- 2000 V RMS dielectric strength
The 197AB20 is a high frequency reactor rated 0.12 mH at 20 A DC, packaged in a universal channel frame with insulated flexible leads of 6 in minimum. It is designed for high frequency filtering from 60 Hz to 10 kHz where a light, lead-wired inductor is preferred.
Typical drawing data: inductance with bias 0.120 mH ±15% at 20 ADC, self-resonant frequency 1246.4 kHz, impedance at SRF 3.54K ohms, ripple current 20% peak-to-peak and DCR 25 mOhm ±15% at 20°C. Dielectric strength is 2000 V RMS and temperature range is -40 to 105C. The core is high permeability carbonyl iron powder, described as ideal for applications below 50 kHz. Performance graphs for this part were taken at 2.0 V AC drive.
Size is 2.00 x 3.25 x 1.65 in (51 x 83 x 42 mm), with a 2.81 in (71 mm) mounting hole pattern and dimensional tolerance of ±0.063 in unless otherwise specified. The drawing weight is 14 oz, the series table 0.875 lbs, and the shipping weight 0.86 lbs (0.39 kg). The label states Made in Canada; RoHS and REACH compliant.
Ideal For
- High frequency filtering from 60 Hz to 10 kHz
