■Features
－Directly connected electrode on ferrite core
－High power, High saturation inductors
－Ideal inductors for DC/DC converters
－With magnetically shielded against radiation
－Available on tape and reel for automatic surface
mounting.
■Applications
－Power Supply for VTRs
－LCD Televisions
－Notebook PCs
－Portable Communication
－DC/DC Converters, etc.
■Characteristics
－Rated DC current: The current when the
inductance becomes 35% lower than its initial
value or the actual current when the
temperature of coil increases to ∆T=40°C. The
smaller one is defined as Rated DC Current.
(Ta=25°C)
－Operating temperature range: -40～85°C
