X2Y Integrated Passive Components
X2Y
The Syfer X2Y Integrated Passive Component is a 3
terminal EMI chip device.
When used in balanced line applications, the
revolutionary design provides simultaneous line-to-
line and line-to-ground filtering, using a single ceramic
chip. In this way, differential and common mode
filtering are provided in one device.
For unbalanced applications, it provides ultra low ESL
(equivalent series inductance). Capable of replacing 2
or more conventional devices, it is ideal for balanced
and unbalanced lines, twisted pairs and dc motors, in
automotive, audio, sensor and other applications.
Available in sizes from 0603 to 2220, these filters can
prove invaluable in meeting stringent EMC demands.
Manufactured in the UK by Syfer Technology Limited under licence from X2Y attenuators LLC.

Notes: 1) All dimensions mm (inches).
2) Pad widths less than chip width gives improved mechanical performance.
3) The solder stencil should place 4 discrete solder pads. The un-printed distance between
ground pads is shown as dim E.
4) Insulating the earth track underneath the filters is acceptable and can help avoid
displacement of filter during soldering
but can result in residue entrapment under the chip.
