Import Aluminum Electrolytic Capacitors — Buy in wholesale FOB from Supplier in Hong Kong

JB Capacitors manufactures aluminum electrolytic capacitors in snap-in, screw, lug, and radial terminal configurations, with voltage ratings spanning 10V to 500V and capacitance from 1uF to 500,000uF. The construction uses aluminum foil electrodes with an electrolyte-impregnated paper or synthetic polymer separator, all housed in an aluminum can with a vented safety top. These components serve as energy storage and ripple filtering elements in DC power supplies, where their high volumetric efficiency outweighs shorter lifetime expectations compared to film or ceramic alternatives.

The product line targets industrial power electronics, including motor drives, renewable energy inverters, and switched-mode power supplies. JB Capacitors emphasizes RoHS compliance across its series, though buyers should verify whether specific part numbers carry additional environmental certifications such as REACH or halogen-free status. The snap-in and screw types suit high-current applications requiring mechanical stability, while radial types address general-purpose board mounting. Standard operating temperatures for these series typically range from -40°C to +105°C, with lifetime ratings doubling for every 10°C reduction in core temperature below maximum.

OEMs and contract manufacturers in industrial equipment, telecommunications infrastructure, and consumer appliance sectors represent the primary buyer base. Container-load orders receive preferential pricing, though exact MOQ and lead time figures are not stated in the listing and require direct confirmation with JB Capacitors. The supplier's Hong Kong registration with Guangdong manufacturing presence suggests mainland China production with potential logistics advantages through Shenzhen or Hong Kong port facilities. Buyers should clarify whether technical documentation, including spice models and lifetime calculation tools, accompanies sample shipments.

JB Capacitors operates with a registered address on Yanhuxi Road in Dongguan, Guangdong, with Hong Kong affiliation, placing its manufacturing footprint in China's Pearl River Delta electronics manufacturing cluster. The supplier tier is marked as imported with a harbor trust designation, indicating platform-processed profile data rather than independently verified credentials. Notably, the response rate shows 0.00 with zero average response hours recorded, which signals either a new listing, inactive account, or data collection gap rather than necessarily reflecting current responsiveness.

The company positions itself as a manufacturer and marketer of aluminum electrolytic capacitors across multiple terminal configurations, claiming top quality in China with reasonable prices. The listing does not disclose factory size, annual output, R&D investment, or employee count, nor does it name specific quality management certifications such as ISO 9001 or IATF 16949. Buyers should independently verify manufacturing capability, quality system registration, and whether JB Capacitors owns production facilities or operates through subcontracted arrangements. The absence of named client references or export market history requires direct inquiry during qualification.
