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.
