The PSM4-821M-05B is a feed through capacitor that has a number of applications in various industries. It is a low-pass filtering capacitor that is used to reduce or eliminate high frequency noise in power and signal lines of electronic circuits. It is an ideal device for power quality improvement, EMI/RFI filtering and interference/noise suppression.

The feed through capacitor is constructed with a base material of PTFE for excellent dielectric characteristics. The ceramic disc is embedded into the PTFE housing and the disc material is chosen to provide higher Q values which enables higher attenuation, while maintaining low dissipation factor, low capacitance data and consistent performance. Capacitance values range up to 20 microfarads.

One of the key features of the feed-through capacitor is its very low ESR or Equivalent Series Resistance. This allows greater current flow and lower dissipation losses in circuits. The high energy density of the feed through capacitor also allows for better electrical energy transformation and dissipation.

The feed through capacitor can be used in many different applications such as radio frequency interference and frequency dependent RF attenuation, AC line bypass filters, high frequency power converters and AC-DC motor drives. It is also widely used in industrial and commercial electronics, medical imaging systems, test instrumentation, UPS systems, telecom systems, audio and video equipment, automotive audio systems and car audio systems.

The working principle of the feed through capacitor is quite simple. It consists of two plates, one of which is connected to the input end while the other is connected to the output end. The capacitor acts as a low-pass filter by allowing low frequency signals to pass through while blocking high frequency signals. The capacitance of the capacitor is very important as it determines the bandwidth of the filter and determines the amount of noise that can be allowed through. The capacitor also provides a certain amount of energy storage which can be used by the circuit. The amount of energy stored depends on the capacitance of the capacitor.

In conclusion, the PSM4-821M-05B feed through capacitor is an essential device in many industries and can be used in a variety of applications. Its low ESR, high energy density and highly tuneable capacitance values make it an ideal device for power quality improvement, EMI/RFI filtering and interference/noise suppression. As a result, it is widely used in many different applications including radio frequency interference, AC line filters and motor drives.
