Features
Top & Bottom Electrode Type for Bonding
GMA Series
This capacitor is suitable for wire bonding mounting by the external electrodes of
Au plating.
Mounting in IC packages is also possible with the upper/lower electrode structure!
Allows for high density mounting.
1
Ideal for bypass applications.
2
Noise can be reduced by eliminating the routing of the wire, and high efficiency can be achieved
with a built-in capacitor in a package, such as IC. Miniaturization of the set is also possible.
Achieved small size and large capacity with a multilayer structure.

Specifications
Excellent in high frequency characteristics.
3
Since the capacitor consists of an upper/lower electrode structure, the current path becomes shorter and lowers
the ESL. Compared with the general purpose GRM series of the same capacity, the impedance of this product
becomes lower at high frequencies.
