Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor. They are widely used in a multitude of applications, due to their high volumetric efficiency and relatively long life. The most common type is the M39003/09-3010/HSD type, which has many different applications and working principles.

M39003/09-3010/HSD Application Fields and Working Principle

M39003/09-3010/HSD capacitors use non-polarized tantalum powder and a solid electrolyte instead of two liquid electrodes. The powder is compressed into a pellet shape and then coated with a solid electrolyte, creating two different regions of charge. A thin oxide film insulation layer is then formed on the bottom of the pellet to improve PC board retention. Depending on the requirement, the M39003/09-3010/HSD type is specified for low-impedance requirements, high-voltage requirements, and small dielectric absorption properties.

The M39003/09-3010/HSD accepts higher current loads and has excellent capacitance stability performance over a wide temperature range. The device has a long life time with a shelf life of up to 210 hours at 125 °C. The capacitance stability of the M39003/09-3010/HSD is superior to other types of tantalum capacitors, and the working voltage range can be as high as 10V. The capacitors also have high reliability due to low leakage and low ESR.

M39003/09-3010/HSD capacitors are commonly used in low ESR, high ripple current, and long life requirements. An example of these applications includes general decoupling and filtering for applications that require energy storage, such as in power supply design. These capacitors are also used in a wide range of precision instrumentation and medical equipment designs, since their superior performance is able to reduce EMI/RFI noise.

Additionally, the M39003/09-3010/HSD capacitors are used in temperature sensing and signal processing applications. The device offers extended performance in comparison with other capacitors, and is able to monitor temperature and control devices using temperature feedback, as well as provide accuracy and precision measurements in microcontroller-based applications.

The working principle of M39003/09-3010/HSD capacitor is based on Faraday’s Law of Electrolysis, where the electrical energy is converted into chemical energy, which is then stored in the capacitor. As the charge accumulates within the dielectric layer, an electric field is created between the two extremities of the conductors. This field causes a voltage difference and electricity is flowing from the positive conductor to the negative, which then creates a capacitance.

In conclusion, M39003/09-3010/HSD capacitors are a type of electrolytic tantalum capacitor which offer high performance and reliability. They are commonly used in power supply design, instrumentation, medical equipment, temperature sensing, and signal processing applications. The working principle of the M39003/09-3010/HSD is based on Faraday’s Law of Electrolysis, where electrical energy is converted into chemical energy and stored in the capacitor.
