Power line filter modules are common in modern electronic circuits. They can attenuate conducted electric noise from the power line to the ground, attenuating and suppressing electromagnetic interference (EMI) while preventing damaging spikes and overvoltage components from entering the system.

The FN258HV-130-35 is a power line filter module designed for use in a variety of applications, ranging from consumer electronics, industrial and medical equipment to telecommunications systems. The module offers high-frequency noise suppression up to 35 dB across its operating range of 150 kHz to 1.6 GHz. Furthermore, the module provides a high level of protection to help prevent system damages from overvoltage power surges.

The FN258HV-130-35 includes two filter capacitors and two common-mode inductors providing a two-stage filter network. The two stage approach provides an effective solution to filter conducted EMI noise from both the power and the ground. The capacitor located at the input side of the filter helps attenuate common mode conducted noise on power cord. The inductor and the capacitor at the output side of the filter provides attenuation for the differential mode conducted noise.

The FN 258HV-130-35 filter modules are suitable for a variety of applications and are widely used in medical, industrial, consumer electronics, and telecommunications applications. They can be used to effectively reduce EMI noise for high-speed bus systems, such as USB and Ethernet, thus ensuring reliable operation of sensitive electronic systems.

The FN258HV-130-35 filter also provides an effective ground path for the sensitive electronic systems which are susceptible to external electromagnetic fields. It helps reduce the amount of EMI entering the overall system, thus ensuring optimal performance.

In summary, the FN258HV-130-35 power line filter modules are ideal for a variety of application where conducted EMI noise is a concern. They offer high-frequency noise suppression up to 35 dB across its operating range of 150 kHz to 1.6 GHz and help protect systems from overvoltages. Furthermore, they provide an effective ground path for the sensitive electronic systems, helping to reduce the amount of EMI entering the overall system and ensuring optimal system performance.
