Care note 9-1 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. Jun, 2020 CYNTEC CO., LTD. 乾坤科技股份有限公司 DOCUMENT : CMLE105TXXX-040 REVISION : A1 PAGE : 8 OF 8 9-2 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. Jun, 2020
