Back to the X2Y Technology Page

When used in circuit 2 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 X2Y® Capacitor Circuit enables high-performance bypass networks at reduced system cost.

Low ESL (device only and mounted)
Broadband performance
Effective on PCB or package

Lower via count, improves routing
Reduces component count
Lowers placement cost

COMPONENT PERFORMANCE
The X2Y® has short, multiple and opposing current paths resulting in lower device inductance.

SYSTEM PERFORMANCE

1:5 MLCC Replacement Example

X2Y’s® proven technology enables endusers 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.
