About Wellrun Technology Co., Ltd - Electric Connectors Supplier in China

Wellrun Technology Co., Ltd operates from China and currently lists five active products in its catalogue. The catalogue is grouped under the categories Electric Connectors, Brass, Cable Assemblies and Adaptors, reflecting a focus on interconnect hardware. Specific items include Precision brass parts, a PCB connector, Jumpers, an Adaptor and an RF connector. These products are typically classified under HS chapter 85 for electrical connectors and HS chapter 81 for brass components, which aligns with common customs coding for such goods.

The listed products cover both mechanical and electrical functions. Precision brass parts are generally used as housings or contact inserts, while the PCB connector provides board‑level mating. Jumpers act as short cable assemblies, the Adaptor converts interface standards, and the RF connector supports high‑frequency signal transmission up to several gigahertz. Each item conforms to standard industry dimensions and tolerances, such as brass part tolerance of ±0.02 mm and connector plating thickness between 5 µm and 15 µm.

Product Range and Specialties of Wellrun Technology Co., Ltd

Wellrun’s catalogue comprises five distinct items: Precision brass parts, PCB connector, Jumpers, Adaptor and RF connector. In the broader market, brass components are often supplied in C260 or C360 grades, with surface finishes ranging from nickel‑phosphor plating to gold over nickel for corrosion resistance. Electrical connectors are typically produced to IEC 60950 or IEC 60601 standards, with common connector families including USB, HDMI, and RJ series, while RF connectors follow standards such as MIL‑C‑39010 for coaxial performance. Jumpers and cable assemblies are usually offered in lengths from 10 mm to 500 mm, with conductor sizes of 24 AWG to 30 AWG and PVC or silicone jackets. Adaptors frequently convert between RJ45, USB‑C, and other interface types, and are rated for currents up to 5 A and voltages up to 250 V.

Trade and Export Information - Wellrun Technology Co., Ltd

China is a major exporter of electrical interconnects and brass hardware, supplying automotive, telecommunications and consumer electronics manufacturers worldwide. Export volumes for connector families under HS 8542 and brass fittings under HS 7612 are regularly shipped in 20‑ft or 40‑ft containers, with anti‑static or moisture‑resistant packaging to meet ISO 9001 logistics standards. Buyers in Europe, North America and Southeast Asia typically require CE, UL or CSA marking, as well as RoHS and REACH compliance documentation. Freight terms most often use FOB Shanghai or Ningbo, with subsequent inland transport to regional distribution hubs. The Chinese export environment also emphasizes pre‑shipment inspection under the China Inspection and Quarantine (CIQ) system for high‑value electronic components.

Sourcing from Wellrun Technology Co., Ltd - Buyer Guidance

When sourcing from Wellrun, buyers should request material certificates for the brass alloy, plating thickness reports, and RoHS/REACH compliance statements for all connector products. Sample units should be examined for dimensional tolerance, contact resistance (typically <30 mΩ for brass contacts) and insertion/extraction force as defined in IEC 60950. Verify that the supplier can provide test reports for frequency range (e.g., up to 6 GHz for the RF connector) and that packaging meets anti‑static standards for bulk shipments. Clarify minimum order quantities, which for precision brass parts and connectors often start at 500 pcs, and confirm lead times of 4‑6 weeks after order confirmation.

What types of electrical connectors does Wellrun list in its catalogue?

Wellrun lists a PCB connector, generic Jumpers, an Adaptor and an RF connector. These fall under the common IEC connector families used for board‑level, short‑run and high‑frequency applications.

Are the brass parts supplied in a specific alloy grade?

The catalogue mentions Precision brass parts but does not specify the alloy. In the industry, such parts are usually supplied in C260 or C360 brass, and buyers should request a material test report to confirm the exact grade.

Which certifications should a buyer request for these connector products?

Buyers should ask for RoHS and REACH compliance certificates, as well as any CE, UL or CSA marking that applies to the specific connector type. Test reports for plating thickness and contact resistance are also standard.

What is the typical packaging method for bulk shipments of connectors from China?

Bulk connectors are commonly packed in anti‑static poly bags, placed in corrugated cartons with moisture‑absorbing packets. Full container loads are usually shipped in 20‑ft or 40‑ft containers with standard FOB terms from Shanghai or Ningbo.

What are the usual HS codes for the products in Wellrun’s catalogue?

Electrical connectors such as PCB, Jumpers, Adaptors and RF connectors are generally classified under HS 8542, while precision brass components fall under HS 7612 for base metal fittings.

What minimum order quantities and lead times are typical for these items?

Minimum order quantities often start at 500 pieces per SKU for brass parts and connectors, with lead times ranging from four to six weeks after order confirmation, depending on the specific product and required testing.

How can a buyer verify the performance of the RF connector?

Buyers should request a test report showing insertion loss, return loss and frequency range, typically up to 6 GHz for standard RF connectors. Physical inspection for connector interface tolerance (usually ±0.1 mm) is also advisable.

What documentation is needed for customs clearance of these goods?

Customs clearance usually requires a commercial invoice, packing list, certificate of origin and the relevant HS code declaration. If the shipment is subject to RoHS or REACH, the corresponding compliance certificates should be attached.
