◇：

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 20%

Note 5.： Operating Temperature Range -55℃ to +155℃

Note 6.： The part temperature (ambient + temp rise) should not exceed 155℃ 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.
