200°C wet tantalum capacitors are tough for the hard life

Vishay is aiming at oil exploration, aerospace and the military with high-temperature wet tantalum capacitors. The surface-mount T24 series consists of two devices, both 9 x 7.1 x 7.4mm (case code ‘C’). 33μF – 45V at 200°C  (75V -55 to 85°C)  2.5Ωmax ESR (+25°C 120Hz) 10μF – 75V at 200°C  (125V -55 to 85°C) 5.5Ωmax ESR ...

Dispensing Filled Materials

Fillers are one of the most important ingredients in an adhesive, sealant or encapsulant. Some materials contain a single filler, while others have multiple fillers. These fillers may account for up to 50 percent of the product's ingredients.

Audio-free industrial PCs side-step chip shortage

Responding to an international shortage of audio chips, Advantech has developed non-audio version of its most popular motherboards to help mitigate supply issues. “GPUs were perhaps always destined for shortage, but one area now being seen are the unprecedented shortages in the world of audio,” according to UK-based Impulse Embedded, which stocks Advantech-based industrial PCs. “As ...

125°C photovoltaic coupler outputs 14V for high-voltage mosfets

Toshiba has upped the output of a photovoltaic generator to drive high-voltage power mosfets in galvanically-isolated solid-state relays (SSRs). The device is the TLP3910, with a minimum open voltage of 14V – double that of the earlier TLP3906. TLP3910 is also Toshiba’s first photovoltaic coupler with a minimum isolation voltage 5kVrms. “Along with the creepage ...

Intermetallics and airgaps for 1nm nodes and beyond

Imec has presented an experimental study of Al-based binary compounds, with focus on their resistivity behavior. For example, for stoichiometric AlCu and Al2Cu films, a resistivity as low as 9.5µΩcm was reported. These results experimentally support their promise to be used as new conductors in advanced semi-damascene interconnect integration schemes, where they can be combined ...

MIT designs circuits based on protein-protein interactions

Synthetic biology offers a way to engineer cells to perform novel functions, such as glowing with fluorescent light when they detect a certain chemical. Usually, this is done by altering cells so they express genes that can be triggered by a certain input. However, there is often a long lag time between an event such ...
