X2Y® for Today’s Circuits
Circuit designers today are challenged with maintaining Signal and Power Integrity amid increasing Electro-Magnetic Compliance (EMC) requirements,
®
®
while at the same time lowering system costs. X2Y Technology is an enabler to this end, providing a quantum leap in circuit performance. X2Y
replaces multiple standard passives and Integrated Passive Components with a single device, freeing precious board space for additional active
®
components or design miniaturization. In short, X2Y gives end-users the cost advantage they need to compete in today’s market.
X2Y® Technology Overview
®
X2Y components share many common traits with conventional multi-layer ceramic capacitors (MLCC) to facilitate adoption by end-users into their
manufacturing processes
• Same component sizes (0603, 0805, 1206, etc.)
• Same pick and place equipment
• Same voltage ratings
• Same dielectric, electrode and termination materials
• Same industry test standards for component reliability
The X2Y® design - A Capacitive Circuit
A standard bypass capacitor has opposing electrode layers stacked inside. An X2Y adds another set of electrode layers to effectively surround each
®
existing electrode within the stack of a two-terminal capacitor. The only external difference is two additional side terminations, creating a four-terminal
capacitive circuit, which allows circuit designers a multitude of attachment options.

X2Y® Circuit 1: Filtering
X2Y® Circuit 2: Decoupling
When used in circuit 2 configuration A & B capacitors are placed
in parallel effectively doubling the apparent capacitance while
maintaining an ultra-low inductance.
®
When used in circuit 1 configuration the X2Y filter capacitor is
connected across two signal lines. Differential mode noise is filtered
to ground by the two Y capacitors, A & B. Common mode noise is
cancelled within the device.

EMI Filtering with X2Y®
Many experts agree that balance is the key to a “quiet” circuit. X2Y® is a balanced circuit device with two equal halves, tightly matched
in both phase and magnitude with respect to ground. This effectively eliminates the need for a common mode choke*. Several
advantages are gained by two balanced capacitors sharing a single ceramic component body.
• Exceptional common mode rejection
• Effect of voltage variation eliminated
• Matched line-to-ground capacitance
• Effects of aging & temperature are equal on both caps
InAmp Input Filter Example
In this example, a single Johanson X2Y component was used to filter noise at the input of a DC
instrumentation amplifier. This reduced component count by 3-to-1 and costs by over 70% vs.
conventional filter components that included 1% film Y-capacitors.

Decoupling with X2Y®
The low inductance advantages of the X2Y® Capacitor Circuit enables high-performance bypass networks at reduced system cost.
• Low ESL (device only and mounted)
• Broadband performance
• Lower via count, improves routing
• Reduces component count
• Lowers placement cost
• Effective on PCB or package
Component Performance
®
The X2Y has short, multiple and opposing current paths
resulting in lower device inductance.

OPTIMIZING X2Y PERFORMANCE WITH
P
ROPER
ATTACHMENT
TECHNIQUES
X2Y® capacitors excel in low inductance performance for a myriad of appli-
cations including EMI/RFI filtering, power supply bypass / decoupling. How
the capacitor is attached to the application PCB is every bit as important as
the capacitor itself. Proper attention to pad layout and via placement insures
superior device performance. Poor PCB layouts squander performance, requir-
ing more capacitors, and more vias to do the same job. Figure 1 compares the
X2Y® recommended layout against a poor layout. Because of its long extents
from device terminals to vias, and the wide via separation, the poor layout
shown performs badly. It exhibits approximately 200% L1 inductance, and
150% L2 inductance compared to recommended X2Y® layouts.
