Frequently Asked Questions

Flyback or Resonant: which switching topology is better?

This depends on your specific application requirements.

Flyback converters are simpler but offer lower efficiency at higher power levels.
Resonant converters can achieve higher efficiency but require a more complex design.

Whatever topology is most suitable for your application, we can help you to take full advantage of it.

LLC or LCC: which resonant topology is better?

Similar to the previous question, the choice between LLC and LCC resonant topologies depends on your application.

LLC converters offer good efficiency and voltage regulation, while LCC converters can handle wider input voltage ranges.

Whatever the choice, with our extensive experience in LLC and LCC design – aided by our unique design software – we ensure superior performance and efficiency for your resonant converter.

My design is already optimized. Can you manufacture the transformer according to my design?

Yes, we can manufacture transformers based on your specifications.

However, our engineering team may be able to suggest improvements to further optimize your design for manufacturability, performance and compliance to standards.

I need a few (custom) samples. Can you quickly provide them?

We can quickly provide transformer samples, but for custom components the lead time will depend on the complexity of the design.

To expedite the process, please provide detailed specifications with your request. With comprehensive specifications, it can take 5 business days from the order to the delivery of custom samples.

Where can I find your catalog, or technical data of ITACOIL transformers?

You can find general technical information about ITACOIL transformers on our website.

For detailed specifications on a particular transformer model, or for the full catalog, please contact us.

Where can I buy ITACOIL products?

ITACOIL transformers are available for purchase directly through our company or through our authorized distributors.

Please contact us for more information.

What is the Minimum Order Quantity (MOQ) for a specific ITACOIL product?

Minimum order quantities (MOQ) can vary depending on the specific product.

We cannot supply to private individuals, and generally do not supply very small quantities (except for product samples).

Please contact us for the MOQ of the product you’re interested in.

What is the lead time for a (custom) transformer order?

Lead times for transformers will vary depending on different factors, including but not limited to:

– complexity of the design (especially for custom transformers);
– current production volume;
– plant of production (Europe or Asia);
– material availability (particularly if special materials are required);
– other external factors (e.g. national holidays, possible logistical problems, material shortages etc.).

A preliminary lead time will be estimated after reviewing your inquiry and specifications.

We may offer expedited delivery or production options for an additional fee.
