High-Flexibility Taped Litz Wire for High-Frequency Inductors

Taped Litz Wire is specifically designed to tackle the challenges in high-frequency electrical applications, offering superior performance through its unique construction. By intertwining individually insulated strands and then applying a specialized tape insulation, this wire effectively reduces AC losses, such as skin and proximity effects, making it ideal for use in power electronics where efficiency is critical.

Overview


The High-Flexibility Taped Litz Wire is a specialized conductor designed for high-frequency inductors and transformers requiring both low eddy current losses and mechanical agility. Comprising hundreds of fine enameled copper strands wrapped in a high-temperature polyester tape, this wire balances the benefits of litz construction with enhanced winding stability for compact, high-performance magnetic components.


Features


Optimized Strand Count: 200-800 strands of 0.01-0.05mm diameter wires reduce skin effect up to 40% at 50kHz, outperforming solid-core wires in high-frequency circuits.

Tape Reinforcement: Low-friction polyester tape allows 360° flexing without strand separation, making it ideal for applications with dynamic movements or tight coil geometries.

Thermal Class H Rating: Withstands continuous operation at 180°C, suitable for power-hungry switch-mode power supplies and wireless charging coils.

Low Capacitance Design: Spaced strand layering and non-conductive tape minimize inter-strand capacitance to <5pF/m, reducing resonant frequency shifts in tuned circuits.

Precision Insulation: Uniform enamel coating on each strand ensures consistent dielectric strength (200V per strand), enhancing overall wire reliability.


Application


Wireless Charging Pads: Enables efficient power transfer in Qi-compliant chargers by minimizing losses in resonant inductors.

RF Filter Inductors: Used in cellular base station filters to maintain signal purity across wide frequency bands.

LED Driver Transformers: Reduces energy loss in high-frequency (100kHz+) dimming circuits, improving overall system efficiency.

Medical Imaging Coils: Suitable for MRI gradient coils requiring low noise and precise electromagnetic field control.


Faq


Q: Can the tape be specified in different colors for circuit identification?

A: Yes, we offer colored tapes (black, white, red) for easy differentiation in multi-wire harnesses.

Q: What is the minimum recommended soldering temperature?

A: Use a soldering iron set to 300-350°C to avoid damaging the enamel coating; pre-tinning strands improves joint reliability.

Q: How does humidity affect the tape's adhesive properties?

A: The tape uses a moisture-resistant adhesive rated for 95% relative humidity, ensuring long-term strand retention in damp environments.
