Chip Array
Steward’s surface mount ferrite chips pr ovide compact, cost effective EMI filtering
for densely packed PCB designs. The small footprint enables placement very close
to troublesome high frequency devices. Our proprietary SMT construction yields
rugged components with impedance versus frequency characteristics superior to
those of similar products.
