Feed Through Capacitors

Feed through capacitors are an indispensable tool in various electronic circuits and systems. They allow electrical energy to be stored at one end of a circuit while the other end is used to draw energy from. The PSM4-680M-15T2 is a type of feed through capacitor specifically designed to meet the needs of certain applications. This article will discuss the application field and working principle of this particular device.

Application Field

The PSM4-680M-15T2 feed through capacitor is designed to be used in applications that involve the transfer of power and signals between two points. This type of capacitor is ideal for use where an electric current is required to be transferred from a source point to a destination point with minimal interference. Some applications include the following:

• Wireless communication systems
• Low-frequency high-speed switching networks
• High-frequency power amplifiers
• High-frequency power converters
• Digital signal processors
• Signal flow control circuits
• Surge suppressors
• Data acquisition and control systems

The PSM4-680M-15T2 feed through capacitor is tailor-made for applications where power and signal transfer must be conducted with minimal levels of signal interference and noise. It is also suitable for applications where either an AC or DC voltage needs to be passed through it. This is particularly advantageous in applications such as wireless communication, where an AC voltage is required.

Working Principle

The PSM4-680M-15T2 feed through capacitor works by storing electrical energy at one end of the circuit and then releasing it at the other end. The capacitor is designed with a specially formed casing that allows for the minimization of EMI (electromagnetic interference). In fact, the capacitance is many times greater than that of the same size of conventional capacitors, which is a key factor in reducing EMI levels. The capacitor is also designed with an internal resonant circuit that helps reduce the effects of high-frequency noise. This resonant circuit consists of a combination of inductors and capacitors which help to filter out any unwanted noise or interference. By using this circuit, the PSM4-680M-15T2 feed through capacitor can reduce the amount of EMI dramatically.The PSM4-680M-15T2 feed through capacitor also has a frequency response range of up to 500MHz, which means it is suitable for operations at high frequencies. This is beneficial for applications such as switching networks, digital signal processors and wireless communication where high frequency signals are often required.

Conclusion

The PSM4-680M-15T2 feed through capacitor is an ideal device for applications that require the transfer of power and signals between two points with minimal levels of interference. Its special casing design and internal resonant circuit reduce EMI levels significantly while its frequency response range up to 500MHz makes it suitable for use in high frequency operations. Thus, the PSM4-680M-15T2 is a practical and efficient feed through capacitor for modern electronic applications.
