Import Common Mode Choke — Buy in Bulk from Supplier in China

The common mode choke from Beijing Yeke Electronic Materials Co., Ltd. is designed for EMI suppression in power supplies, leveraging iron core materials 1K201 and 1K107 with a saturation magnetic flux density of 1.25T. It delivers high permeability, low loss, and strong anti-electromagnetic interference capability, with a Curie temperature exceeding 570°C and crystallization temperature above 500°C. Its compact design and light weight make it suitable for space-constrained applications.

The iron core’s open structure ensures constant inductance and anti-DC bias capability, ideal for output filter inductors, smoothing inductors, and energy storage inductors in power supplies and energy-saving lamp ballasts. Typical industry standards for such chokes include high initial permeability (often >80,000) and maximum permeability exceeding 600,000, with coercivity below 2 A/m. The material’s low magnetostriction coefficient (<2 × 10⁻⁶) and residual magnetic flux density (0.5 - 0.8T) further enhance performance in high-frequency applications.

Common applications include differential-mode inductance in EMC filters, where its excellent frequency characteristics and temperature stability are critical. Buyers typically source these for industrial power systems, consumer electronics, and lighting solutions. The product is packaged in wooden cases and carton boxes for shipping, with custom iron core specifications available upon request.

Beijing Yeke Electronic Materials Co., Ltd. is based in Shunyi District, Beijing, at 3-4 Zong Er Road, 101309. The company specializes in electronic materials and components, with a focus on magnetic materials and inductors for industrial and consumer applications. Its profile indicates an imported supplier tier, categorized under the harbor trust tier.

The supplier’s response rate is currently listed as 0.00, with no average response time recorded. This suggests buyers should expect delays in inquiries and may need to follow up directly via the provided address. The company’s product range includes customizable iron cores and chokes, with technical specifications tailored to client requests.
