Universal coil magnetic separator | a key component for improving wireless charging efficiency

In the current era of rapid popularization of wireless charging technology, universal coil magnetic separators, as the core material for optimizing magnetic field distribution and improving charging efficiency, are receiving widespread attention in fields such as consumer electronics, new energy vehicles, and smart homes. This type of material effectively solves the pain points of electromagnetic interference and high heat generation in wireless charging process through its high magnetic permeability and low loss characteristics. Advanced Institute (Shenzhen) Technology Co., Ltd. (hereinafter referred to as "Advanced Institute Technology") has become an important participant in the field of electromagnetic materials with its technological accumulation.

Universal coil magnetic separatorThe core role of

Universal coil magnetic isolation sheet is a functional material used for wireless charging transmission and reception ends, with its main functions reflected in the following five aspects:

Enhance magnetic field strength: Concentrate the magnetic field generated by the coil through high magnetic permeability characteristics, improve energy transmission efficiency, and make charging speed faster and more stable.
Reduce electromagnetic radiation: shield and absorb excess electromagnetic waves, reduce interference to the human body and surrounding electronic devices, and comply with electromagnetic compatibility (EMC) standards.
Reduce device heat generation: The low loss characteristic reduces the heat generated during energy conversion, improving the safety and service life of wireless charging modules.
Anti metal interference: prevents metal objects from forming eddy currents in a magnetic field, avoiding decreased charging efficiency and local overheating issues.
Improve coil performance: Optimize the quality factor (Q value) and inductance of the coil to reduce energy loss, especially suitable for miniaturized devices such as mobile phones, smartwatches, and car chargers.

For example, in the wireless charging scenario of mobile phones, magnetic separators can improve charging efficiency by 15% -20%, while controlling electromagnetic radiation below national safety standards.

Technical characteristics and application scenarios

The performance of universal coil magnetic separators depends on the material composition and process design. At present, mainstream products are based on soft magnetic materials such as nanocrystals and amorphous alloys, which have the characteristics of thin thickness (0.06-0.10mm), wide temperature resistance range (-25 ℃ to 85 ℃), and excellent high-frequency characteristics (125KHz-13.56MHz). Its application scenarios cover:

Consumer electronics: wireless charging modules for devices such as mobile phones, tablets, TWS earphones, etc;
Smart wearables: miniaturized charging coils for smartwatches and wristbands;
Automotive electronics: In car wireless charging board, new energy vehicle battery management system;
Smart home: wireless charging dock, kitchen appliances, etc.
