Super Thin 0.03mm X 4000 Strands Natural Silk Covered Litz Wire For Wireless Charger Coils High Frequency Copper Stranded Wire

When it comes to high frequency power transmission, skin effect and proximity effect are efficiency robbing demons. Our Litz wire is designed to overcome these issues, and our highest grade offering - the Super Thin 0.03mm x 4000 Strands Natural Silk Covered Litz Wire - is the apex of this technology.

Construction and Composition
This nylon serving litz wire is based on a complex bundle of 4,000 strands of ultra fine, solderable enameled copper wire. Each individual strand is only 0.03mm in diameter- thinner than a strand of human hair. These strands are carefully twisted together to create one conductor. This special lay-out ensures that high-frequency currents flow on the surface of all the strands and thus minimizing the ac resistance and the eddy currents losses. We wrap the litz wire with natural silk. This final layer not only offers great electrical insulation, but also provides a high degree of flexibility and durability allowing the wire to be pulled through conduit without breaking.

Revolutionizing Wireless Charging

This is the best arrangement for high-performance wireless charging coils. With current Qi-standard and proprietary fast-charging solutions, the frequencies used are in the 100kHz to a few MHz (range). At such frequencies a solid copper wire would have its power severely dissipated. Our 0.03mm x 4000 strands Litz wire on the other hand dramatically reduces these losses and allows for higher Q-factors and more efficient power transfers. With such speeds, you’ll get less heat generation and a cooler operating temperature for your wireless power modules – making it ideal for high-end smartphones, wearables and electric vehicle (EV) wireless charging pads.

Versatile Applications
While wireless charging is the main use case, this wire has many other uses. It’s also a good choice for high-frequency transformers and inductors used in switching power supplies and server power units, due to its high frequency capability with very low loss. And because of its pliability and light weight, it is very desirable in the audio industry for voice coils (speaker coils) where the fastest response and lowest distortion are key. Any application that demands a high-frequency performance but also needs mechanical flexibility and good thermal stability can take advantage of this sophisticated conductor.Full Customization and Prototyping
We know every app is different. That's why our Litz wires covered with silk can be customized completely. Our resources are virtually limitless, and by that we mean specifically applicable to your needs:

 Conductor Diameter: Single wire sizes from 0.025mm to 0.5mm.

 Thermal Class: Suitable for use in thermal environments of different levels with insulation grades 155°C (Class F), 180°C (Class H), and 220°C (Class C).

Strand Count: From one strand up to an immense 12,700 strands options, subject to your power requirements.

 Construction: The twisting pitch and tension of the silk can be varied to suit your application.

Our commitment is to help bring the best ideas to life at every stage of innovation. From R&D prototyping to small-batch production for specialized equipment, we’re here to help. We accept small batch custom orders so do get in touch with us. We strive to provide you with a tailor made solution that addresses exactly your engineering requirements.
