It is also used in audio systems, such as power amplifiers and loudspeakers, where it plays an important role in preventing electrical noise.

Working Principle

The TPME228M002R0018 is a polarized capacitor and is therefore connected with its anode and cathode terminal in a specific direction. The terminal/lead with the longer length is connected to the anode, while the terminal/lead with the shorter length is connected to the cathode. This is important for the capacitor to function correctly.

The TPME228M002R0018 capacitor uses the principle of electrostatic charge storage. This capacitor consists of two metal plates separated by an insulating material called the dielectric. As a voltage is applied across the plate, the electrostatic charge accumulates on each plate, forming an electric field. The electric field stores the energy, which can be released in the form of electrical current.

The capacitance of the TPME228M002R0018 is determined by the size of the plates, the thickness of the dielectric, and the material used in the construction of the capacitor. The ESR, or equivalent series resistance, is a measure of the resistance to current flow through the capacitor. The lower the ESR, the better the capacitor performs.

The TPME228M002R0018 is designed to provide high ripple current, which is essential for high performance electronics. The ripple current is the alternating current that passes through the capacitor and is important for the maintenance of electrical efficiency. The capacitor is also designed to withstand extreme temperature changes, from as low as -55°C to as high as +125°C, making it suitable for a wide range of applications.

Conclusion

The TPME228M002R0018 is a 2.2 µF capacitor with a low ESR and high ripple current. It is suitable for a wide range of applications, such as automotive, medical, energy storage, power quality, audio systems, high current pulses and switching applications. The capacitor works on the principle of electrostatic charge storage and utilizes two metal plates and a dielectric material to store energy, which can be released as electrical current. The capacitance, ESR and ripple current are key parameters of the capacitor and are determined by the size of the plates, the thickness of the dielectric and the materials used in construction of the capacitor.
