Note 1: Customized design is available, please contact us.
Nore 2: All test referenced to 26℃ ambient
Note 3: Inductance tolerance +/- 20%
Note 4: Inductance is measured with Agilent
®
LCR meter 4285A. Test frequency at 1MHz.
Note 5: DC resistance is measured with HIOKI
®
micro-ohm meter RM3542-01.
Note 6: Isat means that DC current will cause a 30% inductance reduction form initial value.
Note 7: Irms means that DC current will cause coil temp. rising to 40℃ whichever is smaller.
