Power Line Filter Modules are designed to meet the needs of network equipment, power supplies, and motors, providing noise filtration solutions that reduce or eliminate the EMI or RFI levels in electrical circuitry. FN409-13-02 is one of such modules and it can be applied in different fields. In this article, we will discuss the application field and working principle of FN409-13-02.

FN409-13-02 is applicable for motor drives in a broad range of industries, including instrumentation, automation, induction cooking, testing, and precision control systems. It can also be used to suppress various types of high-frequency electric noise in the power supply lines. It is suitable for the protection of power lines from transients resulting from arcing, short circuits, and lightning surges.

The working principle of FN409-13-02 can be explained succinctly. It is built with segmented line filter technology and designed to reduce high frequency noise generated by high-power applications. The line filter generally consists of three stages: two capacitive stages between the line and AC lines, and one inductive stage between Lines A and B. The two capacitive stages can be of different capacity to provide the necessary protection to the power supply line, while the inductive stage is used to block and divert high frequency noise.

FN409-13-02 has three distinct advantages compared to traditional filters. First, its power loss is less than 1/3 of the traditional filters\', making it economical. Second, its EMI filtering efficiency is better, the line filter can achieve up to 80dB attenuation in the 200 KHz to 30MHz frequency band, and up to 50dB attenuation in the 66 MHz to 1GHz frequency band, effectively cutting off the interference. Third, it has a long lifespan, rated up to 50,000 hours.

In summary, FN409-13-02 is a reliable power line filter module, with excellent attenuation performance and long service life, which can be widely used in motors, power systems, and other high-power applications. It is an excellent choice for those who need noise filtration solutions for protecting their circuitry and equipment.
