• High Performance and Reliability: Premium coil inductors boast high efficiency and reliability, ensuring stable operation across diverse environmental conditions, making them indispensable components in numerous electronic devices and systems.

Main Power Electric offers tailored coil inductor customized solutions to meet specific application requirements. This includes designing coil inductors with precise dimensions, inductance values, and power ratings, ensuring complete alignment with customer needs.

Common mode choke is widely used in power electronic devices. The main roles of common mode choke in electronic circuits include energy storage, filtering, choke, and resonance.

A common mode choke is an electronic component that is used to filter out electromagnetic interference (EMI) from electronic circuits. This improves the performance and reliability of the circuit.

Main Power Electric is a professional problem solver that offers EMI common mode chokes. Our RD team can solve the EMI with you!

Air-core coil inductors differ from traditional coils as they lack an iron core in the middle, contributing to their low magnetic coupling and minimal hysteresis characteristics. This design makes them ideal for various high-frequency and permeability-demanding applications.

• High-Frequency and Permeability Design: Due to the absence of an iron core, air-core coils exhibit excellent permeability for high-frequency signals, making them suitable for high-frequency circuits and communication devices. Additionally, this design reduces magnetic coupling, minimizing interference between circuits.
• Compact and Lightweight Design: With their iron-free composition, air-core coils typically feature smaller dimensions and lightweight attributes, making them particularly favored in space-constrained applications. For instance, in wireless communication devices and RFID systems, the compact design of air-core coils enhances system integration and performance.

As a professional air coil manufacturer, Main Power Electric offers tailored air-core coil customized solutions to meet specific application requirements. This includes designing coils with specific frequencies, inductance values, and dimensions to ensure complete alignment with customer needs. Main Power Electric has an independent workspace to separate other product lines. Besides the automated manufacturing, we have a series of QC stations to control the quality.

Line filter or noise filter refers to an electronic filter installed between electronic equipment and its power supply. Its purpose is to reduce electromagnetic interference on the power line between the equipment and the power supply.
