SAMWHA ELECTRONICS
SAMWHA ELECTRONICS
Description
Introduction
This shape gives very strong benefit when required height limit and power density. The most ideal shape for this requirement among ferrite cores.
Features
Comparing to other E shapes, its center leg is designed low and wide so that it obtain same volume but extreamly lower thickness.
Applications
It is sutable for low limit application such as LCD, LED divice.
