Capacitors offer superior bypass filtering, says Knowles

Capacitors in V series deliver increased broadband rejection in a significantly reduced footprint for bypass capacitor filtering networks, says Knowles Precision Devices.

Released under the DLI brand from Knowles Precision Devices, the cost-effective capacitor line is built on a compact 30 x 30 mil footprint. The RF signal blocking design tool is for use by design engineers looking to decouple RF signals from DC bias lines in active circuit designs, such as MMICs, or filter out noise from switching power supplies.

The V series capacitors are designed to provide superior broadband rejection in decoupling and filtering applications, according to Knowles. If DC lines are not properly decoupled or filtered, RF signals can inject RF power into other system components, risking causing severe performance degradation.

The V series DLI capacitors provide as much as twice the rejection when compared with the available alternatives typically used in these applications, says Knowles. For example, at 10GHz a 10nF V series component provides over 30dB of rejection, whilst a standard alternative 10nF capacitor would provide only 6.0dB. The V series capacitors are all designed to provide a minimum of 27dB of broadband rejection out to 40GHz.

In addition, they offer increased voltage ratings compared to alternative devices of a similar size, claims Knowles. They are RoHS- compliant.

Sample kits are available.
