Import Aluminum Electrolytic Capacitor — Buy in Bulk from Supplier in Hong Kong

Sun Hing Electronics supplies aluminum electrolytic capacitors rated for 6.3V to 450V with capacitance values from 4µF to 18µF. These components are built for energy storage and discharge in electronic circuits where stable performance under load is critical. The capacitors feature low Equivalent Series Resistance (ESR) and optimised ripple current handling, both of which reduce heat generation and improve efficiency in switched-mode power supplies.

The construction uses an etched aluminum foil anode and electrolyte-impregnated separator, standard for radial-lead aluminum electrolytic types. Typical operating temperature ranges for this category span -40°C to +105°C, though the exact thermal limits for this series should be confirmed directly with Sun Hing Electronics. The capacitors are suited to through-hole mounting, with cylindrical aluminum cans and PVC or PET sleeve insulation. Shelf life and load life ratings are key parameters to verify, as they determine replacement intervals in industrial equipment.

Buyers in electronics manufacturing, automotive control modules, and telecommunications infrastructure use these capacitors for smoothing, coupling, and decoupling applications. Power supply designers value the low ESR for reducing output voltage ripple. Audio equipment manufacturers employ them in amplifier power stages. Before ordering, confirm with Sun Hing Electronics the exact load life at rated temperature, the ripple current rating at 100kHz, and whether the parts comply with RoHS and REACH directives.

Sun Hing Electronics is based at Kowloon Bay Industrial Center in Kowloon, Hong Kong, operating from a location within one of the territory's established industrial zones. The company is classified as an imported-tier supplier with a harbor trust tier. Its response rate is recorded at 0.00 percent, and its average response time is zero hours, which indicates that direct communication through the platform has not yet been established by buyers.

The supplier listing does not state manufacturing certifications, ISO accreditation, factory size, or years in business. No client references, production capacity figures, or revenue data are provided. Buyers should treat the profile as unverified beyond its registered address and tier classification, and conduct independent due diligence including a request for business registration documents, quality management system certificates, and sample evaluation before committing to volume orders.
