Import Ferrite Cores — Buy in Bulk from Supplier in China

Zhejiangtiantong Electronics Co., Ltd supplies ferrite cores designed for power and signal applications. The catalogue lists MnZn ferrite cores rated for switch‑mode power transformers, CRT monitor transformers, pulsed and broadband transformers, and EMI‑resistant uses. It also includes NiZn ferrite cores specifically targeted at EMI‑resistant applications. All cores are described as 1 mm Z type or 2 mm Z type, matching the supplier’s naming convention.

MnZn ferrites typically provide magnetic permeability between 1500 and 2000, making them suitable for low‑frequency power conversion. NiZn ferrites exhibit lower permeability but retain performance up to several megahertz, which is why they are favoured for high‑frequency EMI suppression. Industry practice uses toroidal or E‑core shapes for the listed transformer types, with standard dimensions ranging from 10 mm to 30 mm outer diameter for toroids. The cores are generally rated for operation up to 100 °C and comply with IEC 60233 loss measurement standards.

Buyers such as OEMs of power supplies, display manufacturers, and EMI filter producers typically source these cores in bulk bags of 25 kg. The supplier does not publish minimum order quantities, lead times, or Incoterms, so interested parties should request specific trade terms. Confirming the exact grade, packaging, and any required certifications with Zhejiangtiantong before contract finalisation is recommended.

Zhejiangtiantong Electronics Co., Ltd is located at 99tianzhou Road Shanghai 200233, China. It is classified as an imported tier supplier with a harbor trust tier, indicating the platform’s verification of its trade credentials. The listed response rate is currently 0 %, and no average response time is recorded, suggesting limited recent communication.

The company’s current listing focuses on MnZn and NiZn ferrite cores for a range of transformer and EMI applications. It does not provide details on certifications, production capacity, or pricing, so buyers must obtain those details directly. The supplier’s profile does not mention any export licences or quality management systems.
