| X2Y® Filter & Decoupling Capacitors emi low inductance |
Today's circuit designs must maintain Signal 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. |

 |
In circuit 1 the X2Y® component 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. |

When used in circuit 2 configuration the A & B capacitors are connected
in parallel effectively doubling
the apparent capacitance of the device.

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 MLC 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® filter capacitors employ a unique, patented low inductance design featuring two balanced capacitors
that are immune to temperature, voltage and aging performance differences.
These components offer superior decoupling and EMI filtering performance, virtually eliminate parasitics,
and can replace multiple capacitors and inductors saving board space and reducing assembly costs. |
