LH Capacitors is the SMD aluminum electrolytic capacitor line of Dongguan Lianghua Electronic Technology Co., Ltd. — focused on the R&D and production of aluminum chip electrolytic capacitors since 2018. With 70+ automated lines, a 20,000 m² factory base and 200+ staff, we control every step of the process in-house.
Our story starts in Dongguan with RMB 5 million of registered capital and a single focus: SMD aluminum electrolytic capacitors. Every step since has deepened that focus.
The story of Lianghua starts in Dongguan: registered capital of RMB 5 million, focused on the R&D and production of aluminum chip electrolytic capacitors.
Built the business base from scratch and opened up new territory in the market.
Introduced a standardized process to shape team execution — every process step and standard strictly enforced in production.
Streamlined the flow and consolidated quality across the line.
Annual output broke through 1.2 billion pieces; certified for quality, occupational health & safety and environmental management systems. Factory area grew from 1,500 m² to 15,000 m², automated lines from 13 to 70+, headcount to 128.
Five years since the company was formally established — pushing forward into broader markets with higher, further and brighter goals.
Owned manufacturing, controlled materials, a standardized process and an in-house R&D loop — the things that keep quality, yield and delivery stable at volume.
Raw materials come from imported or top-tier domestic brands. Every new supplier is qualified through full material-characteristic testing, and approved-supplier evaluation is enforced as the first gate of quality control — so part performance and consistency start at the source.
70+ automated lines cover the full range of case sizes, so we deliver differentiated products and services. Continued process investment lets us build smaller, higher-performance capacitors — down to 4×4.5 mm and 5×4.5 mm cases.
Experienced technicians follow documented equipment procedures, process specs and work instructions. A standardized flow makes production clear, consistent and efficient — and keeps quality stable at volume.
Development follows a rigorous, ordered process built on international standards and specific customer needs. From kickoff to mass production, every step is documented and validated, so new products land on spec and on time.
Certificates are issued to Dongguan Lianghua Electronic Technology Co., Ltd. (organization code 91441900MA5268408Q) and are verifiable through the issuing body's registry.
