DLI V Series capacitors provide improved bypass filtering

Knowles has released the V Series capacitor which can deliver increased broadband rejection in a significantly reduced footprint for bypass capacitor filtering networks.

Released under the DLI brand from Knowles Precision Devices, this capacitor line is built on a compact 30mm by 30mm footprint.This RF signal blocking design tool is intended to solve the needs of 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 is designed to provide broadband rejection in decoupling and filtering applications. If DC lines are not properly decoupled or filtered, RF signals can inject RF power into other components within the system 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. For example, at 10GHz a 10nF V Series component provides over 30dB of rejection, whilst a standard alternative 10nF capacitor would provide only 6dB. 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 and do not sacrifice RoHS compliance in exchange for performance.
