Ultra-fine enameled copper wire

Enameled copper wire QA-1/155 diameter 0.071mm

Core Product Features

Excellent Electrical Conductivity

Copper itself is a high-quality conductive metal with high conductivity and low resistance loss. Even in the ultra-fine specification, it can maintain efficient power transmission under small-current working conditions, making it suitable for signal and power conduction in precision circuits.

Stable Insulation Protection

The surface-coated insulation layer (common types include polyester enamel, polyurethane enamel, polyimide enamel, etc.) has high dielectric strength, temperature resistance and chemical corrosion resistance. It can effectively isolate the copper conductor from the external environment, prevent faults such as short circuits and electric leakage, and adapt to various harsh working scenarios.

Superior Machinability

The wire has excellent flexibility, enabling winding with a tiny radius without easy breakage or enamel peeling. It can meet the precision winding processing requirements of components such as micro-motors and inductors.

Precise Dimension Control

During the production process, the diameter tolerance can be controlled within ±0.002mm, and the enamel layer thickness is uniform, ensuring consistency and stability in mass applications and improving the yield rate of end products.

Main Application Fields

Micro-motors and Motors

Such as smartphone vibration motors, UAV gimbal motors, small fan motors, etc. Ultra-fine wire windings can achieve high power density energy conversion in limited space.

Electronic Components

High-frequency inductors, SMD transformers, miniature current transformers, etc. With low resistance and stable insulation characteristics, they ensure signal transmission accuracy in high-frequency circuits.

Consumer Electronic Devices

Internal wiring and windings of portable devices such as Bluetooth headsets, smart watches, and laptop cooling modules, adapting to the development trend of miniaturization and lightweight of products.

New Energy and Automotive Electronics

On-board sensors of new energy vehicles, precision components of battery management systems (BMS), and high-frequency conversion components of charging piles, meeting the requirements of high temperature resistance and high reliability.

Medical Devices

Such as portable electrocardiographs, micro-pumps, medical sensors, etc. The high precision and stability of ultra-fine wire can ensure the accurate operation of medical equipment.
