Features
■
The filter’s structure minimizes residual inductance
with a high self resonant frequency, ensuring large
insertion loss in a wide band.
■
The common ground electrode built into the chip
ensures complete grounding of all lines at the
ground on both ends. The filter is designed to
control cross talk.
■
An optimum constant can be selected from the
capacity range of 22-22,000 pF to best suit the
frequency.
■
Solder plated nickel barrier terminations offer good
solderability and resistance to soldering heat.
■
Available lead free/RoHs compliant
Applications
■
Noise reduction for DC lines on computers
■
Computer peripheral equipment
■
Digital TV & VTR
■
Cellular telephones
