Miniature SMD Chip Open-Type Inductors (WB 1008 Type)
• Miniature SMD chip inductors have been designed espe-
cially for the need of today’s high frequency designer. Their
ceramic construction delivers the highest possible SRFs
as well as excellent Q values. The non-magnetic coil form
also assures the utmost in thermal stability, predictability,
and batch consistency.
