The 197AC25 is the lowest-inductance part in the 197 Series of high frequency reactors, rated 0.075 mH (75 uH) at 25 A DC with wire leads of 6 in minimum. It is intended for high frequency filtering from 60 Hz to 10 kHz where a low inductance must carry 25 A.
The part page lists a self-resonant frequency of 272.3 kHz and a DCR of 18 mOhm. The part drawing, titled Filter Choke, gives test criteria between Lug 1 and Lug 2: inductance without bias of 125 uH ±25%, inductance with 25 ADC bias of 75 uH ±25%, DCR of 7 mOhm ±20%, and a coil-to-core hipot of 2500 V, 60 Hz for 1 second.
Size is 2.00 x 3.25 x 1.60 in (51 x 83 x 41 mm) with a 2.81 in (71 mm) mounting hole pattern. The series table lists 0.875 lbs and the shipping weight is 0.86 lbs (0.39 kg). The drawing label marks 75uH at 25ADC and Made in Canada, and the part is RoHS and REACH compliant. For DC applications, the manufacturer points to the 195-196 Series.
Ideal For
- High frequency filtering from 60 Hz to 10 kHz
