Yu Yang Magnetic Co., LTD. (YET) is a professional common mode choke manufacturer, offering high-performance solutions for EMI filtering in power electronics, automotive, telecom, industrial control, and renewable energy systems. With full in-house capabilities in core processing, winding, and vacuum encapsulation, we supply both custom inductors, such as custom and standard common mode chokes designed to meet your exact application requirements.
Custom Design Support: From SMD to through-hole, toroidal to UU-type structures, we deliver custom common mode chokes tailored for EMI suppression in high-speed and high-current systems.
Material Expertise: We utilize nanocrystalline, ferrite, and ferrite-composite cores to achieve low loss, high impedance, and thermal stability under demanding conditions.
EMC Optimization: All designs meet or exceed EMI standards (EN 55032, CISPR 22), minimizing common mode noise in switching circuits and communication lines.
Automotive-Grade Reliability: Products are qualified for -40°C to +125°C operation, with AEC-Q200 testing and IP67-rated encapsulation available.
YET's common mode chokes are widely used in:
Telecom Systems: Signal line EMI filtering, Ethernet/USB/HDMI common mode suppression
Power Electronics: Input/output filtering for SMPS, DC-DC converters, inverters
Automotive Electronics: On-board chargers (OBC), DC-DC converters, battery management systems (BMS)
Industrial Equipment: PLCs, motor drives, CNC controllers, automation power supplies
Renewable Energy: PV inverters, wind power converters, energy storage systems
Whether you're designing compact DC-DC converter circuits or industrial-grade power modules, YET provides the right common mode choke with optimized inductance, impedance, and current ratings.
We supply a broad selection of common mode chokes, including:
High Current Common Mode Choke
SMD Power Inductor for DC-DC Converters (with common mode filtering capability)
UU Type Common Mode Choke
Toroidal Common Mode Choke
Custom shapes & windings based on your EMC layout
All models can be customized for frequency range, current rating, leakage inductance, insulation, and mounting method.
YET supports global customers with fast-turn OEM & ODM common mode choke development, using advanced simulation tools such as Maxwell, HFSS, and Icepak to co-optimize magnetic, thermal, and structural performance. Prototypes can be delivered in as little as 7 days.
In addition to custom solutions, we also maintain inventory of standard common mode chokes for fast delivery.
