Inrush current, the spike that occurs when electrical devices are first switched on, is a recognised problem for many types of electrical equipment – and must be managed to guarantee the safety and long-term reliability of any installation.

Navitas Semiconductor has released its 4.5 kW AI data centre power supply reference design, with optimised GaNSafe and Gen-3 ‘Fast’ (G3F) SiC power components.

In electric vehicle (EV) charging and solar inverter systems, current sensors measure current flow by monitoring the voltage drop across a shunt resistor or the magnetic fields generated by current flowing through a conductor.

Applications for surface mount chip resistors with high power requirements typically result in increased circuit temperatures due to thermal resistance limitations. 

 Nexperia has unveiled the NPS3102A and NPS3102B electronic fuses (eFuses), the latest additions to its expanding range of power devices. 

EMIS has announced its new high-current three-phase EMC filter designed for PV and motor drive systems.

KEMET's APL90 series of aluminium polymer rectangular capacitors are now available through the Rutronik portfolio.

Traditionally, board-mounted AC/DC converters have been restricted to through-pin technology. However, RECOM has now simplified automated assembly by introducing components rated for JEDEC standard surface-mount reflow.

The TMCS1123 is a galvanically isolated Hall-effect current sensor with industry leading isolation and accuracy. An output voltage proportional to the input current is provided with excellent linearity and low drift at all sensitivity options. 

In this article, Electronic Specifier will answer the question - what is gallium nitride (GaN)? Also exploring where its origins lie, and how it’s being utilised today.
