Power line filter modules are used in equipment to prevent unwanted signals and interference from entering or leaving the unit, while allowing wanted signals to pass through with negligible or minimal attenuation. These modules, especially the FN354-12-05, form an integral part of design in order to improve signal integrity, reduce EMI and ensure overall performance of the components.

Application Field Of FN354-12-05 Filter Module

The FN354-12-05 filter module is widely used in various systems, related to electrical production, electronics, communication, electronics industry, power supplies, and aviation. The application field mainly includes:

• Domestic appliances.
• Industry robotics automations.
• Industrial machines and equipments.
• Power electronics for electric vehicles.
• Telecommunication equipments.
• Electronic lighting equipment.
• Military and defense systems.

The FN354-12-05 power line filter module is a high-grade filter designed to meet the requirements of high-performance industrial-grade applications. This module is constructed with two filter elements with the outer case being made from die-cast aluminum. This provides efficient cooling and excellent protection against vibration and shock.

Working Principle Of FN354-12-05 Filter Module

The FN354-12-05 power line filter module utilizes a combination of common mode and differential mode filtering in order to provide a high level of emi/rfi rejection. The filter is designed to provide a low insertion loss and a high isolation level between the input and output over the frequency range of 10Hz to 3MHz. This low frequency range is especially useful for compensating for high frequency noise components.

In this filter module, the common mode choke performs both impedance matching and attenuation of high frequency couples or harmonic signals. This also helps reduce or eliminate interference or noise that may occur in sensitive circuits. On the other hand, the differential mode filter works to reduce the amplitude of high frequencies that may cause interference in sensitive components. The effective impedance of the filter in this mode also determines the level of attenuation.

The FN354-12-05 filter module also includes surge protection, which is designed to protect the circuit against transient voltage spikes that can occur due to lightning or other causes. The surge protection is provided by a varistor which is designed to clamp the voltage to a defined level. The surge protection in this module operates over a range of 5-30V with a maximum rating of 400V.

Overall, the FN354-12-05 power line filter module offers a wide range of features and benefits, making it an ideal choice for a wide variety of applications. These include improved signal integrity, reduced EMI emissions, protection against surges, and an overall improved performance of the equipment in which it is installed.
