Chargers And Adapters
ATQ and EE transformers and the bobbins behind them for quick charger and adapter builds.
What Goes Wrong In This Segment
The four problems that come up most often on enquiries from this market.
Height is the binding constraint
A charger housing gives you a few millimetres, and the core shape has to fit inside them.
Electrical values are fixed by the controller
Inductance leakage and turns ratio are set by the reference design, not negotiable.
Hipot has to pass every unit
Primary to secondary isolation is a safety requirement, not a target.
Volumes move fast
A charger programme ramps quickly and a former that cannot be re-tooled becomes the bottleneck.
Typical Applications
- 20 W quick charger transformers on the ATQ1711 geometry
- 65 W quick charger transformers on the ATQ2516 geometry
- EE20 transformers for adapter and auxiliary supplies
- Compact ATQ and EPC formers where total height is limited
How A Project Runs
- You send a drawing a reference design or a part list
- We check it against tooling we already own
- Material pin geometry and electrical values are confirmed in writing
- Samples from an existing tool, or a tool is cut for a new geometry
- Dimensional and electrical checks before shipment

Questions From Chargers And Adapters Buyers
Which parts do you supply into chargers and adapters
Complete transformers with inductance leakage turns ratio and hipot stated per part; ATQ EPC and EE formers for compact charger transformers.
Can you build the whole wound component
Yes. The former the core and the winding can come from one bill of materials and be quoted as a finished part.
What if the core shape I need is not listed
Send the drawing. Tool design and injection moulding are in-house services, so a new geometry is a tooling job.
Do you hold quality certification
ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. All products are RoHS compliant.
How are prices set
Per part and per quantity. Send a part list or a drawing with annual volumes.
Send The Specification
A reference design a drawing or a part list is enough to start. Engineers reply, not a call centre.
