◇：Significant Characteristic
* ：If you require another part number please contact with us.
**：Inductance Tolerance 20%
Note 1.： All test data is referenced to 25℃ ambient.
Note 2.： Test Condition:100KHz, 1.0Vrms
Note 3.： Idc : DC current (A) that will cause an approximate △T of 40℃
Note 4.： Isat : DC current (A) that will cause L0 to drop approximately 35%
Note 5.： Operating Temperature Range -55℃ to + 165℃
Note 6.： The part temperature (ambient + temp rise) should not exceed 165℃ under the worst case operating
conditions. Circuit design, component placement, PCB trace size and thickness, airflow and other
cooling provision all affect the part temperature. Part temperature should be verified in the end
application.
Note 7.： The rated current as listed is either the saturation current or the heating current depending on which
value is lower.
Note 8.： Cleaning Process Note
(a) If this power choke is dipped in the cleaning agent, such as toluene, xylene, ketone, and ether
system, there is a possibility that the performance decreases greatly
(b) The high power ultrasonic washing may damage the choke body.
(c) Please contact us if you need the cleaning via the above agents or ultrasonic washing.
