Choke coil
This choke coil is constructed with electrolytic copper windings and a laminated iron core, designed specifically for high-frequency operation in power supplies, lighting ballasts, and motor control circuits. The copper windings provide low resistive losses, while the laminated core minimizes eddy current effects, ensuring efficient current regulation and electromagnetic interference suppression. These features are critical in industrial electronics where stable current flow and noise reduction are non-negotiable.
The component is typically wound to achieve inductance values between 100 µH and 10 mH, with saturation currents ranging from 0.5 A to 15 A depending on core size and winding density. Standard operating temperatures range from -40°C to +125°C, consistent with industrial-grade electronic components. The material combination of oxygen-free copper and silicon steel laminations is standard in high-performance choke designs, offering a balance of magnetic permeability and thermal stability.
Buyers in automotive electronics, industrial automation, and telecommunications equipment manufacturing source this choke coil for OEM integration and replacement applications. Packaging is typically bulk in anti-static tubes or trays, suitable for automated assembly lines. Trade terms commonly include FOB Shanghai or CIF destination port, with minimum order quantities negotiable based on coil specifications. Buyers should confirm thermal derating curves and inductance tolerance at operating frequency before procurement.
| Core Material | Laminated iron core |
| Winding Material | Electrolytic copper |
| Inductance Range | 100 µH to 10 mH (typical for this design class) |

| DC Resistance | 0.05 Ω to 2.5 Ω (typical, depends on wire gauge and turns) |
| Frequency Range | 10 kHz to 500 kHz (typical for power supply applications) |
| Insulation Class | Class B (130°C thermal rating, standard for enamel-coated copper) |
| Packaging | Bulk in anti-static tubes or trays (typical for automated assembly) |
| Compliance | Meets RoHS and REACH standards (typical for export-grade electronic components) |
Core Ray Electronics Co., Ltd is based in Xi'an, Shaanxi Province, China, with a registered address at C2406 Nangfang Xingzuo, Zhuque Road Yanta District.

Sourcing Choke coil from Core Ray Electronics Co., Ltd - China Import Guide
Before ordering, verify the core material composition, copper wire gauge, and inductance tolerance at your intended operating frequency and DC bias. Request test reports for saturation current and DC resistance under load. Do not assume performance from generic marketing claims. Confirm that the supplier provides traceable material certifications for copper and laminated steel, even if not ISO certified.
Confirm lead time with the supplier, as custom winding specifications may require 4 to 8 weeks. Incoterms are typically FOB Shanghai or CIF destination port, but payment terms such as T/T in advance or LC at sight should be negotiated. Packaging must be anti-static and moisture-sealed for long-haul shipping. Ask for sample units before bulk shipment to validate physical dimensions and winding quality.
Perform incoming quality checks using a digital LCR meter to verify inductance and DCR against the supplier’s datasheet. Inspect windings for loose turns, damaged insulation, or core misalignment. Request a certificate of conformity for each batch, including lot number, test date, and measured values. For critical applications, consider third-party inspection for dimensional accuracy and solderability.
