pad*
U-shaped with central opening extending directly to the outside radius
for easy mounting. By simply straddling a cable or PCB component, a
significant amount of magnetic coupling occurs, between 30%-40% of the
impedance of our fully circumferential styles, depending on configuration.
Excellent for quick, economical applications, tight spaces, electronic
enclosure cable routing, and especially direct mounting over leaded or
surface mount printed circuit board components. Attaches to any surface
with optional adhesive foam base or common electronic adhesives.
