* : If you require another part number please contact with cyntec.
Note 1 : All test data is referenced to 25 ambient.
Note 2 : Idc : DC current (A) that will cause an approximate T of 40
Note 3 : Isat : DC current (A) that will cause Lo to drop approximately 20%
Note 4 :Operating Temperature Range -55 to + 125
Note 5: The part temperature (ambient + temp rise ) should not exceed 125 under worse case
operating conditions. Circuit design , component placement, PWB trace size and thickness,
airflow and other cooling provision all affect the part temperature. Part temperature should be
verified in the end application.

10. Care note
10-1 Care note for Use
(1) Storage Condition :
Temperature 25 to 35, Humidity 45 to 85% RH
(2) Use Temperature :
a. Minimum Temperature : -55 Ambient temperature of power choke coil.
b. Maximum Temperature : +125 The value of temperature including ambient of the
transformer and temperature rise of power choke coil.
c. There is not a problem from -55 ~ +125 in a reliability test.
d. However, this is not meant a temperature grade guarantee of UL.
(3) Model :
When this power choke coil was used in a similar or new product to the original one,
sometimes it might be unable to satisfy the specifications due to difference of condition
of usage.
(4) Drop :
If the power choke coil suffered mechanical stress such as drop, characteristics may
become poor ( due to damage on coil bobbin, etc. ).
Never use such stressed power choke coil.

10-2 Care note for Safety
(1) Provision to Abnormal Condition
This power choke coil 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 as 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 of power choke coil depends on the installation condition on end
products.
It shall be confirmed on the actual end product that temperature rise of power choke
coil is in the limit of specified temperature class.
(3) Dielectric Strength
Dielectric withstanding test with higher voltage than specific value will damage insulating
material and shorten its life.
(4) Water
This power choke coil must not be used in wet condition by water, coffee or any liquid
because insulation strength becomes very low on the condition.
(5) Potting
If this power choke coil is potted in some compound, coating material of magnet wire
might be occasionally damaged. Please ask us if you intend to pot this power choke coil.
(6) Detergent
Please consult our company once in case of this because the confirmation of reliability
etc. is needed when the washing medicine is used for the power choke coil.
