Ohmite radio frequency plate
chokes have a single-layer
winding designed to avoid
adverse harmonic effects and
prevents breakdown from high
r.f. potentials. Windings are
insulated and protected by a
moisture-proof coating.
• Z-7 type furnished with non-
magnetic mounting bracket.
• Z-14, Z-28 type have wire leads
welded to lug type terminals.
• Z-50, Z-144, Z-235, Z-460 type
have axial wire leads.
