Yu Yang Magnetic Co., LTD. (YET) is a trusted shielded coupled inductor manufacturer, offering a full range of high-efficiency, low-noise magnetic components for power electronics, DC-DC converters, telecom systems, and automotive applications. With advanced magnetic design, multi-physics simulation, and lean manufacturing capabilities, we supply custom inductors and standard shielded coupled inductors that meet the industry's demanding power density and EMI requirements.
A shielded coupled inductor integrates two or more magnetically coupled windings with an external magnetic shield, allowing for improved current sharing, reduced EMI, and enhanced thermal performance. It is widely used in:
Multiphase DC-DC converters
Power modules for telecom and computing
Automotive battery management systems
High-efficiency synchronous buck or boost converters
Customizable Windings & Core Materials: Litz wire, flat wire, or PCB windings available for optimized current handling and core loss reduction.
EMI Shielding Options: Magnetic or copper shielding significantly reduces radiation, supporting EN 55032/Class B compliance.
Thermal & Structural Reliability: Designed for long-term stability under high switching frequency, thermal cycling, and vibration (AEC-Q200 available).
Compact Footprint, High Power Density: Optimized for high-density PCB layout with low profile and minimal parasitic losses.
Our shielded coupled inductors are widely used in power-critical and EMI-sensitive systems, such as:
Automotive Power Electronics
e.g., 48V to 12V dual-phase DC-DC converters, on-board charging modules
Telecom & Data Center Equipment
e.g., multiphase POL converters, isolation circuits for power modules
Industrial Automation
e.g., servo drives, motion control systems, low-noise power rails
Battery Management & Energy Storage
e.g., bidirectional converters, BMS current balancing circuits
We offer a wide variety of shielded coupled inductor models, supporting:
Various inductance values (1μH to 100μH+)
Rated current up to 50A+
Footprints from ultra-compact SMD to through-hole packages
Different winding topologies for optimized coupling coefficient (K)
Whether you need a standard model for quick integration or a customized inductor for a complex topology, we have the solution.
With in-house core processing and advanced simulation tools (Maxwell, HFSS, Icepak), YET delivers fast-turn OEM & ODM shielded coupled inductor solutions. We support quick sampling, prototyping, and volume production for both standard and complex magnetic designs.
