HAIPART's Sendust magnetic core (μi=125), designed specifically for RCBOs, achieves an impedance of ≥2kΩ in the 10kHz-100MHz frequency band and passes IEC 61000-4-5 testing. Its multi-layer nanocrystalline ribbon stacking structure achieves insertion loss of -45dB at 30MHz, effectively suppressing common-mode interference in 1P/2P 30mA leakage protection circuits while maintaining a temperature rise of ≤25K at a rated current of 40A.
Applications
Suitable for smart home systems, new energy power, Industry 4.0, and other fields.
FAQ
Q1:What is the main function of a magnetic core?
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.
Q9:What after-sales services do you provide?
A9:We provide comprehensive after-sales services, including product consultation, technical guidance, installation and commissioning, repair and replacement, and warranty.
Q10:How can I contact your technical support?
A10:Technical support can be contacted through the official website, customer service hotline, or email.
