When designing the board, ensure a distance from the transformer in accordance with the applicable safety standards.
The product is not quakeproof structure. Accordingly please do not add vibration and a shock to it.
The product produces possibility to lose a function.
Attention on the handling
Please do not use it when you let a product drop.
The product produces possibility to lose a function.
Be careful not to get injured because the tip of the terminal is sharpened by soldering.
For storage, avoid dust, dust, fog, water droplets and direct sunlight.
There is fear to cause false movement of machinery.
Do not use or store in an environment with gas corrosion (salt, acid, alkali, etc.).
The product produces possibility to lose a function.
When mounting, do not apply excessive force to the product with metal tools or the like.
The product produces possibility to lose a function.
Attention
The structure and number of turns (magnetic mounting) are determined in consideration of safety standards, power supply voltage, circuit drive
conditions (drive frequency and maximum ON period), etc., so avoid using them outside the design conditions.
There are destruction of a circuit part and fear of ignition.
The operating temperature and humidity ranges are determined in consideration of the characteristics of the components and the self-temperature rise,
so please avoid using in a range exceeding this range.
There is a risk of burning or ignition.
Avoid using it in an environment where dust and dirt are likely to adhere.
There is a risk of cause a fire.
The products listed on this specification sheet are intended for use in general electronic equipment (AV equipment, telecommunications equipment,
home appliances, amusement equipment, computer equipment, personal equipment, office equipment, measurement equipment, industrial robots)
under a normal operation and use condition.
The products are not designed or warranted to meet the requirements of the applications listed below, whose performance and/or quality require a more
stringent level of safety or reliability, or whose failure, malfunction or trouble could cause serious damage to society, person or property.
Please note that we are not responsible for any damages caused by exceeding the scope and conditions of this specification or by using it for a specific
purpose
If you exceed the scope and conditions of this specification, or plan to use it for a specific purpose, please contact us in advance.

Choke Coils for PFC
Pin terminal type
Development Concept of the PFC series
This is a power - factor improvement circuit for choke coils for smaller, thinner and narrow floor space in recent years electronic
equipment.
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 the original core shape for PFC has been developed.
The product line-up has been expanded to cater for various types of electronic devices that need to become smaller, thinner and narrow
floor space.
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.
Please be sure to request delivery specifications that provide further details on the features and specifications of the products for proper and safe use.
Please note that the contents may change without any prior notice due to reasons such as upgrading.
