UBC 550 Ultra-Broadband Capacitor

ATC's UBC 550Z, 550U, and 550L series ultra-broadband capacitors have a rugged and compact single-piece, surface-mount, multilayer ceramic construction made of the highest quality, RoHS-compliant materials. They 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.

UBC 550Z Series
The UBC 550Z series ultra-broadband capacitors have an orientation-insensitive 0201 form factor measuring 0.58 mm X 0.3 mm (±0.03 mm). They support operating frequencies spanning 160 KHz with -3 dB roll-off to 70+ GHz at 25°C with no bias applied and with typical insertion loss of <0.4 dB. They are rated for a minimum of 10 nF capacitance, 6.3 V_DC operation from -55°C to +125°C, and 10 V_DC 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).

UBC 550U Series
The UBC 550U series ultra-broadband capacitors have an orientation-sensitive 0201 form factor measuring 0.86 mm X 0.33 mm (±0.05 mm). They support operating frequencies spanning 16 KHz with -3 dB roll-off to 70+ GHz at 25°C with no bias applied and with typical insertion loss of 0.4 dB. They are rated for 100 nF capacitance and 6.3 V_DC 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.

UBC 550L Series
The UBC 550L series ultra-broadband capacitors have an orientation-insensitive 0402 form factor measuring 1.016 mm X 0.508 mm (±0.1 mm). They support operating frequencies spanning 16 KHz with -3 dB roll-off to 70+ GHz at 25°C with no bias applied and with typical insertion loss of <0.5 dB. They are rated for 100 nF capacitance, 16 WVDC from -55°C to +85°C, and 10WVDC from -55°C to +125°C. They also exhibit a ±15% TCC to +85°C at 16WVDC, a ±22% TCC to +125°C at 10WVDC, and 108 Ω or 107 Ω minimum insulation resistance at +25°C or +125°C and working voltage DC (WVDC).
