Broadband DC blocking capacitors

9 November 2016 Passive Components

Knowles brand DLI is establishing a range of broadband blocking components under the ‘Xtreme Broadband Blocking Components’ umbrella. Existing parts like Opti-Cap, Milli-Cap, MLC Broadband Blocks and RF Blocking Networks will be included, as well as new ones - the first of which is the PX range for DC blocking applications up to 40 GHz.

The PX series provides design engineers with high-reliability solutions for DC blocking in a wide variety of applications - semiconductor data communications, The PX series provides a surface-mount, low-cost solution that exhibits ultra broadband performance, extremely low insertion loss, low frequency stability and excellent return loss across the wide bandwidth.

It has been developed to complement the existing MilliCap and OptiCap broadband devices but in a more shallow profile. Rated at 16 V d.c. from -55°C to +125°C, the capacitors initially feature a 0402 case size and X7R dielectric characteristics at 100 nF; a 0201 sized version, currently available in MiliCap and OptiCap series, will follow shortly.
