Tantalum - Polymer Capacitors

T540D337M003CH8605 is a type of Tantalum-Polymer capacitor designed to be used in mobile telecommunication systems due to its highly stable base capacitance and very low ESR characteristics. It is suitable for both high voltage and high temperature applications, as well as for high temperature operating conditions and general capacitor applications.

Application Field

T540D337M003CH8605 is primarily used in the mobile telecommunication sector, including the 4G/5G and LTE networks. Given its high capacitance, low ESR, and low voltage dielectric absorption characteristics, the capacitor is well suited for power amplifier and RF power amplifier applications where the performance of the circuit is paramount.

Other uses include resonant oscillator circuits, pulse circuits, RF tuners and filters, as well as clocking and tuning of radio frequency ICs such as PLL and LNB. It is also suitable for use in portable and stationary battery-powered devices where its low ESR, high capacitance and competitive price offer an attractive cost-benefit ratio.

Working Principle

T540D337M003CH8605 operates as a low-ESR, high-capacitance device, as a result of its internal construction. The capacitor is made up of layers of tantalum pentoxide, a semi-conductive material, sandwiched between layers of polymer, giving it a total capacitance of 337 μF and ESR of 0.003Ω. This construction gives the capacitor excellent stability over time and temperature, and also allows it to be used in high-voltage applications.

The capacitor is designed to be connected in series/parallel and has a voltage rating of 16V. Its self-healing function enables it to withstand and recover from shocks, as well as to self-repair any micro-short circuits that might occur in the construction. This helps ensure a high level of reliability and a longer lifespan for the capacitor.
