Two Sections Bobbin Type(For High Frequency) UF Series
FEATURES
• This series uses a Mn-Zn ferrite core and yet it offers excellent
noise suppression into the high frequencies due to its low
distributed inductance construction based on a single layer
winding.
• This compact filters's inductance has been improved by as much
as 50% compared to exsting products of compareble size while
its hight profile has been reduced by approximately 30%.
