A high-tech enterprise integrating independent R&D, large-scale production, all-round sales and one-stop after-sales service.
We are a high-tech enterprise integrating independent research & development, large-scale production, all-round sales and integrated after-sales service, and a highly competitive professional manufacturer of high-quality electronic components in China. Based on our customers' actual application requirements, we also provide one-stop, personalized customized R&D and production services.
With solid technical strength, the company has accumulated a number of utility model patents and invention patents, forming a sturdy core technology barrier — so every component we deliver is stable, reliable and repeatable in mass production.
From a single production line to a complete portfolio of inductors and resistors.
Yunsheng Electronics Co., Ltd. was established in Dongguan, Guangdong, affiliated with Dongguan Yingsheng Electronic Technology Co., Ltd., focusing on the R&D and manufacturing of electronic components.
Standardized workshops with automated winding, pin welding, tinning and coating lines were put into operation, enabling large-scale production of color ring inductors and I-shaped inductors.
The product lineup was expanded to five core series — color ring inductors, I-shaped inductors, SMD inductors, magnetic ring inductors and wafer resistors — covering a wide inductance and resistance range.
Continuous investment in R&D brought a number of utility model patents and invention patents, together with a standardized quality management system and RoHS-compliant, lead-free manufacturing.
With all-round sales channels and one-stop customization capability, our components are applied in communication, lighting, home appliance, medical, security and industrial control fields, serving customers at home and abroad.
Standardized workshops, automated production lines and full-process inspection — from incoming material to pre-shipment quality control.
Five key steps, each with fixed process parameters and in-process inspection, keep product consistency under control in every batch.
Lead wires are welded onto the element with controlled parameters.
Automated winding ensures accurate turns and stable inductance.
Tinned leads provide reliable solderability for downstream assembly.
Epoxy coating protects the core and improves moisture resistance.
Color ring / laser marking with traceable batch identification.
Clear process zoning, well-lit and well-ventilated workshops managed under a 5S discipline.
Automated winding, tinning and coating equipment supports stable capacity and short lead times.
Incoming material, in-process and pre-shipment inspection keep every batch traceable.
Inductance, dimensions, forming method and lead form can be tailored to customer drawings.
Reliable components, flexible customization and dependable delivery — built on our own R&D and manufacturing capability.
A dedicated R&D team backed by a number of utility model and invention patents. Special core materials deliver high Q value and high self-resonant frequency.
Five core series covering a wide inductance and resistance range. Forming method, sleeve, insulation paint and lead form can all be customized on demand.
Automated winding, tinning and coating lines support stable capacity and short lead times for both standard orders and customized projects.
Epoxy-coated construction ensures high reliability. Products are lead-free and RoHS-compliant, with strong anti-interference capability and low DC resistance.
A standardized quality management system covers material inspection, process control and outgoing testing, so product consistency is maintained batch after batch.
R&D, production, sales and after-sales are integrated in one team — from drawing evaluation and sampling to mass production and technical support.
