APPLICATION INFORMATION ON DISCOIDAL
LOWEST CAPACITANCE IMPEDANCES TO GROUND
A discoidal MLC capacitor has very low impedance associated with its ground path
since the signal is presented with a multi-directional path. These electrode paths,
which can be as many as 100, allow for low ESR and ESL which are the major ele-
ments in impedance at high frequencies.
The assembled discoidal element or feed-thru allows signal to be fed in through a
chassis or bulkhead, conditioned as it passes through the discoidal, and isolated by
the chassis and discoidal from the original signal. An example of this application
would be in an AFT circuit where the AC noise signal would be required to be
stripped from the DC control signal. Other applications include single line EMI/RFI
suppression, L-C filter construction, and coaxial shield bypass filtering.
The shape of the discoidal lends itself to filter construction. The short length allows
compact construction where L-C construction is desired.
The size freedom associated with this element allows almost any inside/
outside diameter combination. By allowing the inside diameter to equal
the center insulator diameter of a coaxial signal line and special termination tech-
niques, this device will allow bypass filtering of a floating shield to ground.
Discoidal capacitors are available in three temperature coefficients (C0G, X7R, Z5U)
and a variety of sizes, the most standard of which appear in this catalog.
