer film is formed from the electrochemical deposition of a polymer on the tantalum anode. The electrochemical deposition process produces multiple layers of the organic polymer film, which creates a high dielectric constant. This organic polymer dielectric layer is separated from the anode by an electrolyte, which is usually an aqueous solution.When a voltage is applied across the terminals, the electric field produced causes electrons to diffuse through the electrolyte and onto the anode. The electrons build up a charge on the anode and this creates an electrostatic force between the anode and the organic polymer film dielectric layers. This force produces an electrical field that translates into a capacitive effect, storing energy.As the voltage increases, the capacitive effect increases accordingly. This means that the same Ta-polymer capacitor can provide significantly higher capacitance values than typical electrolytic capacitors. In addition, since Ta-polymer capacitors are non-inductive, they also have a larger widest useful frequency range and reduced resonance points. This makes them ideal for use in high-frequency applications.Overall, the TCNL476M016R0250 Ta-polymer capacitor is an excellent choice for a variety of electronic and telecommunication applications. It offers superior performance, due to its excellent capacitance and low ESR values, as well as its wide operating temperature range and non-inductive construction. Its robust polymer dielectric layer and electrolyte provide reliable and consistent performance, while its low resonance points make it suitable for use in high-frequency applications. By taking advantage of the benefits offered by this type of capacitor, engineers can ensure they are making the best use of their components in their circuits.
