Thin-Type SMD Choke Coils
(H • SI Series)
{
Outline
The H•SI series is a thin type choke coils realized with a
thickness of 1.8mm to 2 mm.
{
Applications
• Choke coils for LCD display inverters
• Choke coils for various thin-type DC/DC converters
{
Features
• 10µH, 1.1 A in a size of 7.5 6.5 2.0(t)mm (H•SI-0720
series) and 10µH, 2.1 A in a size of 10.2
9.2 2.0(t)mm (H•SI-1020 series)
• High-density mounting is possible thanks to a closed
circuit design.
• The DC bias characteristic at high temperatures is
excellent. (Core curie temperature = approx. 260˚C)
