a) Small Footprint and Low Profile Design :

Footprint : 5.4 x 5.1 mm Typ.

Height : 1.5mm Max.

b) High Power Handling Capability :

Small Copper Loss

Using Large Saturation Induction of

Fe- based metals

c) Flat inductance performance over temperature

based on the high curie temperature of the iron

powder core material.

d) Automatic Mounting in Tape&Reel Package.
