About Tianjin Everbloom Technology Co., Ltd. - Ferrite Core Supplier in China

Tianjin Everbloom Technology Co., Ltd. operates from Tianjin, China and currently lists eight active products on its catalogue. The supplier groups its offerings under the broader categories of Agriculture and Air Conditioner Parts, although the detailed items are electronic magnetic components such as ferrite cores and related assemblies. Each product entry references a specific ferrite core form - for example, the “Rohs Ee19 Transformer Ferrite Core Bobbin” and the “T22x14x12.7 Large Size Ferrite Core Toroid”. The catalogue therefore reflects a focus on magnetic cores used in power conversion, amplification, and electromagnetic appliances, all of which are standard parts in air‑conditioning units and related agricultural equipment that employ electronic control systems.

The eight listed items include a mix of bobbin‑type cores, toroidal cores, bar cores and specialized magnetic bars such as the “I Type Ferrite Mnzn Magnetic Bar Core”. Product names indicate material families (Mn‑Zn, Ni‑Zn) and size designations, for instance the “Ft Type Mn‑zn Ferrite Core Magnet” and the “Ei40 Soft Ferrite Core, Ferrite Core Ei 28”. The presence of “Rm4 Pcb Connectors Power Amplifier Core” suggests a core intended for printed‑circuit‑board mounted power amplifiers. Overall, the catalogue provides a concise set of magnetic core components that are commonly integrated into electronic modules for air‑conditioning and other industrial equipment.

Product Range and Specialties of Tianjin Everbloom Technology Co., Ltd.

The supplier’s catalogue comprises transformer bobbins, PCB‑mount power amplifier cores, Mn‑Zn toroidal and bar magnets, as well as soft ferrite cores identified by IEC‑type codes such as Ei40 and Ee. In the wider industry, ferrite cores are classified by composition (Mn‑Zn for low‑frequency, high‑permeability applications; Ni‑Zn for high‑frequency, low‑loss uses) and by shape, which determines inductance and flux density. Typical specifications include initial permeability (µi) ranging from 1 000 to 15 000, loss factor (tan δ) below 0.02 at 100 kHz, and operating temperature limits up to 150 °C. Standard dimensions are expressed in millimetres for outer diameter, inner diameter and height, and tolerance is usually ±0.1 mm for precision parts. Industry standards such as IEC 60147‑2‑2 (magnetic components) and IEC 60384‑14 (inductors) define test methods for permeability, saturation flux density and high‑frequency loss, which buyers commonly reference when evaluating ferrite cores.

Trade and Export Information - Tianjin Everbloom Technology Co., Ltd.

China is a leading exporter of ferrite magnetic components, with most shipments classified under HS chapter 85 for electrical machines and parts. Major import markets include Southeast Asia, Europe and North America, where manufacturers of HVAC systems, automotive electronics and consumer appliances source these cores for power conversion and EMI suppression. Buyers typically require RoHS compliance, REACH registration and material safety data sheets, as ferrite alloys contain manganese, zinc or nickel. Shipping is usually performed in 20‑ft or 40‑ft containers, packed in anti‑static bags inside corrugated boxes to protect against moisture and mechanical shock. Common trade terms are FOB Tianjin or CIF destination ports, allowing buyers to manage freight and insurance according to their logistics preferences.

Sourcing from Tianjin Everbloom Technology Co., Ltd. - Buyer Guidance

When sourcing ferrite cores from this supplier, request a detailed material data sheet that lists composition (e.g., Mn‑Zn 80 % Mn, 20 % Zn), permeability curves across 10 kHz‑1 MHz, saturation flux density and thermal rating. Ask for third‑party test reports that verify RoHS and REACH compliance as well as magnetic loss measurements at the intended operating frequency. Verify the dimensional tolerances and confirm that the core shape (bobbin, toroid, bar) matches the design drawing, and clarify the minimum order quantity, which in the industry often starts at 500‑1 000 pieces per type. Lead time for custom‑size cores from Chinese manufacturers typically ranges from four to six weeks after order confirmation, with packaging in anti‑static poly‑bags and outer cartons suitable for container loading.

What types of ferrite cores does Tianjin Everbloom list in its catalogue?

The catalogue includes transformer bobbin ferrites, PCB‑mount power amplifier cores, Mn‑Zn toroidal cores, soft ferrite cores identified by IEC codes such as Ei40, and Mn‑Zn magnetic bar cores.

Are the listed ferrite cores suitable for high‑frequency applications?

Mn‑Zn ferrites in the catalogue are generally optimized for low to medium frequencies (up to 500 kHz). For high‑frequency uses (above 1 MHz), buyers should confirm whether the core material meets Ni‑Zn specifications or request an alternative grade.

What documentation should a buyer request before placing an order?

Buyers should ask for a material data sheet, magnetic permeability and loss curves, RoHS/REACH compliance certificates, and, if available, a third‑party test report covering saturation flux density and thermal stability.

Is there a standard minimum order quantity for these ferrite cores?

In the ferrite core market, minimum order quantities typically start at 500 pieces per part, but the exact MOQ depends on the specific core size and shape; buyers should confirm the exact figure with the supplier.

What are the common packaging methods for these magnetic components?

Ferrite cores are usually packed in anti‑static poly‑bags, placed inside reinforced cardboard boxes, and then palletised for container loading to protect against moisture and mechanical damage.

Which Incoterms are most frequently used for shipments from Tianjin?

Suppliers from Tianjin often quote FOB Tianjin or CIF destination ports, allowing buyers to arrange freight and insurance according to their preferences.

What industries typically import ferrite cores from China?

Typical importers include HVAC and air‑conditioning manufacturers, automotive electronics producers, consumer appliance makers, and manufacturers of power supplies and amplifiers.

How can a buyer verify the quality of the ferrite cores received?

After receipt, buyers should compare the physical dimensions to the data sheet, perform a permeability test at the intended frequency, and review the supplied RoHS/REACH certificates for compliance.
