High-Quality Power Inductors for Your Needs

--- Why Choose FERRTX Power Inductors? ---

• Precision Customization for Diverse Applications:

FERRTX has built a strong reputation for delivering precision-engineered power inductors tailored to specific application needs. One notable example is our collaboration with Tesla on current transformer design for electric vehicle (EV) charging systems. In this project, Tesla required a high-efficiency, compact SMD power inductor capable of handling high-frequency switching and extreme thermal conditions. Leveraging our 37 years of expertise and advanced simulation tools at our R&D Center in Xi'an, we developed a custom-designed shielded inductor (HM series) with optimized core material and winding structure. The result was a 15% improvement in power efficiency and a 20% reduction in thermal rise compared to standard components. This solution not only met Tesla’s stringent performance benchmarks but also passed rigorous IATF16949-certified testing protocols. Furthermore, our ability to rapidly prototype and validate designs—supported by a 150-person engineering team and 80% automated smart factories—ensured a fast time-to-market. Clients like Honeywell and Siemens have similarly benefited from our customization capabilities, where we resolved complex EMI/RFI challenges in industrial control systems using custom high-frequency transformers and planar inductors. Our proven track record of solving over 2,300 electromagnetic interference issues globally underscores our deep technical mastery and client-focused innovation.

• Commitment to Quality and Reliability:

Quality is the cornerstone of FERRTX’s operations, reflected in our multi-certified production systems and relentless focus on process excellence. A prime example is our long-term partnership with Schneider Electric, where we supply leaded inductors (LGS series) for their industrial power supplies. These components must endure harsh environmental conditions, including high humidity, vibration, and wide temperature fluctuations. To ensure reliability, we implemented a closed-loop quality control system across our Xianyang General Manufacturing Base, integrating real-time monitoring via IoT-enabled equipment and AI-driven defect detection. Every batch undergoes full functional testing, including thermal cycling, insulation resistance checks, and accelerated life testing. As a result, our defect rate remains below 10 PPM—far below industry average. Additionally, our ISO9001, ISO14001, and IATF16949 certifications are not just paperwork; they represent a culture of continuous improvement. For instance, when a major European telecom client reported intermittent signal loss in their 5G base stations, our Quality Department led a root-cause analysis and discovered a micro-crack in the ferrite core due to improper sintering. We immediately revised our process parameters and introduced a new ultrasonic inspection step, preventing recurrence. This proactive approach has helped us maintain an 80% retention rate among clients with over five years of cooperation. With annual production exceeding 200 million units across four smart factories and a total production area of 12,000 square meters, FERRTX delivers unmatched consistency and dependability.

--- Our Range of Power Inductors ---

• Lead and SMD Power Inductors:

FERRTX offers a comprehensive portfolio of leaded and surface-mount device (SMD) power inductors engineered for high performance and durability. Our LGS series leaded inductors are widely used in power supplies for industrial automation and medical devices, known for their robust construction and excellent thermal stability. One standout case involved Signify (formerly Philips Lighting), which required a high-reliability inductor for LED drivers in outdoor street lighting systems. Traditional inductors failed prematurely due to moisture ingress and thermal stress. We responded by developing a hermetically sealed LGS variant with epoxy-coated windings and a corrosion-resistant casing. Field tests conducted over 18 months showed zero failures across 50,000 units deployed in Nordic climates. On the SMD side, our ERU2314 series flat wire coupled inductors have become a preferred choice for 5G infrastructure manufacturers. Designed for high current density and low DC resistance, these inductors deliver up to 95% efficiency in power conversion modules. A key client, FiberHome, integrated them into their optical network terminals, achieving a 12% increase in output power while reducing heat dissipation. The inductors also passed UL and CE safety certifications, ensuring compliance with global standards. Whether it’s the HM series shielded inductors for sensitive RF circuits or the HDE class D inductors for high-speed digital applications, every product is validated through extensive lab testing and real-world field trials before release.

• High-Voltage and Tunable RF Inductors:

FERRTX excels in manufacturing high-voltage and tunable RF inductors for demanding environments such as aerospace, radar systems, and satellite communications. Our HCB series high-voltage inductors are specifically engineered for applications requiring dielectric strength above 2,000V, making them ideal for medical imaging equipment and industrial test instruments. A significant success story involves Canon Medical Systems, who needed a reliable inductor for MRI gradient coils operating under intense electromagnetic fields. Standard components suffered from insulation breakdown and signal distortion. Our team developed a custom HCB inductor with a dual-layer insulation system and nano-ferrite core, increasing voltage withstand capability by 40% and improving signal fidelity by 30%. The component passed all MIL-STD-810G environmental tests and is now used in over 1,200 MRI machines worldwide. For RF applications, our tunable RF inductors (e.g., TUN series) are pivotal in adaptive filtering and impedance matching networks. A recent project with Nokia for 5G mmWave antennas required inductors that could dynamically adjust resonance frequency based on signal load. Using proprietary tuning mechanisms and embedded piezoelectric actuators, we delivered a prototype that achieved a tuning range of 1.5–3.5 GHz with less than 0.5 dB insertion loss variation. After successful integration into Nokia’s pilot deployment in Finland, the technology is being scaled across multiple 5G sites. These innovations highlight FERRTX’s leadership in pushing the boundaries of magnetic component performance.

--- Industry Applications of Our Inductors ---

• Consumer Electronics and Automotive:

FERRTX’s power inductors are integral to the performance and safety of modern consumer electronics and automotive systems. In the consumer space, our SMD power inductors are widely adopted by brands like Samsung, Lenovo, and Hisense in smartphones, laptops, and smart home appliances. For example, Samsung SDI selected our LCHA series unshielded inductors for use in their latest generation of lithium-ion battery management systems. These inductors provided superior current handling and reduced electromagnetic emissions, contributing to a 10% longer battery cycle life and improved device safety. In the automotive sector, our collaboration with Volkswagen on EV onboard chargers exemplifies our impact. The original inductors in the charger were prone to overheating during rapid charging cycles. We redesigned the inductor using a high-permeability nanocrystalline core and forced-air cooling channels, resulting in a 25% lower temperature rise and a 30% increase in charge throughput. The modified inductor is now standard across several VW ID. series models. Similarly, our pressure sensors and residual current sensors are used in advanced driver-assistance systems (ADAS) and EV battery monitoring. A joint project with Molex for a next-gen charging connector incorporated our custom high-frequency transformers to enable bidirectional power transfer with minimal losses. These applications demonstrate how FERRTX’s components not only meet but exceed the demands of cutting-edge technologies, driving innovation across industries.
