The filter circuit is a two-pole X common mode Y differential mode filter power supply, which can effectively suppress and eliminate the interference components of the AC circuit. When used with a decoder, the sound is soft, the resolution is improved obviously, and the background is clean;
This filter board is all made of high-quality components, including brand new flat copper common mode inductors, professional X2, Y2 filter capacitors, and military-regulated FR4 PCB boards;
This EMI filter board is used to purify the city power. During use, the components on the board may have high voltage from the city power. Please be careful not to touch the circuit board and its components at will to avoid electric shock!
Suitable for headphone amplifiers, pre-amplifiers, DAC decoders, etc.
PCB is silver-plated process, lower internal resistance, better conductivity
Common mode inductance
Large current, small size, low DC resistance, good EMI effect, very small distributed capacitance,
High insulation strength, which can extend the life of electrical appliances.
The high-frequency skin effect is good, and the unit current density is higher than that of round copper wire.
It adopts automatic machine winding, single-layer winding, no crossover and overlap, and good heat dissipation effect.
Closed magnetic circuit design, small magnetic leakage, good impedance balance and good conduction and radiation effect, and stable consistency.
Professional imported HIFI filter capacitors, the effect is better than ordinary capacitors, high-frequency internal resistance is low.
