MAGNETICS
Riverside, California – October 16, 2020 – Effective February 27, 2021, Bourns will change the magnet wire

quality enhancement efforts.
The revised magnet wire insulation will be 67 – 80 % thicker than the existing insulation, depending on the part
number. The thicker insulation magnet wire should improve the quality and reliability of these data line chokes.
