Compact Single-Piece UBC 550 Series Ultra-Broadband Capacitors for Ultra-Broadband Microwave and Millimetre-Wave RF Applications

AVX Corporation has introduced a new UBC 550 series of ultra-broadband capacitors for offering reliable and repeatable performance from 16KHz to 70+GHz. The UBC 550Z, 550U, and 550L Series ultra-broadband capacitors are offered in a compact single-piece, surface-mount, multilayer ceramic construction and delivers ultra-low insertion loss, excellent return loss, flat frequency response, and high unit-to-unit repeatability.

The UBC 550 series ultra-broadband capacitors can be used in ultra-broadband microwave and millimetre-wave RF applications including DC blocking, coupling, bypassing, and feedback applications within optoelectronics, high-speed data networks, trans-impedance amplifiers, broadband test equipment, synchronous optical networks (SONET) and transmit and receive optical subassemblies (TOSA and ROSA).

The UBC 550U series capacitors exhibit a ±15% TCC over the rated temperature range and 1010Ω or 109Ω minimum insulation resistance at +25°C or +85°C and rated voltage. Whereas, the UBC550Z and UBC 550L Series exhibit a ±15% TCC to +85°C at 16WVDC, a ±22% TCC to +125°C at 10WVDC, and 108Ω or 107Ω minimum insulation resistance at +25°C or +125°C and working voltage DC (WVDC). All the devices in the UBC 550 series are designed for withstanding voltages of 250% WVDC for up to five seconds in the rugged SMT packages.
