SMD Inductors(Coils)
For Power Line(Wound, Magnetic Shielded)
Conformity to RoHS Directive
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
• Miniature size
Mount area: 3.0×2.5mm
Low profile: 1.0mm max. height
• Generic use for portable DC to DC converter line.
• High magnetic shield construction should actualize high resolu-
tion for EMC protection.
• The products contain no lead and also support lead-free
soldering.
• The products is halogen-free.
• It is a product conforming to RoHS directive.
APPLICATIONS
Smartphones, cellular phones, DSCs, DVCs, HDDs, LCD displays,
compact power supply modules, etc.

HANDLING AND PRECAUTIONS
• Before soldering, be sure to preheat components.
The preheating temperature should be set so that the
temperature difference between the solder temperature and
product temperature does not exceed 150°C.
• When hand soldering, apply the soldering iron to the printed
circuit board only. Temperature of the iron tip should not exceed
350°C. Soldering time should not exceed 3 seconds.
