Ultra-broadband capacitors for DC blocking over 16 kHz to 40 GHz

March 27, 2014 // By Graham Prophet
GX0S series ultra-broadband capacitors are available with X5R characteristics; they exhibit extremely low insertion loss and excellent return loss

AVX has a new series of ultra broadband capacitors designed to address DC blocking from approx. 16 kHz to 40 GHz. GX0S Series capacitors are packaged in a 0301 case. Featuring X5R characteristics, use them for data communications, transmit and receive optical subassemblies, transimpedance amplifiers, and test equipment.

Electrical specifications for the new GX0S Series are as follows: 0.1 µF capacitance, ±20% tolerance, and 6.3 VDC at 85°C or 4.0 VDC at 125°C operating temperature. Insertion loss for the series will typically fall in the range of 0.4 dB; however, insertion loss at frequencies higher than 40 GHz will be partially dependent on installation parameters.

Using AVX’s precision thin film termination process, GX0S Series Ultra Broadband Capacitors are suited for high volume solder assembly and are available with two termination options; Ni/Sn terminations, which are standard, or Ni/Au terminations, which are wire bondable and can therefore prove particularly useful in bypass applications.
