New Capacitor Series Offers Broadband Rejection in Decoupling and Filtering Applications

Knowles Precision Devices has introduced the new V Series of capacitors under the DLI brand, that deliver increased broadband rejection in a significantly reduced footprint for bypass capacitor filtering networks. This cost-effective capacitor line is built on a compact 30 mil by 30 mil footprint. This superior RF signal blocking design tool will 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 capacitor family is designed to provide superior 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. These capacitors provide as much as twice the rejection when compared with the available alternatives typically used in these applications. For example, at 10 GHz a 10 nF V Series component provides over 30 dB of rejection, whilst a standard alternative 10 nF capacitor would provide only 6 dB. The V Series capacitors are all designed to provide a minimum of 27 dB of broadband rejection out to 40 GHz.

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. Sample kits are available.
