CYNTEC CO., LTD. 乾坤科技股份有限公司 Oct., 2019 DOCUMENT : SDER041H-000 REVISION : B3 PAGE : 3 OF 6 Specifications Part Number Inductance ( H ) @ (0A) Rdc ( m) Heat Rating Current DC Amps. Idc ( A ) Saturation Current DC Amps. Isat ( A ) Typical Maximum Typical Maximum Typical Maximum *：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.： Operating Temperature Range -55℃ to + 125 ℃ Note 6.： The part temperature (ambient + temp rise) should not exceed 12 5℃ under the worst case operating conditions. Circuit design, com ponent 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.
