Feedthru 0805/1206 Capacitors
W2F/W3F Series
GENERAL DESCRIPTION
Available in both a standard 0805 and 1206 size, AVX’s line
of feedthru capacitors are ideal choices for EMI suppres-
sion, broadband I/O filtering, or Vcc power line condition-
ing. The unique construction of a feedthru capacitor pro-
vides low parallel inductance and offers excellent decou-
pling capability for all high di/dt environments and provides
significant noise reduction in digital circuits to <5 GHz. A
large range of capacitor values are available in either NP0
or X7R ceramic dielectrics.

The terminals are connected internally side to side.
Left side and right side are connected and front and
back are connected internally.
For Decoupling, the chip is usually surrounded by
four vias, two for Vcc and two for GND.
For Signal Filtering, the in and out lines need to be
separated on the circuit board.
