X2Y® Filter & Decoupling Capacitors |
| Today's circuit designs must maintain Signal Integrity amid increasing Electro-Magnetic Compliance
(EMC) requirements, while at the same time lowering system costs.
X2Y® replaces multiple standard passives with a single device, freeing precious board space for additional active components or design miniaturization. |

| Filtering X2Y® Circuit 1 |
Decoupling X2Y® Circuit 2 |
 |
 |
| 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. |
