SAFETY REMINDERS
Please pay sufficient attention to the warnings for safe designing when using these products.
REMINDERS
○ The storage period is less than 12 months. Be sure to follow the storage conditions (Temperature: 5 to 40°C, Humidity: 10 to 75% RH
or less).
If the storage period elapses, the soldering of the terminal electrodes may deteriorate.
○ Do not use or store in locations where there are conditions such as gas corrosion (salt, acid, alkali, etc.).
○ Soldering corrections after mounting should be within the range of the conditions determined in the specifications.
If overheated
overheated, a short circuit
circuit, performance deterioration
deterioration, or lifespan shortening may occur
occur.
○ Self heating (temperature increase) occurs when the power is turned ON, so the tolerance should be sufficient for the set thermal
design.
○ Use a wrist band to discharge static electricity in your body through the grounding wire.
○ Do not expose the products to magnets or magnetic fields.
○ Do not use for a purpose outside of the contents regulated in the delivery specifications.
○ The products listed on this catalog 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.

Switching Power Supply Transformers
ECO Series
Conformity to RoHS Directive
Halogen-free
Compatible with lead-free solders
Overview of the ECO Series
Development Concept
The ECO series is compliant with worldwide safety standards∗. It is a pin-compatible, newly developed transformer that can be downsized and thinned.
∗ Applicable as of April 2007: UL/IEC/J 60065 Ver.7 (TV, DVD, STB), UL/IEC/60950 Ver.3 (printer), UL/IEC 60335-1 Ver.4 (home appliance)
■ MATERIAL
Optimum materials and core shape have been developed. No insulation-supporting material is used, and this secures the insulating distance.
While optimizing materials, TDK has further improved its proprietary core shape to develop a new-type ECO core.
TDK has downsized the product considerably in order to securing the necessary creepage distance.
■ MANUFACTURING METHOD
Since the ECO 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
addition, the characteristic variations of the winding wire and creepage tape have largely been removed
removed, stabilizing the transformer's characteristics
characteristics.
■ OPTIMIZATION DESIGN
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) We have prepared an individual specifications request document for the home appliance market.
3) TDK recommends design with a standard core gap (AL-value) for optimization and shorter trial and mass production lead time.
4) Plans for standard winding connection (patterns of recommended pin arrangement and winding structure) are available.
These help to speed up the design process, support automatic winding, and prevent deterioration in quality.
■ ENVIRONMENT
The ECO series is RoHS directive-compliant and halogen-free product.
· Ferrite cores, bobbins, cases, etc. are not sold individually.
· Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based
flame retardants, PBB and PBDE, have not been used, except for exempted ópìr.
· All specifications

are subject to change without notice.

The bobbin is made from phenol with a flame resistance grade of 94V-2 or higher.
*3
The reference output was obtained under conditions where the frequency was 50kHz and creepage distance was 4mm. (See the relevant page for details of each
shape.) The reference output differs depending on the switching device, switching frequency, transformer temperature, conditions, etc. Use this output for reference.
