Tantalum capacitors are electrochemical components used for storing energy. The 135D127X9008F2 is a type of tantalum capacitor. This capacitor has several application fields and its working principle should be understood to properly use it.

Application fields

The 135D127X9008F2 is a low-profile, molded-in-place, sealing-style tantalum capacitor. It is ideal for use in dense, complex, multi-layer circuit board designs, as it has a smaller form factor and case height than other capacitors. It is reliable in high-temperature applications, and is especially suitable for medical, aerospace, and off-road vehicle applications, as well as other products requiring hermetic-level sealing and a compact design.

The 135D127X9008F2 has a wide range of electrical characteristics, including a small ESR of 2.4 ohms, maximum voltage of 10 volts, and capacitance up to 450 μF. This makes it suitable for use in applications such as decoupling circuits, power supply filtering, audio/video channel noise removal, and voltage-regulator bypass circuits.

The 135D127X9008F2 is also suitable for commercial applications such as personal electronics, smart phones, power supplies, and automotive applications. It is generally preferred in commercial applications due to its small size, low equivalent series resistance (ESR), and low cost.

Working principle

Tantalum capacitors are electrochemical components that use the electrolyte-to-electrode contact area as the main capacitance carrier, instead of the conductive material used in traditional capacitors. This allows for more efficient energy storage than traditional capacitors.In a 135D127X9008F2 capacitor, the anode is a tantalum powder pressed into a cylindrical pellet and coated with a protective coating. The cathode is formed by a dielectric layer, typically bonded to the pellet using a solvent-resistant epoxy. The anode and cathode are then separated and sealed in the molded case.When a voltage is applied to the capacitor, the electrons on the anode are attracted to the cathode, creating a flow of electrical current. This is the same principle by which other capacitors work. However, in the 135D127X9008F2, the high contact area between the electrolyte and the electrodes allows for more efficient energy storage.In addition, the 135D127X9008F2 is highly reliable and resistant to temperature changes, which makes it suitable for use in a wide range of applications.

Conclusion

The 135D127X9008F2 is a type of tantalum capacitor with a wide range of application fields, including medical, aerospace, and off-road vehicle applications. It has a small ESR of 2.4 ohms, maximum voltage of 10 volts, and capacitance up to 450 μF. The working principle of this capacitor is based on the traditional capacitance principle, but with an increased contact area that provides efficient energy storage.
