The 197AB25 is a high frequency reactor rated 0.15 mH at 25 A DC with screw terminals. It has the highest self-resonant frequency in the 197 Series table, 1452.0 kHz, and is intended for high frequency filtering from 60 Hz to 10 kHz.
The drawing lists typical inductance with bias of 0.150 mH ±15% at 25 ADC, impedance at SRF of 4.50K ohms, ripple current of 20% peak-to-peak and DCR of 10 mOhm ±15% at 20°C, the lowest DCR in the series table. Dielectric strength is 2500 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. The label reads 0.15mH ±15%, 25A DC, 60Hz to 10kHz @ 10% ADC.
Construction uses an aluminum base, stainless steel band and open-style terminals. Size is 3.31 x 3.40 x 2.50 in (84 x 86 x 64 mm), with a 2.50 x 2.00 in (64 x 51 mm) mounting hole pattern. The drawing and series table give 2.5 lbs and the shipping weight is 2 lbs (0.91 kg). Made in Canada per the label; RoHS and REACH compliant.
