Stewards
surface mount ferrite chips provide 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
superior impedance vs. frequency characteristics.
