Note 1: All dimensions mm (inches).
Note 2: Pad widths less than chip width gives improved mechanical performance.
Note 3: Insulating the earth track underneath the filters is acceptable and can help avoid displacement of filter
during soldering.
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.
Advantages
Replaces 2 or 3 capacitors with one device
Ultra low inductance due to cancellation effect
For balanced lines:
Matched capacitance line to ground on both lines
Differential and common mode attenuation
Effects of temperature and voltage variation eliminated
Effect of ageing equal on both lines
High current capability
Applications
Single ended/unbalanced lines
Balanced lines and twisted pairs
EMI Suppression on dc motors
Sensor/transducer applications

Surface mount EMI filters - X2Y Integrated Passive Components
The internal structure furnishes a reduced inductance when
compared to that of a conventional capacitor. This is a result
of the novel internal electrode structure which inherently
reduces the inductance by the cancellation effect of opposing
currents in close proximity. The capacitance line to ground
(common mode) is closely matched due to the symmetry
within the design. As the device includes line to ground
capacitance for both lines, any temperature, ageing and
voltage effects will have an equal influence on both lines
therefore maintaining balanced decoupling.
Because the part acts as a de-coupling device, the current
limitations of a standard 3 terminal chip do not apply. The
single line 3 terminal feedthrough chip carries the signal
current through the very thin feedthrough electrodes within
the device which have limited dc resistance and so can cause
excessive heating, hence the maximum permissible current
is often limited to around 300mA for a 1206 device. The
Integrated Passive Component is in by-pass across two lines
and so is unaffected by high signal currents.
The table below offers a comparison of de-coupling devices
and demonstrates how the Integrated Passive Component
extends the options for EMC circuit protection.
