Radial Lead Inductors(Coils)
For Signal Line(Magnetic Shielded)
ELF Series ELF0505
FEATURES
• The ELF series inductors are available in ranging from 0505 to
1010 types.
• Because they are magnetically shielded, these parts can be
used in high-density mounting configurations.
• With a miniature winding construction, these inductors
nonetheless achieve high Q characteristics.
• Available in tape packaging to support automated mounting
machines.
• Terminal platings and internal connecting solder use lead-free
materials.
• This product conforms to the standards that are slated to be
introduced under the RoHS Directive.
APPLICATIONS
Televisions, VCRs, personal computers, and other electronic
equipment.

• The use of reflow soldering is not guaranteed.
• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.
• All specifications are subject to change without notice.
