DK Corporation has developed the industry's first low-ESR soft-terminal laminated ceramic chip capacitors. This new CN series has terminal electrodes with a conductive resin layer, which can provide high mechanical strength and prevent substrate warpage. At the same time, the new laminated ceramic chip capacitors have a low ESR that is comparable to traditional products. CN series capacitors have 2.2 μF to 22 μF and rated voltages from 16 V to 100 V. Based on the X7R dielectric material, both the commercial grade grade and the automotive grade type of the new multilayer ceramic chip capacitors are available. The latter has passed AEC-Q200 certification, while the former will begin mass production and sales from April 2018.

Recently, Vishay Intertechnology, Inc. (NYSE: VSH) announced the launch of two AEC-Q101-certified transmissive light sensors, the TCUT1630X01 and TCUT1800X01, for automotive and industrial applications. The Vishay Semiconductors TCUT1630X01 and TCUT1800X01 are available in small 5.5mm x 5.85mm x 7mm packages and are the industry's first 3-channel and 4-channel transmissive sensors.
