Tantalum – Polymer Capacitors

Tantalum – Polymer capacitors are used in a variety of different applications and provide reliable energy storage solutions. The T540D226M020BH8505 device is one of the most popular items in this category and is widely used in consumer and industrial applications. In this article, we will discuss the application field and working principle of the T540D226M020BH8505.

Application Field of the T540D226M020BH8505

The T540D226M020BH8505 is a surface-mount tantalum capacitor that is primarily used for filtering power supply circuits, both on consumer products such as cell phones and computers, and in industrial applications. This device also can be used in voltage regulator circuits, as well as any other applications that require high stability and low noise.

Due to their reliability, these capacitors are also used in harsh environments, such as the automotive and aerospace industries, or in medical devices or military applications. Their low profile – the device is just 0.40mm tall – allows them to be used in components with very tight critical dimensions, such as motherboards.

Working Principle of the T540D226M020BH8505

The T540D226M020BH8505 is basically a pair of opposing electrodes (the cathode and the anode) with a dielectric material (the electrolyte) in between. The structure is made of tantalum and polymer, and this combination gives it a high capacity and high stability.

When a voltage is applied, a tiny amount of current is released onto the electrolyte, which results in the formation of a conductive pathway between the two electrodes. This process is called polarization, and it increases the capacitance of the device, allowing it to store more energy than a typical capacitor. The device is polarized at a certain voltage, meaning that if you apply voltages higher than the rated voltage, the device will become unreliable and short out.

The T540D226M020BH8505 is a low-leakage device, meaning that the leakage current is much lower than that of other capacitor types. This makes it ideal for applications requiring less capacitance but higher reliability, such as power supply filtering.

Conclusion

The T540D226M020BH8505 is a high-quality, reliable surface-mount tantalum capacitor. It can be used in a variety of applications, ranging from consumer to industrial, and it has a low profile making it ideal for components with tight critical dimensions. It is also very reliable, due to its low-leakage nature and high capacitance stability.
