X2Y
The X2Y
X2Y
A standard multi-layer ceramic capacitor (MLCC) consists of opposing electrode layers A & B. The X2Y
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.

InAmp Input Filter Example
In this example, a single Johanson X2Y
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.

• Exceptional common mode rejection
• Effects of aging & temperature are equal on both caps
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. Several advantages are
gained by two balanced capacitors sharing a single ceramic component body.
