EMI Filtering with X2Y
Many 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. This effectively eliminates the need for a common mode choke*. Several
advantages are gained by two balanced capacitors sharing a single ceramic component body.
Other X2Y Filter Applications
DC-DC converters, power I/O, connectors (RJ45, D-sub), audio/voice/data, CAN, high-speed differential.
Effectively replaces common mode chokes, inductors, ferrites and feedthru capacitors.
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.
Common Mode Choke
9.0 x 6.0 x 5.0 mm
X2Y
2.0 x 1.3 x 1.0 mm
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.
