SMD Inductors(Coils)
For Power Line(Wound, Magnetic Shielded)
VLF-MT Series VLF302510MT
With the VLF302510MT Series, a DC to DC converter with top-
class voltage conversion efficiency for similar size products was
achieved by optimizing the magnetic material and configuration.
These products are optimal for use as choke coils in switching
power supplies such as those in mobile devices requiring space-
saving design.
FEATURES
