Grewin Toroidal Core Chokes Inductor
Grewin Toroidal Core Chokes Inductor is a line of power‑line filtering components produced by Tianjin Grewin Technology Co., Ltd. The devices comply with ISO 9001:2015, CE, SGS and IEC reporting standards and have also attained RoHS certification. They operate across a frequency range of 50 Hz to 500 kHz and tolerate temperatures from - 40 °C to +105 °C, making them suitable for a broad spectrum of industrial environments.
The inductors feature a nylon‑protected toroidal core with separated windings to minimise inter‑winding capacitance and a single‑layer winding for high common‑mode impedance. Typical toroidal cores of this family use ferrite material, with standard inductance values ranging from 10 µH to 10 mH and current ratings of 0.5 A to 5 A, although exact figures depend on the selected size. Mounting options include vertical or horizontal configurations, allowing flexibility in PCB layout design.
These chokes are commonly applied in power‑line filtering, EMI/RFI suppression for switch‑mode power supplies and other high‑frequency noise‑reduction tasks. The supplier notes that flexible minimum order quantities are possible and that packaging is designed to protect the windings during shipment. Shipping terms such as FOB or CIF are available, but lead‑time and payment conditions must be confirmed with the manufacturer.

Sourcing Grewin Toroidal Core Chokes Inductor from Tianjin Grewin Technology Co., Ltd. - China Import Guide
Importers should first obtain the latest certification copies and, if possible, a sample unit to verify inductance, tolerance and physical dimensions against the design requirements. Confirm that the core material and winding configuration meet the intended frequency and current specifications for your application.
Shipping terms are offered under FOB or CIF; clarify the preferred incoterm, approximate freight cost based on the unit weight and volume, and the expected lead‑time, which is not disclosed in the listing. Payment methods such as T/T, L/C or escrow should be negotiated and documented in the purchase agreement.
Arrange a pre‑shipment inspection by a qualified third‑party testing house to check for dimensional accuracy, inductance tolerance, insulation resistance and RoHS compliance. Request a final test report that includes the measured inductance, DC resistance and any relevant IEC test results before releasing payment.
