Smoltek can today show a capacitor prototype that is only a few micrometres high and together with the necessary substrate (component carrier) barely reaches 40 micrometres in total height. This at the same time as one can show a capacitance density of 500nF/mm2 (nanofarad per square millimetre), an equivalent series resistance below 10 mΩ (milliohm) and an internal inductance below 15 pH (picohenry).

The DG8SAQ VNWA 3 is a 2-port VNA. The early model, the 3E, is capable of only an S11 and S21 measurement. This means that while it has 2-ports, it only measures in the forward direction. The latest model, the VNWA 3SE, is capable of fully automatic 2-port measurements. While they can both be calibrated with traditional SOLT standards, SDR Kits recently introduced a recall unit, the Magi-Cal, which is compatible with both instruments.

Stackpole releases HCSM2818 high current shunt chip resistors with a 5W power rating. Modern electronics utilize current sense resistors for portable power management. As more devices become portable, higher currents and higher power ratings are critical, however, space for any portable electrical device must always be conserved.

Knowles Precision Devices are expanding its V-Series of single-layer capacitors by 100nF capacitor. In RF bypassing applications, the 100nF can help eliminate supply line noise. High-frequency monolithic microwave integrated circuit (MMIC) amplifiers with broadband gain need to be protected from RF noise on supply lines. Supply noise can mix with RF signals, impacting signal-to-noise ratios and potentially causing spurious output. A bypass capacitor provides an efficient path to the ground for RF energy on the supply line before it enters a gain stage.

Würth Elektronik Webinar.

Supercapacitors usually operate at low voltages of around 2.7 V. In order to reach higher operating voltages, it is necessary to build a cascade of serial connected SC cells. Due to production or ageing-related variations in capacitance and insulation resistance, the voltage drop over individual capacitors may exceed the rated...
