Tantalum capacitors are commonly used electronic components in the consumer electronics and industrial control applications. The M39003/01-2851H is a tantalum capacitor designed specifically for these applications, and has a range of features that make it well-suited to them. This article will explain the application field and the working principle of the M39003/01-2851H.

M39003/01-2851H Application Field

The M39003/01-2851H is a non-polarized tantalum capacitor with an anode composed of a metal manganese dioxide material and a cathode composed of a hydrogen-filled tantalum powder. This design is suitable for both high-temperature and low-temperature applications, making it a good fit for consumer electronics and industrial control. The capacitor offers low-noise operation, low-ripple performance, and can withstand high surge currents with minimal effect on performance. It is also designed for minimal power consumption, which makes it perfect for battery-operated applications.

The M39003/01-2851H is available in a variety of sizes, including 1.0 μF, 1.5 μF, 3.3 μF, and 6.3 μF. The 1.0 μF and 1.5 μF sizes are ideal for high-frequency decoupling, while the higher-capacitance 3.3 μF and 6.3 μF sizes are better suited for high-voltage applications.

M39003/01-2851H Working Principle

The M39003/01-2851H is a non-polarized tantalum capacitor, which means that the capacitor is not polarity-sensitive. This means that the device is not affected by inverse voltages, and the same technology can work without regard to the device’s orientation. As such, it can be used in any direction without changing the performance.

The capacitor’s working principle relies on the changing resistance of the tantalum powder when it is subject to direct power from a signal or voltage. The powder undergoes an electrochemical reaction and gradually loses its ability to store charge, which is why the tantalum capacitor has a finite lifetime. If the capacitor is overcharged, it will eventually fail to store charges and needs to be replaced.

The M39003/01-2851H’s anode is composed of manganese dioxide and is used to absorb and store the signal current of the capacitor. The cathode, made of tantalum powder, is used to release the stored current. Because of the non-polar design, the capacitor has good insulating properties and has a low risk of short circuits and other risks that can be associated with polarized capacitors.

The capacitor’s dielectric material is composed of an electrolyte which is a liquid that can store charge. This material has high capacitance and low ESR, making it well-suited to the applications in which it can be used. The dielectric material is designed to be temperature-stable over a wide temperature range.

Conclusion

The M39003/01-2851H is a high-performance tantalum capacitor which is suitable for consumer electronics and industrial control applications. Its low-noise operation, low-ripple performance, and Power-saving design make it perfect for battery-powered applications. The M39003/01-2851H’s working principle relies on the changing resistance of the tantalum powder when it is subject to direct power from a signal or voltage, and its dielectric material has high capacitance and low ESR.
