SMD Wire Wound Chip Inductors - LD Series
LD Series
LD series is the newest open type ferrite wire wound chip inductors.
The wire wound ferrite construction supports lower DCR than other
open type inductors.
Features
RoHS compliant
SMD type wire-wound chip inductor with low DC resistance
Wide inductance range (0.9uH~100uH)
Applications
DSC, DVC, MD, PDA
Portable digital devices
