PILKOR ELECTRONICS CO., LTD.
MULTILAYER FERRITE CHIP INDUCTORS
1608(0603) / 2012(0805) / 3216(1206) Series
Features
1. Internal printed coil structure creates a closed magnetic circuit which acts
as a magnetic shield eliminating crosstalk, thus permitting higher mounting densities.
2. Multilayered ferrite construction provides high reliability.
3. Miniature size : 1608(0603) / 2012(0805) / 3216(1206)
Ⅱ
Applications
Any
general
circuit of portable equipment which compact size and
high mounting densities are required.
