Decoupling with X2Y®
The low inductance advantages of the X2Y® Capacitor Circuit enables high-performance bypass networks at reduced system cost.
• Low ESL (device only and mounted)
• Broadband performance
• Lower via count, improves routing
• Reduces component count
• Lowers placement cost
• Effective on PCB or package
Component Performance
®
The X2Y has short, multiple and opposing current paths
resulting in lower device inductance.
Mounted Performance
Mutual coupling from
opposing polarity vias
lowers inductance when
mounted on a PCB.

X2Y’s
proven technology enables end-
users to use one X2Y capacitor to replace
five conventional MLCCs in a typical high
performance IC bypass design. Vias are nearly
cut in half, board space is reduced and savings
are in dollars per PCB.
