EMI/RFI Filters (LC, RC Networks) can be used to protect against a wide range of interference, and the PSM1-102M-10B EMI/RFI filter is no different. This filter is characterized by an exceptionally low insertion loss of up to 1.5 dB and a high rejection of up to 90 dB, making it a great choice for applications in which noise suppression is especially important.

The PSM1-102M-10B is a surface mount filter designed for use in the frequency range of 9 kHz - 2.5 GHz, making it suitable for many radio frequency (RF) and electromagnetic interference (EMI) applications. It features an L-C filter design, in which the inductor and capacitor components are used to make a simple low-pass filter. This type of filter is commonly used in applications that require minimal-to-moderate levels of signal attenuation, and the particular advantage of the PSM1-102M-10B is that it allows for significantly more attenuation than a typical resistor-capacitor (RC) filter.

Because of its low insertion loss and high rejection, the PSM1-102M-10B is particularly well-suited for use in applications such as medical imaging systems, radar systems, communication systems, and other high-frequency applications. In addition, it can be used to eliminate high-frequency noise in circuits that utilize voltage regulators, charge pumps, and other power management devices.

The PSM1-102M-10B filter works by attenuating or blocking high-energy radio frequency and electromagnetic interference, allowing only low-energy signals to pass through. This filtering is achieved through the use of lumped inductors and capacitors, which are tuned to different frequencies to create a band-pass filter. For example, an inductor-capacitor combination tuned to the frequency of a interference source can be used to reduce the amount of energy emitted from the source, while an inductor-capacitor combination tuned to the frequency of a desired signal path can be used to allow the signal to pass through.

The filter also contains several internal components that allow it to function effectively, such as an internal neutralizing capacitor, which reduces the influence of oscillations on the filter performance. In addition, the filter includes a bonding pad, to which ground planes can be attached in order to further reduce the level of EMI/RFI interference. Finally, the filter also includes a low-inductance pass-through contact, which serves to dissipate any residual EMI/RFI interference.

In summary, the PSM1-102M-10B EMI/RFI filter is a well-designed, high-performance filter that is well-suited for a variety of applications, especially those in which noise suppression is particularly important. With its low insertion loss and high rejection capabilities, the filter is able to effectively reduce the level of EMI/RFI interference, allowing only low-energy signals to pass through. It is also able to effectively dissipate any residual interference, ensuring that the signals that are passed through remain clean and distortion-free.
