Bobbins bases cores and complete transformers
Magnetic components made to your drawing
One supplier for the plastic the core and the winding. 522 part numbers are published with their material pin geometry and rating so a footprint can be fixed before samples arrive.

What We Make
Transformer bobbins and hardware, bases and cases for toroidal cores, wound inductors and chokes, tape wound cores, and complete transformers.
Who We Serve
Power supply and magnetics designers, and sourcing engineers at contract manufacturers who need one supplier across a whole core series.
What Problem We Solve
Geometry you cannot see until samples arrive, plastics that will not survive your soldering profile, and three suppliers for one wound component.
Why Customers Choose Us
Tooling design moulding assembly and test in one plant, on an ISO 9001 ISO 14001 and ISO 45001 certified system, since 2009.

About CB Magnetics
CB Magnetics is an ISO certified magnetic products manufacturing and integrated solutions company established in 2009. Many of our engineers have more than twenty years of experience in this industry, and that experience goes into reducing cost, holding delivery dates and improving quality on parts that are usually buried inside somebody else power supply.
The range runs from magnetic components through to whole transformers and inductors. All products from CB Magnetics are RoHS compliant.
Questions New Customers Ask
What does CB Magnetics actually make
Transformer bobbins and hardware, bases and cases for toroidal cores and coils, wound inductors and common mode chokes, tape wound core materials, and complete transformers. 522 part numbers are published.
Do you sell components or finished wound parts
Both. You can buy the plastic part alone, the core alone, or a finished transformer or inductor wound and tested to your electrical specification.
Can you make a part that is not in the catalogue
Yes. Custom tooling design and injection moulding is a standing service, so a geometry outside the catalogue is a tooling job rather than a refusal.
Which certifications do you hold
ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. All products from CB Magnetics are RoHS compliant.
Where are you located
Office in Bao'an District Shenzhen and plant in Zengcheng District Guangzhou, Guangdong Province, China.
How do I get a quotation
Send the part numbers and annual quantities by WhatsApp or email. If you have a drawing instead of a part number, send the drawing.
Send A Part Number Or A Drawing
Quotations run off a part number and an annual quantity, or off your drawing if the geometry is new. Either goes straight to an engineer.
