Tantalum – polymer capacitors are an innovative class of capacitors that has been gaining popularity due to its advantages over other competing technologies.ETPU100MSI is a type of tantalum – polymer capacitor and is a popular choice when it comes to general purpose and precision applications. This article explores the application field and working principle of ETPU100MSI.

Application Field

Tantalum – polymer capacitors are suitable for use in a wide variety of applications including signal coupling, storage, DC blocking, and timing. In addition, they offer superior performance in a variety of demanding environments, such as high temperatures, high-frequency, and low-impedance. ETPU100MSI, in particular, is designed for general-purpose applications, precision applications, and high-temperature applications–up to 100 degrees Celsius. It can also withstand up to 5V of reverse voltage.

Due to its low ESR values, ETPU100MSI can also be used for pulse applications and power conditioning. The ETPU100MSI is especially suitable for high-density, low-impedance circuits, such as circuit boards and embedded devices. It is also very popular in applications that require power backup, such as servers and mobile phone batteries. In addition, ETPU100MSI is well-suited for applications that require temperature stabilization, such as lighting, temperature controls, and robotic systems.

Working Principle

ETPU100MSI is based on the principle of a “solid electrolyte” capacitor. This type of capacitor consists of two plates separated by a solid electrolyte. When a voltage is applied to the plates, a charge is created and stored in the capacitor. This charge can then be released upon demand to create the desired power surge.

The solid electrolyte used in ETPU100MSI (tantalum pentoxide) is a highly conducting, low-temperature polymer that allows for high capacitance values in minimal space. This makes ETPU100MSI valuable for high-density and low-impedance designs. The polymer also provides superior capacitor performance in a wide variety of ambient conditions from extremely low temperatures to extreme high temperatures.

The electrolyte in ETPU100MSI is surrounded by electrodes that are made of small particles, called electrolyte particles. These particles are made of either nickel or copper-aluminum granules, depending on the specific application. The particles provide a greater surface area for the electrolytic solution to act upon and maximize the capacitance per unit volume. This is what allows ETPU100MSI to function with a significantly reduced external voltage.

Benefits

Tantalum-polymer capacitors offer a number of significant benefits compared to traditional electrolytic capacitors. Firstly, they have a much higher capacitance-to-volume ratio than traditional technologies and require minimal space for installation. This makes them valuable for applications that require high-density or low-impedance circuitry. Secondly, since the electrolyte is a solid, the capacitor is unaffected by vibration or shock, making them suitable for life-critical applications. Thirdly, they have excellent temperature and frequency response, making them suitable for high-temperature and high-frequency applications. Finally, they are very stable and reliable, with a long and robust lifespan.

ETPU100MSI tantalum – polymer capacitors offer all of these benefits and can provide reliable performance in a wide variety of applications. The combination of its solid electrolyte, low ESR values, high capacitance, and temperature stability make ETPU100MSI an excellent choice for the most demanding precision and high-temperature applications.
