DIFFERENTIAL MODE
Steward’s
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.
Medium Current
Ferrite Chip Beads
Features:
·Small
footprint
·Excellent
retention under Bias
·Rugged,
monolithic construction
·Superior
impedance vs. frequency characteristics
·Economical ·Broad
range of sizes (from 0603 up to 1812)
·Broad
range of impedance values and current ratings
Applications:
·Filtering
of power input pins and devices using high speed clocks
·Filtering
of low frequency input/output signals of shielded
enclosures
·High
