FEATURES
RoHS
Term.W is
RoHS
compliant
& 260°C
compatible
New design features lower DC resistance and
increased current ratings
Electromagnetic shield results in minimal coupling
Epoxy molding provides superior moisture protection
Compatible with flow and reflow soldering
Standard values from 1uH to 1000uH (intermediate
values are available
Mini 1008 size in development
RCD’s MSI Series is ideally suited for telecom, auto, audio,
and power supply line applications. The magnetic shield
reduces cross talk and suppresses radiation. High tempera-
ture internal construction ensures optimum heat durability
compatible with lead-free processes (260°C, 10 Sec.).
