Alps Alpine has announced the launch of what they believe to be the world’s smallest class surface-mount type TACT Switch, the “SKUB Series.” At just 2.4mm×1.4mm×0.55mm (W×D H), this switch achieves a smaller size than previous models, while maintaining the same tactile feel and durability. The SKUB series has an actuating force of 1.6N and a switching travel of 0.11mm. The initial contact resistance is 500mΩ. The IP68-protected component has a long service life of 500,000 switching cycles. It is designed for switching currents of 50mA at a maximum of 12VDC. Mass production began in September 2024.

Insight SiP launches next generation bluetooth radio in miniature integrated SiP package
Insight SiP is launching the ISP2454-MX module in a tiny package measuring 8 x 8 x 1mm, the smallest package on the market. With extended temperature capability up to 105oC, this device can support next generation Bluetooth based solutions including Angle of Arrival and the new Bluetooth Channel Sounding technology. Based on the new Nordic nRF54L15, this offers improved performance across the board, being based on a 4th generation radio and a double speed microprocessor compared with the nRF52 series-based devices, at a lower cost.
Nexperia enhances Zener diode portfolio to address overswing and noise phenomena
Nexperia has announced two enhancements to its extensive Zener diode portfolio that both eliminate undesirable overswing and noise behaviour – making a major advancement in Zener technology. Firstly, the new 50 µA-Zener series with B-selection (Vz +/-2%) and Vz ranging from 1.8 V to 51 V is offered in standard and automotive qualified variants. Making them ideal for automotive applications like on-board chargers in electric vehicles (EV) as well as for a broad range of industrial and consumer applications like general-purpose computing units, battery management systems, device chargers and smartwatches.
