Development Concept of the PFC Series

This small and thin PFC choke coil utilizes a power factor-improving circuit, which is suitable for the smaller and thinner electronic devices

of recent years.

MATERIAL

Thanks to the development of an optimized core shape and materials, the choke coil has DC superimposition characteristics suitable for

the design of various types of electronic devices.

Optimized materials have been selected, and at the same time a small and thin PFC core with TDK's proprietary core shape has been

developed.

The product line-up has been expanded to cater for various types of electronic devices that need to become smaller and thinner.

MANUFACTURING METHOD

Since the PFC Series supports automatic winding, the product is of a high quality and can be manufactured stably.

It is designed to support automatic winding, which enables a remarkable reduction in the loss generated to achieve a proficient in

manual winding until stable production.

In addition, the characteristic variations of the winding wire and creepage tape have largely been removed, stabilizing the transformer's

characteristics.

OPTIMIZATION DESIGN

While the existing line-up of standard products remains available, new products can also be manufactured to meet customers' requests.

Using design tools developed with TDK's comprehensive know-how, high-precision design has been achieved in a short period of time.

1) For optimization design and high-quality stable production, customers can use a specification request form.

If you provide the necessary information in the form, you will receive the optimization design in a short time.

2) TDK recommends design with a standard core gap (AL-value) for optimization and shorter trial and mass production lead time.

ENVIRONMENT

The PFC series is RoHS directive-compliant product.

• All specifications are subject to change without notice.
