X2Y Filter & Decoupling

The X2Y^®Design - A Capacitive Circuit

XꢀY^®components share many common features with standard multi-layer ceramic capacitors (MLCC) for easy adoption by end-users.

• Same component sizes (0603, 0805, 1206, etc.)

• Same pick and place equipment

• Same dielectric, electrode and termination materials

• Same industry test standards for component reliability

A standard multi-layer ceramic capacitor (MLCC) consists of opposing electrode layers A & B. The XꢀY design adds another set of electrode layers (G) which

effectively surround each existing electrode 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

When used in circuit 1 configuration the XꢀY 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.

Experts agree that balance is the key to a “quiet” circuit. XꢀY® is a balanced circuit device with two equal

halves, tightly matched in both phase and magnitude with respect to ground. 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 XꢀY 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.
