Care Note for Use:

(1) Storage Condition:

Temperature 25 to 35℃, Humidity 45 to 60% RH

(2) Use Temperature:

a. Minimum Temperature: -40℃ Ambient temperature of this product.

b. Maximum Temperature: +125℃ The value of temperature including ambient and temperature rise of

this product.

c. Reliability test temperature range from -40 ~ +125℃

d. However, this is not meant as temperature grade guarantee for UL.

(3) Model:

When this product was used in a similar or as new product to the original one, sometimes it might be

unable to satisfy the specifications due to difference in condition of usage.

(4) Drop:

If this product suffered mechanical stress such as drop, characteristics may become poor ( due to damage

on coil / bobbin / ferrite … etc. )

Never use such stressed product.

Care Note for Safety:

(1) Provision to Abnormal Condition:

This product itself does not have any protective function in abnormal condition such as overload, short-

circuit and open-circuit conditions, etc.

Therefore, it shall be confirmed from the end product that there is no risk of smoking, fire, dielectric

withstand voltage insulation resistance, etc. in abnormal conditions to provide protective devices and /or

protection circuit in the end product.

(2) Temperature Rise:

Temperature rise on this product depends on the installation condition on end products.

It shall be confirmed on the actual end product that temperature rise of this product is within the specified

temperature class limit.

(3) Dielectric Strength:

Dielectric withstanding test with higher voltage than specific value will damage insulating material and

shorten its life.

(4) Water:

This product must not be used in wet condition resulted from water, coffee or any liquid contact because

insulation strength becomes very low under such condition.

(5) Potting:

If this product is potted in some compound, coating material of magnet wire might be occasionally

damaged. Please ask us if you intend to pot this product.

(6) Detergent:

Please consult AiT Semi immediately once under such circumstances because product reliability
