The X2Y Design - A Capacitive Circuit
X2Y
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 dielectric, electrode and termination materials
Same pick and place equipment
Same industry test standards for component reliability
A standard multi-layer ceramic capacitor (MLCC) consists of opposing electrode layers A & B. The X2Y 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.
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.
Exceptional common mode rejection
Effects of aging & temperature are equal on both caps
Effect of voltage variation eliminated
Matched line-to-ground capacitance
Common Mode Choke Replacement
In this example, a 5 H common mode choke is replaced by an 0805, 1000pF
X2Y component acheiving superior EMI filtering by a component a fraction
of the size and cost.
DC Motor EMI Reduction: A Superior Solution
One X2Y component has successfully replaced 7 discrete filter components
while achieving superior EMI filtering.
InAmp Input Filter Example
In this example, a single Johanson X2Y 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.

X2Y Circuit 1: Filtering
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.
