The new thermistors directly benefit from Murata’s proprietary ceramic technology, with innovations realized about the raw material composition and sintering procedure. The result is that a significant downsizing can be achieved without any compromise in performance. Furthermore, the thermistors have strong operational stability and do not generate any noise which would otherwise affect neighboring components.

Cornell Dubilier has announced that additional capacitance values and cell sizes have been added to its already extensive supercapacitor platforms, the DGH 2.7 volt and DSF 3.0-volt series. The expansion comes on the heels of the recent addition of cutting-edge LiC hybrid types which offer higher operating voltages and greater energy densities. Supercapacitors (aka EDLCs or ultracapacitors) are rapidly becoming essential components for power circuit designers. They are used to supplement rechargeable batteries or as replacements for batteries in a very diverse range of applications.

Kemet Webinar

Despite all the advances in electronics, the challenge of electromagnetic interference (EMI filtering) persists. As switching frequencies increase, the electronic emissions also increase in frequency. Those higher harmonics may sometimes be lower in magnitude, but they can still cause problems for the increasingly sensitive devices.
