AVX Corporation, a manufacturer and supplier of advanced electronic components and interconnect, sensor, control, and antenna solutions, has released new UBC 550 Series Ultra-Broadband Capacitors, designed to deliver reliable, repeatable performance from 16 kHz to 70+ GHz in the ultra-broadband microwave and millimeter-wave RF applications with stringent operating requirements.
The new UBC 550Z, 550U, and 550L Series have a rugged and compact single-piece, surface-mount, multilayer ceramic construction made of the highest quality, RoHS-compliant materials and exhibit ultra-low insertion loss, excellent return loss, flat frequency response, and high unit-to-unit repeatability. These characteristics make the series ideally suited for use in DC blocking, coupling, bypassing, and feedback applications within optoelectronics, high-speed data networks, transimpedance amplifiers, broadband test equipment, synchronous optical networks (SONET), transmit and receive optical subassemblies (TOSA and ROSA), and other ultra-broadband microwave and millimeter-wave RF applications.
The new UBC 550Z Series have an orientation-insensitive 0201 form factor measuring 0.58 X 0.3 mm (±0.03mm) and support operating frequencies spanning 160 kHz with -3 dB roll-off to 70+ GHz at 25°C with no bias applied and with a typical insertion loss of <0.4 dB. They are rated for a minimum of 10 nF capacitance, 6.3 VDC operation from -55°C to +125°C, and 10 VDC operation from -55°C to +85°C. They also exhibit a ±22% temperature coefficient of capacitance (TCC) to +125°C, a ±15% TCC to +85°C, and 108 Ω or 107 Ω minimum insulation resistance at +25°C or +125°C and working voltage DC (WVDC).
The new UBC 550U Series have an orientation-sensitive 0201 form factor measuring 0.86 X 0.33 mm (±0.05mm) and support operating frequencies spanning 16 kHz with -3 dB roll-off to 70+ GHz at 25°C with no bias applied and with a typical insertion loss of 0.4 dB. They are rated for 100 nF capacitance and 6.3 VDC operation from -55°C to +85°C, and they exhibit a ±15% TCC over the rated temperature range and 1010 Ω or 109 Ω minimum insulation resistance at +25°C or +85°C and rated voltage.
The new UBC 550L Series have an orientation-insensitive 0402 form factor measuring 1.016 X 0.508 mm (±0.1mm) and support operating frequencies spanning 16 kHz with -3 dB roll-off to 70+ GHz at 25°C with no bias applied and with a typical insertion loss of <0.5 dB. They are rated for 100 nF capacitance, 16 WVDC from -55°C to +85°C, and 10 WVDC from -55°C to +125°C. They also exhibit a ±15% TCC to +85°C at 16 WVDC, a ±22% TCC to +125°C at 10 WVDC, and 108 Ω or 107 Ω minimum insulation resistance at +25°C or +125°C and working voltage DC (WVDC).
In addition, all three UBC 550 Series (UBC 550Z, 550L, and 550U) are rated for dielectric withstanding voltages of 250% WVDC for up to five seconds, are available in rugged SMT packages with standard tin- or optional gold-over-nickel terminations, and are packaged on tape and reel in quantities of 500 or 1,000 pieces for compatibility with high-speed, automated, pick-and-place manufacturing equipment.
Alexander Hall, RF/Microwave field applications engineer at AVX said that they are proud to introduce their newest series of ultra-broadband capacitors designed and manufactured to satisfy the stringent performance requirements of a range of microwave millimeter-wave RF applications with frequencies spanning 16 kHz to 70+ GHz. He further stated that their new UBC 550 Series ultra-broadband capacitors exhibit ultra-low insertion loss, excellent return loss, flat frequency response, and high unit-to-unit repeatability and — unlike competing for two-piece solutions — have a compact, single-piece, surface-mount multilayer ceramic construction that’s made of the highest quality materials, ruggedized 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.
UBC 550 Series Ultra-Broadband Capacitors from AVX Corporation are immediately available as eight different part numbers: 550Z103PTT and 550Z103PCAT, 550U104MTT and 550U104MCA, and 550L104KTT, 550L104KCAT, 550L104VTT, and 550L104VCAT. The standard lead-time for the series is currently 24 weeks.
