Product Overview


Yusheng Electronic’s Customized Self-Bonding Copper Coil is a high-performance electromagnetic component engineered for precision-driven automotive and electronics applications. Crafted with a premium 4UEWF conductor—a key material ensuring exceptional conductivity—the coil features a bright yellow insulation layer (0.1 ± 0.01 mm thickness) that guarantees safety by preventing short circuits. With 14 tightly wound turns and a dual coil connection, this coil balances flexibility and reliability, while its compact dimensions (minimum inner diameter 21 mm, maximum outer diameter 36 mm) make it ideal for space-constrained devices. The single conductor diameter (0.1 ± 0.005 mm) and optimized leave line length (45-50 mm) further enhance its adaptability for high-frequency operations and easy installation.


As a leading manufacturer of self-bonding copper coils, Yusheng Electronic adheres to strict quality control standards to deliver durable, consistent products. Every coil undergoes precision engineering to meet industry demands for reliability, ensuring it performs seamlessly in harsh automotive environments and high-performance electronic devices. We offer both wholesale and custom orders, with global shipping options to serve B2B clients worldwide—making our customized copper coil a top choice for aftermarket solutions and original equipment manufacturing (OEM) partnerships.

Key Benefits & Value Propositions


Superior Conductivity with 4UEWF Conductor

The 4UEWF conductor at the core of our coil enables efficient energy transfer, a critical advantage for electronic transformers and automotive relays. Unlike standard conductors, it minimizes energy loss, ensuring devices operate at peak efficiency—reducing power consumption and extending component lifespan.

Enhanced Stability & Reduced Electromagnetic Interference

Our self-bonding copper coil is designed to mitigate electromagnetic interference (EMI), a common challenge in high-frequency applications. The self-bonding insulation layer secures windings tightly, reducing vibration and signal disruption—making it perfect for sensitive electronics like smartphones and smart home appliances.

Durable Insulation for Safe Operation

The yellow insulation layer (0.1 ± 0.01 mm) is not only durable but also resistant to wear and tear, even in extreme temperatures and harsh automotive conditions. This ensures long-term safe operation, preventing short circuits and minimizing maintenance costs for end-users.

Compact Design & Flexible Dual Coil Connection

The dual coil connection offers versatility, allowing the coil to integrate into diverse circuit designs—from automotive relays to small electronic motors. Its compact footprint maximizes space efficiency, a key requirement for modern miniaturized electronics and automotive components.

Easy Installation with Optimized Leave Line Length

With a leave line length of 45-50 mm, our coil simplifies installation, reducing assembly time and labor costs for manufacturers. The standardized yet flexible design ensures compatibility with various mounting configurations, eliminating the need for custom adapters.

Tailored Customization for Diverse Needs

We understand that every application has unique requirements—our customized copper coil offers flexible options for size, number of turns, insulation thickness, and color. Whether you need a coil for a specialized automotive system or a consumer electronic device, we deliver tailored solutions to match your exact specifications.


Applications


Automotive Industry Applications

Our self-bonding copper coil is a reliable choice for automotive relays, which require consistent performance in extreme temperatures, vibration, and moisture. It also integrates seamlessly into automotive electronic systems, including ignition modules, sensor circuits, and power management units—enhancing vehicle reliability and performance.

Electronics Industry Applications

In the electronics sector, this coil excels in electronic transformers, where efficient energy transfer is critical. It also boosts performance in consumer electronics such as smartphones, smart home appliances (e.g., smart speakers, thermostats), and small motors—delivering stable power and reducing EMI for a smoother user experience. Additionally, it’s suitable for high-frequency inductors used in power supplies and signal processing equipment.


FAQ


What makes a self-bonding copper coil different from standard copper coils?

Unlike standard coils that require external bonding agents, our self-bonding copper coil uses self-adhesive insulation to secure windings. This design enhances stability, reduces EMI, and simplifies manufacturing—making it more reliable for high-stress applications.

Can this coil be customized for my specific automotive or electronics project?

Yes! We offer full customization for size, number of turns, insulation thickness, conductor type, and color. Contact our team to share your specifications, and we’ll deliver a tailored customized copper coil for your needs.

Is the coil suitable for high-frequency applications?

Absolutely. The 0.1 ± 0.005 mm single conductor diameter and tight winding design make it ideal for high-frequency operations, such as those in electronic transformers and signal processing devices.

What is the temperature range this coil can withstand?

Our self-bonding copper coil is engineered to perform reliably in temperatures typical of automotive and consumer electronics environments (from -40°C to 125°C). For extreme temperature requirements, contact us for specialized insulation options.
