• 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.
APPLICATIONS
Televisions, VCRs, personal computers, and other electronic
equipment.
