Import Aluminum Electrolytic Capacitors In Series — Buy in Bulk from Supplier in China

Yiyang Pengcheng Technology Development Co., Ltd. manufactures radial-lead aluminum electrolytic capacitors from its base in Yiyang, Hunan Province, China. The product range spans model families CD11G, CD11GA, CD11GC, CD11GE, CD11GAL, CD11GCL, and CD11GEL, with rated voltage from 10 V to 450 V and capacitance from 1 microfarad to 100 microfarad. Load life is specified between 300 uptime records. Operating temperature range covers minus 40 °C to plus 105 °C, with capacitance tolerance of minus 10 percent to plus 20 percent measured at 120 Hz and 25 °C. The company states RoHS and ICQ certifications, with stated production capacity of one hundred million pieces per month. Key features cited include low leakage current, high ripple current capability, low dissipation factor, low impedance and ESR, and extended load life from 6000 hours to 15000 hours depending on series.

The radial terminal format with cylindrical aluminum case is the dominant construction for through-hole printed circuit board mounting in consumer, lighting, and industrial electronics. The voltage range from 10 V to 450 V spans low-voltage digital circuits through mains-connected applications such as LED drivers and energy-saving lamp ballasts. Capacitance tolerance of minus 10 percent to plus 20 percent at 120 Hz is standard for general-purpose electrolytics, though tighter tolerances are available in specialty grades. The wide temperature range of minus 40 °C to plus 105 °C supports outdoor and thermally stressed indoor environments. Low ESR and high ripple current are particularly valued in switch-mode power supply output filtering, where self-heating from ripple current is a dominant failure mechanism. The extended load life figures of 6000 hours to 15000 hours suggest the availability of higher-grade series beyond the base 3000-hour to 12000-hour range.

Primary applications include LED drivers, compact fluorescent and LED retrofit lamps, general consumer electronics, household appliances, and broad industrial use. The supplier targets battery applications, lighting OEMs, and appliance manufacturers seeking standard and long-life radial electrolytics. Packaging is stated as 250 pieces per bag or to buyer order, with carton quantities of 10000 pieces. Sample provision is described as free of charge. OEM and ODM services are offered, indicating willingness to customize case size, lead form, and marking. Buyers should note that the supplier's stated ISO9001:2008, ISO14000:2001, and RoHS certifications appear in the source description, but buyers should verify current certificate validity and scope directly with the company or through accredited registrar databases.

Yiyang Pengcheng Technology Development Co., Ltd. is located at Yiyang, 413000, Hunan Province, China. The company was founded in 1988 according to its own description, giving it over three decades of reported history in aluminum electrolytic capacitor manufacturing. The supplier holds an 'imported' tier and 'harbor' trust tier, with zero percent response rate and zero average response hours recorded on the platform. These engagement metrics are untested, so buyers should not assume responsiveness and should use multiple contact channels for initial outreach.

The supplier describes itself as specializing in radial electrolytic capacitors for general purpose, LED driver, lighting, and high-capacitance applications. It states offices in Beijing, Shenzhen, Zhongshan, and Hangzhou, suggesting a domestic sales network, and reports export to India with planned expansion to the Americas and Asia. The source mentions ISO9001:2008, ISO14000:2001, and RoHS compliance, though buyers should request current certificate copies and verify scope. No specific revenue, factory floor space, employee count, or named major customers are provided, and none should be invented. The stated monthly production capacity of one hundred million pieces indicates a mid-scale operation by industry standards.
