FN258-30-33

Power Line Filter Modules are frequency dependent circuit components used for a variety of applications such as signal interference, noise suppression, signal filtering, and filtering of harmonics. The FN258-30-33 model offers outstanding performance in an ultra-compact size, making it a perfect candidate for applications where space is limited. It is ideal for applications where large currents must be handled but size and weight are a concern. The FN258-30-33 is a high-efficiency power-line filter module that combines low-pass, high-pass and differential-mode (DM) filtering elements into a single compact package. It is designed to reduce EMI (electromagnetic interference) and other unwanted noise in power systems.

The FN258-30-33 filter module utilizes an array of metal-oxide varistors (MOVs) and inductors connected in parallel to form a wide-band low-pass filter. This provides high-frequency suppression of up to 15MHz and covers the entire range of common-mode (CM) frequencies. The module also contains an isolated high-pass filter, which provides high-frequency suppression up to 70MHz. The combination of these two filter types allows for effective control of all types of EMI within the specified frequency range. The module also includes a differential-mode filter to reduce noise between the power leads. The module uses a combination of ferrite beads, capacitors, and a metal-oxide varistor to provide robust filtering of common-mode and differential-mode noise.

The FN258-30-33 module is rated for a power rating of 30A and an operating voltage range of 12-48Vdc. The module has an insertion loss of up to 70dB at 40MHz and provides up to 82 dB of common-mode attenuation at a working frequency of 30MHz. The module is designed to meet the requirements of UL60950 and is RoHS compliant. The module has a system PEC slot that can be used for the addition of external capacitors for further noise external circuit noise suppression. The device also features side-mounted LED indicators for power and fault warnings.

The FN258-30-33 is a compact, high-efficiency power-line filter module that combines wide-band low-pass, high-pass and differential-mode filtering elements into one package. With its high-frequency suppression capabilities, robust filtering of common-mode and differential-mode noise, along with its LED indicators for power and fault warnings, the FN258-30-33 module is an ideal choice for applications where space is limited and power needs to be handled efficiently.
