The Common Mode Choke Core from Beijing Bidragon Machinery Co., Ltd. is designed for use in high-frequency switching applications such as inverters, UPS systems, and solar energy converters. It is engineered to suppress electromagnetic interference by presenting high impedance to common mode noise while allowing differential signals to pass unaffected. The core material exhibits high saturation magnetic induction intensity, enabling compact inductor designs without compromising performance under heavy load conditions.
These cores are typically manufactured from ferrite compositions with optimized temperature stability and low core loss across a broad frequency range. Industry-standard operating temperatures extend from -40°C to +125°C, with impedance characteristics calibrated for frequencies between 1 MHz and 100 MHz. The design resists unbalanced current drift, a critical trait in applications with fluctuating DC bias such as renewable energy inverters. Material composition aligns with MnZn ferrite standards common in industrial EMC filtering.
Buyers in the renewable energy, industrial power supply, and automotive electronics sectors commonly specify these cores for EMI reduction in switch-mode power circuits. They are supplied in bulk quantities, typically packed in anti-static tubes or trays for automated assembly. Trade terms are negotiable based on volume, with standard packaging designed for long-term storage in ambient conditions. Lead time and minimum order quantities require direct confirmation with the supplier.
| Core Material | MnZn ferrite, typical for high-permeability common mode chokes |
| Saturation Flux Density | High saturation magnetic induction intensity, typical range 400 mT to 500 mT |
| Operating Temperature Range | -40°C to +125°C, standard for industrial-grade EMC components |
| Frequency Range | 1 MHz to 100 MHz, typical impedance peak range for common mode filtering |
| Impedance Characteristic | High common mode impedance with low differential mode insertion loss, standard in power supply filters |
| Core Shape | Toroidal or E-core, typical for high-efficiency winding configurations |
| Temperature Coefficient | Low temperature drift, typical ±100 ppm/°C for stable performance |
| Insulation Class | Class B (130°C), standard for resin-coated magnetic cores |
| Packaging | Bulk in anti-static tubes or trays, typical for SMT and automated assembly |
| Weight per Unit | Varies by size, typical range 0.5 g to 5 g depending on core volume |
Beijing Bidragon Machinery Co., Ltd. is a manufacturer based in Beijing, China, with a registered address in the South-West Third Ring Road area. The company is listed with harbor-tier verification, indicating basic business legitimacy but no third-party audit or certification disclosures. The listing shows no response rate or average response time, suggesting limited buyer engagement or communication infrastructure.
The supplier specializes in magnetic components for power electronics, with product focus on common mode choke cores and related inductors. No information is provided about production capacity, workforce size, export history, or client references. The absence of certifications, quality control documentation, or testing reports means buyers must request independent verification of material properties and performance claims.

Sourcing Common Mode Choke Core from Beijing Bidragon Machinery Co., Ltd. - China Import Guide
Before placing an order, verify the core material composition and saturation characteristics with test reports from the supplier. Confirm that the ferrite grade matches your circuit’s frequency and bias requirements. Request a sample batch for in-house impedance and temperature testing under real operating conditions to validate performance claims.
Lead time is not stated in the listing and must be confirmed directly. Standard trade terms are likely FOB China port, but Incoterms, payment methods (T/T, LC), and packaging options (bulk, reels, trays) vary. Clarify whether the supplier handles export documentation and if they provide commercial invoices and packing lists compliant with your country’s import regulations.
For quality assurance, require a certificate of conformity and dimensional inspection reports for each batch. Check for consistent core color, absence of cracks, and uniform surface finish. Perform inductance and Q-factor measurements on received samples. Retain a sample from each shipment for future reference in case of field failures.
