4TCE330M Capacitors

Tantalum - Polymer Capacitors

A tantalum - polymer capacitor (TPC) is a type of capacitor that uses tantalum metal as one of its electrodes, with a polymer as the dielectric. TPCs offer numerous advantages over traditional electrolytic or ceramic capacitors, including higher energy density, higher capacitance stability, better temperature performance, and better stability. The 4TCE330M is a high capacitance, high voltage, TPC designed for applications requiring long life and reliable performance in harsh environments.

4TCE330M Application Fields and Working Principle

The 4TCE330M is a multi-functional, low-loss, multi-layer, and high-reliability capacitor. It is widely used in high-frequency and high-load circuits. It has excellent performance in ultra-high frequency regions and also provides good frequency coverage in short wave frequencies and microwaves. The 4TCE330M is extensively used in automotive electronics, industrial electronics and telecommunications equipment.

The 4TCE330M utilizes a unique construction process to increase its stability and reliability. The main part of the capacitor is a composite dielectric consisting of porous tantalum and a carbon filled electro-conductive polymer. The tactalum layer absorbs the electro-conductive polymer, while the electro-conductive polymer layer stabilizes and constrains the electric field during operation, thus providing a more robust and predictable electrical performance.

At the same time, the carbon filler in the electro-conductive polymer gives the 4TCE330M increased thermal conduction and heat dissipation, leading to improved reliability and life-span of the capacitor. Further, the multi-layer structure of the 4TCE330M enhances the capacitor’s robustness under extreme temperatures and pressure conditions.
