Ultra-broadband capacitors provide reliable and repeatable performance

KYOCERA AVX offers UBC 550 Series ultra-broadband capacitors that offer reliable, repeatable performance from 16KHz to 70GHz+ in the ultra-broadband microwave and millimetre-wave RF applications with strict operating conditions. The UBC 550Z, 550U, and 550L Series ultra-broadband capacitors offer a rugged and compact single-piece, surface-mount, multilayer ceramic construction created from the highest quality, RoHS-compliant materials and displaying ultra-low insertion loss, flat frequency response, superior return loss, and high unit-to-unit repeatability. These characteristics make the series excellent for DC blocking, coupling, bypassing, and feedback applications within optoelectronics, trans-impedance amplifiers, broadband test equipment, SONET, ROSA, and TOSA, high-speed data networks, and other ultra-broadband microwave and millimetre-wave RF applications.

Also, all three of the series (UBC 550Z, 550L, and 550U) are rated for dielectric withstanding voltages of 250% WVDC for up to five seconds and are provided in rugged SMT packages with standard tin or optional gold-over-nickel terminations.

“We are proud to introduce our series of ultra-broadband capacitors, designed and manufactured to satisfy the stringent performance requirements of a range of microwave and millimetre-wave RF applications with frequencies spanning 16KHz to 70GHz+,” said Alexander Hall, RF/Microwave field applications engineer at AVX.

“Our UBC 550 Series ultra-broadband capacitors display ultra-low insertion loss, excellent return loss, flat frequency response, and high unit-to-unit repeatability and – unlike competing two-piece solutions – have a compact, single-piece, surface-mount multilayer ceramic construction that’s made of the highest quality materials, ruggedised for reliability, fully compatible with automated assembly processes, and proven to deliver superior reliability and performance in DC blocking, coupling, bypassing, and feedback applications within ultra-broadband applications including optical communications systems and other high-speed networking equipment.”
