About Core Ray Electronics Co., Ltd - Electric Chokes & Ballast Supplier in China

Core Ray Electronics Co., Ltd is based in China and lists five distinct products in its catalogue. The company classifies its offerings under the Electric Chokes & Ballast category, which includes transformers, chip inductors, common‑mode chokes, choke coils and ET/UT common‑mode chokes. Two of the items - the choke coil and the ET and UT common‑mode choke - are recorded with HS code 8504.50, covering electrical transformers and static converters. Materials specified are electrolytic copper windings with a laminated iron core for the choke coil, and a ferrite core with oxygen‑free copper windings for the ET/UT choke. The remaining products are listed without HS codes in the supplied data.

Product Range and Specialties of Core Ray Electronics Co., Ltd

In the transformer segment, exporters from China typically supply units ranging from 0.5 kVA to several hundred kVA, with IEC 60076‑1 compliance for temperature rise and dielectric strength. Chip inductors are usually offered in standard EIA‑E series values from 1 nH to 10 µH, with tolerance bands of ±5 % or ±10 % and current ratings up to 1 A. Common‑mode chokes for power electronics often feature ferrite cores with inductance between 0.1 mH and 10 mH, and a rated current of 5 - 30 A, meeting IEC 60205. The choke coil listed with electrolytic copper windings and laminated iron cores aligns with traditional power‑line chokes that target low‑frequency applications and are tested for saturation flux density around 1.5 T. The ET and UT common‑mode choke with a ferrite core and OFC windings is typical for high‑frequency EMI suppression, where a low DC resistance and high impedance at 100 kHz - 10 MHz are required.

Trade and Export Information - Core Ray Electronics Co., Ltd

Chinese manufacturers of electric chokes and transformers primarily ship to the United States, European Union, and Southeast Asian markets, where demand is driven by automotive, renewable energy and industrial automation sectors. HS code 8504.50 subjects the products to customs inspections for compliance with IEC standards and, where applicable, RoHS and REACH restrictions in the destination country. Standard export documentation includes a commercial invoice, packing list, Certificate of Origin and test reports such as IEC 60205 for inductors or IEC 60076 for transformers. Products are commonly packed in anti‑static polyethylene bags inside double‑wall cardboard cartons, with container loads ranging from a 20 ft container (approximately 1,200 units of small chokes) to a 40 ft container (up to 2,500 units) depending on size. Shipping terms often follow CIF or FOB, and buyers should verify that the supplier can provide pre‑shipment inspection reports from recognized laboratories.

Sourcing from Core Ray Electronics Co., Ltd - Buyer Guidance

Buyers should request a detailed datasheet that lists inductance, DC resistance, saturation current, temperature rise and applicable IEC test results for each choke or transformer. For the choke coil and ET/UT common‑mode choke, confirm the material certifications of the copper windings (e.g., oxygen‑free copper grade) and core composition, as these affect loss and performance at high frequencies. It is prudent to ask for RoHS compliance statements and, where required by the destination market, REACH registration or CE marking documentation. Sample units should be evaluated for impedance versus frequency and for mechanical robustness under vibration if intended for automotive use. Verify that the supplier can provide third‑party inspection certificates, such as SGS or BVQI, prior to full‑scale production.

What types of inductive products are listed by Core Ray Electronics Co., Ltd?

The catalogue includes a transformer, chip inductors, generic common‑mode chokes, a choke coil with electrolytic copper windings, and an ET/UT common‑mode choke with a ferrite core and oxygen‑free copper windings.

Which HS code is associated with the choke coil and ET/UT common‑mode choke?

Both the choke coil and the ET/UT common‑mode choke are recorded under HS code 8504.50, which covers electrical transformers and static converters.

Are the listed chokes expected to meet IEC standards?

Buyers should request test reports confirming compliance with IEC 60205 for inductors and IEC 60076 for any transformer‑type items. The supplier’s documentation can verify whether the products have been tested to those standards.

What certifications should I request from this supplier before purchase?

Since no certifications are listed in the supplied data, buyers should ask for RoHS compliance, REACH registration (if exporting to the EU), and any applicable CE or UL certificates, together with third‑party inspection reports.

How are the products typically packaged for export?

Export packs usually consist of anti‑static polyethylene bags placed inside double‑wall cardboard boxes, with cartons palletised for container loading.

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

Typical minimum order quantities for small chokes range from 1,000 to 5,000 pieces, while transformers may start at 100 units. Lead times are generally 30‑45 days after order confirmation, depending on the specific product and required testing.

How can I obtain a sample for performance evaluation?

Request a pre‑production sample together with the full datasheet and test report; most Chinese exporters provide a small quantity (often 5‑10 units) under a non‑binding sample agreement.

Which regions does Core Ray Electronics mainly export to?

The supplier’s export profile aligns with typical Chinese choke and transformer exporters, targeting the United States, EU member states and Southeast Asian countries such as Vietnam, Thailand and Malaysia.
