Transformer And Inductor Manufacturing
Finished transformers and inductors wound and tested to your electrical specification on parts we make ourselves.
What This Service Covers
CB Magnetics does not stop at components. Complete transformers and inductors are built to a customer electrical specification, using bobbins bases cases and cores from our own catalogue. Because the plastic the core and the winding come from one bill of materials, the finished part is quoted and controlled as a single item.
How It Runs
Each stage has an owner and an output you can check.
Electrical specification
Inductance leakage inductance turns ratio and hipot are agreed in writing first.
Mechanical selection
Core shape former and mounting style are chosen or tooled.
Sample build
A first article is built and measured against the specification.
Approval
You approve the sample and the test data before production starts.
Production and test
Winding, assembly, then inductance resistance and insulation checks on the test bench.
Packing and shipment
Packed to your requirement and shipped from Guangdong.
Why It Is Worth Doing This Way
Values are stated not implied
The published transformers list inductance leakage turns ratio and hipot per part.
Quick charger experience
ATQ1711 and ATQ2516 transformers in the catalogue are built for 20 W and 65 W quick chargers.
Low frequency and LAN too
R core toroidal EI low frequency and RJ45 LAN transformers are in the same catalogue.
One bill of materials
Former core and winding from one supplier removes three tolerance stacks.
Questions About This Service
How do I start
Send a drawing or a specification on WhatsApp or by email. It is reviewed against what we already own before anyone quotes.
Who owns the tooling
Tooling terms are agreed in the quotation. Ask for the tooling clause with your quote.
What lead times apply
Lead time is quoted per project because it depends on the tool and the material. It is confirmed with the price rather than published.
Do you handle small volumes
Send the annual quantity with the enquiry and it will be answered honestly rather than after three rounds.
Is the work certified
The plant runs ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 systems and all products are RoHS compliant.
Send The Drawing Or The Specification
Nothing is quoted before your geometry is compared with tooling that already exists. That check is free and it often saves a tool.
