Idc ( A ) Saturation Current DC Amps. Isat ( A ) K Typical Maximum Typical Maximum Typical Maximum ◇：Significant Characteristic * ：If you require another part number please contact with us. **：Inductance Tolerance 20% Note 1.： All test data is referenced to 25℃ a m b i e n t . 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 30% Note 5.： K : Coefficient of coupling Note 6.： Operating Temperature Range -55℃ to + 165℃ Note 7.： The part temperature (ambient + temp rise) should not exceed 165℃ under the worst case operating conditions. Circuit design, com ponent placement, PCB trace size a n d t h i c k n e s s , a i r f l o w a n d o t h e r cooling provision all affect the part temperature. Part tempera ture should be verified in the end application. Note 8.： The rated current as listed is either the saturation current or the heating current depending on which value is lower. Note 9.： 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 decrease s 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. Current Characteristic 100 0.0 2.0 4.0 6.0 8.0 10.0 12.0 0123456789 1 0 1 1 1 2 1 3 1 4 1 5 1 6 TEMP.
