Transformers
Complete switch mode low frequency toroidal and LAN transformers wound and tested to your electrical specification.
Who This Range Is For
Complete transformers wound and tested to a customer electrical specification: inductance, leakage inductance, turns ratio and hipot are stated per part. The range published here includes ATQ and EE transformers for quick chargers, low frequency and toroidal transformers and RJ45 LAN transformers.
Typical buyers are power supply and magnetics designers fixing a footprint, and sourcing engineers at contract manufacturers who need one supplier to cover a whole series rather than a single size.
Problems It Solves
- Geometry that is only revealed after samples arrive, which blocks the PCB layout.
- A plastic body that will not survive the soldering profile in use.
- Buying the former, the core and the winding from three suppliers and reconciling three tolerances.
- A size change late in a project turning into a new supplier qualification.
Core Advantages
Electrical parameters stated per part
Inductance leakage inductance turns ratio and hipot values are published for the transformers in this range.
Quick charger experience
ATQ1711 and ATQ2516 transformers in this catalogue are built for 20 W and 65 W quick chargers.
Low frequency and toroidal too
R core toroidal and EI low frequency transformers sit alongside the switching types.
LAN magnetics
RJ45 and LAN transformers are part of the same catalogue.

Questions About Transformers
How many parts are published in this range
12 part numbers are listed with their material pin geometry and rating. Parts outside the published list are made from customer drawings.
Do you sell from stock or make to order
Both. Catalogue geometries run from existing tools. New geometries are a tooling job, and tool design and injection moulding are handled in the same plant.
Can you supply the core as well as the plastic part
Yes. Silicon steel amorphous and nanocrystalline cores are part of the same catalogue, and complete wound transformers and inductors can be quoted as a finished component.
What certifications do you hold
ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. All products are RoHS compliant.
How do I ask for a quotation
Send the part numbers and the annual quantity by WhatsApp or email. If you only have a drawing send that instead.
