Tantalum - Polymer Capacitors

Tantalum - Polymer capacitors are increasingly used in many different applications due to their reliability and low cost. The 10TPB47M capacitor is a popular choice due to its low ESR, wide temperature range, and potential for longer life. This capacitor works on the principle of charge storage, where a dielectric material separates the two terminals and charges are stored between them.

What is a 10TPB47M?

The 10TPB4747M capacitor is a surface mount tantalum-polymer capacitor. The capacitor is available in two main versions, the standard 10TPB47M or the non-polar 10TPB47MN. This type of capacitor is generally used for high-density intermittent or pulsed load applications such as personal electronics, notebook computers and cell phones. The capacitor has excellent mechanical stability and low profiles. The dielectric layers of the 10TPB47M are based on a thermally conductive polyethylene film with a tantalum polymer anode and a conductive anode consisting of quasi-solid electrolyte.

Application Fields

The 10TPB47M is suitable for a variety of applications due to its low ESR, wide temperature range, and potential for longer life. These include automotive, industrial, consumer electronics, medical, telecommunications, instrumentation, military, and space. For example, in automotive applications the 10TPB47M capacitor is used to filter out interference and to provide alternative current sources in the event of a failure in the main power supply. In consumer electronics, the 10TPB47M capacitor is used for power smoothing and to reduce EMI (electromagnetic interference). In medical applications, the capacitor is used to power small medical devices such as infusion and dialysis pumps, and in the telecommunications industry, they are used to filter interference in long-haul optical and copper-based communications. The 10TPB47M is popular in the instrumentation industry as well, as it is able to withstand large voltage pulses and fluctuations.

Working Principle

The 10TPB47M uses a high dielectric constant material such as tantalum pentoxide (Ta2O5) as a dielectric layer between the two terminals. The current passes through the capacitor, creating an electric field through the dielectric material. This field produces a separation of the negative and positive charges, and the resulting potential difference across the terminals produces an electric current when a voltage is applied. This charge storage capability is known as capacitance. The capacitance of the 10TPB47M is determined by its size and shape as well as its dielectric constant.

Conclusion

The 10TPB47M is a popular capacitor due to its low ESR, wide temperature range, and potential for longer life. It is used in a wide array of applications, from automotive to medical, due to its versatility and reliable performance. The capacitor works on the principle of charge storage, where a dielectric material separates the two terminals and charges are stored between them. The 10TPB47M is a great choice for any application, from filtering out interference to providing alternative current sources.
