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.

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.

X2Y® Circuit 2: Decoupling
When used in circuit ꢀ configuration, A & B capacitors are placed in parallel effectively doubling the apparent capacitance while maintaining an ultra-low
inductance. The low inductance advantages of the XꢀY® Capacitor Circuit enables high-performance bypass networks at reduced system cost.

capacitors
XꢀY® 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.

XꢀY® capacitors excel in low inductance performance for a myriad of applications including EMI/RFI filtering, power supply bypass
/ decoupling. How the capacitor is attached to the application PCB is every bit as important as the capacitor itself. Proper attention
to pad layout and via placement insures superior device performance. Poor PCB layouts squander performance, requiring more
capacitors, and more vias to do the same job. Figure 1 compares the XꢀY® recommended layout against a poor layout. Because
of its long extents from device terminals to vias, and the wide via separation, the poor layout shown performs badly. It exhibits
approximately ꢀ00% L1 inductance, and 150% Lꢀ inductance compared to recommended XꢀY layouts.
For further details on via placement and it’s effect on mounted inductance, please refer to XꢀY Attenuators, LLC. application note
