High-frequency magnetics from 1 to 150 W, wound and tested in GaoChangSheng's factories in China. Samples in 3–5 days. Production orders from 500 to 20,000 pieces.
Every part is built to your specification: your circuit, your safety requirements, your footprint. Send a drawing, a datasheet, or the part number you use today and we will propose an equivalent.
Typical applications: chargers and adapters, LED drivers, home appliances and BLDC motor drives, smart building controls and industrial power supplies.
GaoChangSheng has manufactured magnetic components since 2010. Winding runs on automatic and multi-spindle machines across four sites in China.
| Site | Staff | Pieces per day |
|---|---|---|
| ShenzhenHeadquarters, since 2010 | 242 | 700,000 |
| RuijinSince 2021 | 98 | 680,000 |
| DongguanSince 2020 | 80 | 400,000 |
| HengyangSince 2018 | 80 | 170,000 |
| Total | 500 | 1,950,000 |
Finished transformers run through automatic test lines. Robot handlers load the parts into hi-pot and transformer testers that check insulation strength, winding resistance and inductance.
Two companies, each with a clear job. You get the manufacturer's engineering and capacity, and one partner for quotes, contracts and export.
Manufacturer
Designs and manufactures the parts at its own plants in Shenzhen, Dongguan, Hengyang and Ruijin. Factory audits take place at GCS.
International sales and contracting
GCS's authorised international sales partner. HYH prepares quotations, signs contracts, invoices and arranges export shipping for customers outside China. Payments go to HYH's company account, as stated on every proforma invoice.
