Product Description

0.032mm Enameled Copper Magnet Wire For High-Precision Current Sensors

This ultra-fine enameled copper magnet wire is specifically engineered for high-precision current sensors, offering exceptional performance in demanding applications.

Core Characteristics

Why use such fine PU enameled wire?

Ultra-fine diameter: Enables miniaturized coil winding, meeting the requirements of product miniaturization and high density.

Polyurethane (PU) Enamel Coating Characteristics

Direct solderability: During high-temperature soldering, the enamel layer can be directly melted and tinned without pre-peeling, greatly improving production efficiency and automation, and avoiding damage to the extremely fine wire.
High-frequency performance: Relatively low dielectric loss, suitable for high-frequency signal transmission.
Solvent resistance: Withstands chemicals in processes such as impregnation and encapsulation.

High conductivity: The copper core provides an excellent conductive foundation.
