Tantalum - Polymer Capacitors

Tantalum polymer capacitors, also known as “Polymer Tantalum Motors”, are a type of low-profile, high-performance surface-mount capacitors, particularly well-suited for applications related to vibration and shock-resistance. Specifically, TCNO685M016R0500 is a high-end polymer electrostatic tantalum capacitor, boasting a small maximum allowance of selectable capacitance, ranging from 0.001 uF to 47 uF.

When it comes to the operating principle and the application field of TCNO685M016R0500, there is a set of particularities one needs to know before using these capacitors. In essence, TCNO685M016R0500 capacitors are designed to provide an optimal combination of low ESR, high capacitance and high surge current capability, allowing them to meet a wide array of demanding mechanical requirements for various types of applications.

In terms of application field, TCNO685M016R0500 capacitors are particularly suitable for used in military, automotive, hi-rel, computer, consumer and power conversion fields. In addition, they are also known for their ability to support demanding operating temperature ranges down to -55 Celsius.

To better understand the operating principle of TCNO685M016R0500 capacitors, one needs to look at their construction. The capacitor is made of an anode lead, a tantalum anode, a cathode lead and a dielectric layer. The anode lead is made of an electrically conductive material, usually a silver palladium plate; the tantalum anode is usually a porous powder; the cathode lead is typically made of a high-reliability wire; and the dielectric layer is commonly a unique formulation of a highly stable electronic grade polymer.

Essentially, when a voltage is applied across the capacitor, current flows through the material and the capacitor charge is stored in the dielectric layer of the capacitor. The resulting electrical polarization of the dielectric layer creates a space charge, or an electric field, which counters the electric field produced by the voltage that is applied to the capacitor. This space charge is what establishes the capacitance of the TCNO685M016R0500 capacitor.

In addition, these capacitors have a range of other electrical characteristics, such as a reasonably low equivalent series resistance (ESR) and a high self-healing capability. This combination allows the TCNO685M016R0500 capacitor to be used in highly demanding operating conditions and ensures a reliable operation over the wide range of temperature stated before.

In conclusion, TCNO685M016R0500 capacitors are one of the most advanced types from the polymer tantalum capacitors family, boasting unique electrical properties, such as a high capacitance and high surge current capability, and being universally applicable to various vibration and shock-resistant applications.
