About Chaorong Electronics Co., Ltd.
Chaorong Electronics Co., Ltd. is a professional manufacturer of electronic insulation materials, located in Dongguan, Guangdong, China. We operate a complete common mode inductor production line and precision board machining facility. Our core products include SQ and UC flat wire common mode inductors, FR4 fiberglass boards, carbon fiber boards, phenolic (bakelite) sheets, PC boards, and acrylic sheets.
Our products are widely used in power adapters, EV charging stations (OBC on-board chargers), LED drivers, switch mode power supplies (SMPS), industrial control systems, UAV drone frames, and display panels.
Common Mode Inductor Production Line
Our common mode inductors use SQ/UC flat wire automated winding technology, offering these advantages over conventional round wire:
- Higher fill factor — less flux leakage, superior electromagnetic performance
- Low DC resistance (DCR) — reduced heat, improved power efficiency
- High CM impedance — strong high-frequency common mode interference suppression
- Automated winding — consistent quality, ideal for high-volume production
- Custom specifications available to meet unique customer requirements
Common mode inductor specs: inductance 1mH – 50mH, rated current 1A – 30A, wire specs 0.5×3mm / 0.8×4mm (custom available), operating temp -40°C to +125°C, flame rating UL94 V-0 / HB.
Precision Board Machining Capabilities
We offer full-scope precision machining for FR4 fiberglass board, carbon fiber board, phenolic board, PC board, and acrylic sheet, including laser cutting, CNC machining, engraving, screen printing, and lamination. High precision, short lead times, small-batch custom orders welcome.
