HAIPART Magnetic Cores: High-Efficiency EMI Suppression, Safeguarding Electrical System Stability
As a leading magnetic core manufacturer in China, HAIPART's magnetic cores are made from high-purity ferrite materials using a precision sintering process. They possess high permeability, low coercivity, and low loss characteristics, attenuating over 90% of interference signals in the 10-100MHz high-frequency range while maintaining stable magnetic performance. They are corrosion-resistant, have high mechanical strength, and are suitable for harsh industrial environments. Employing a ring-shaped structure design with precisely calculated inner and outer diameters, they perfectly match the circuit breaker conductors or housing, forming a closed magnetic circuit, improving utilization efficiency and enhancing EMI suppression uniformity. The FT-12A magnetic core is specifically designed for miniature circuit breakers (MCBs), with a compact size for easy embedding; the FT-50G magnetic core is suitable for molded case circuit breakers (MCCBs) and can handle larger currents and higher power EMI interference. Widely used in various circuit breakers and electrical systems, HAIPART provides customized EMI solutions for different scenarios.
A1:Suppressing high-frequency electromagnetic interference (EMI) improves the electromagnetic compatibility (EMC) of wire systems by converting high-frequency noise into heat energy dissipation.
Q2:What is the working principle of a magnetic core?
A2:At low frequencies, the impedance is low, while at high frequencies, the impedance increases sharply, forming a "reflection-absorption" mechanism for noise.
Q3:How to choose magnetic core materials?
A3:Select impedance matching materials based on the interference frequency; for high-frequency noise, nickel-zinc ferrite is preferred.
Q4:How to match the core size?
A4:The inner diameter needs to be compatible with the outer diameter of the wire. The longer the length, the better the filtering effect, but the installation space needs to be considered.
Q5:What are the requirements for the installation location of the magnetic core?
A5:Stay close to the source of interference and avoid being far from the noise emission point.
Q6:How does the number of turns in the magnetic core winding affect the performance?
A6:For low-frequency interference, it is recommended to use 2-3 turns to increase the equivalent absorption length, while for high-frequency interference, use a single turn or half turn to avoid the impact of distributed capacitance on performance.
Q7:What are the common causes of magnetic core failure?
A7:Material aging, improper installation.
Q8:What are the prices of your products?
A8:Product prices vary depending on the model, specifications, and quantity. Please consult the sales team or check the official website for details.
