PX series provide design engineers with high-reliability solutions for DC blocking in a wide variety of applications – high speed data communications, receiver optical sub-assemblies, transimpedance amplifiers and test equipment. 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. The PX series joins DLI’s OptiCap, which provides DC blocking performance from 16 kHz to 40 GHz.


It has been developed to complement the existing MilliCap and OptiCap broadband devices but in a more shallow profile. Rated at 16 VDC from -55°C to +125°C, the PX series ultra-broadband 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. This smaller package size makes for easier pick and place assembly, whilst not compromising on the bandwidth performance.
