Micro-Pac™ SMT Power Inductors
Low-Profile / 1.8mm
Description
The Micro-Pac™ product family consists of high-
performance, ferrite-based, low-profile SMT power
inductors. With extremely small footprints, their closed
magnetic field construction ensures low EMI making them
ideal for the energy storage requirements of wireless and
hand-held equipment applications, such as PC cards,
cellular telephones, pagers, GPS, and disk drives.
