STTS22H Sensor by STMicroelectronics
STTS22H Sensor by STMicroelectronics

STMicroelectronics’ STTS22H has a typical temperature-reading accuracy of 0.25°C and low operating and standby current, enhancing temperature and heat-flow monitoring in asset trackers, shipping-container loggers, HVAC systems, air humidifiers, refrigerators, building-automation systems, and smart consumer devices. It is I²C and SMBus 3.0 compliant, and supports flexible operating modes, including configurable output data rate (ODR) down to 1Hz, a power-saving one-shot mode, and an interrupt pin that supports SMBus Alert Response Address (ARA). Power consumption is very low, drawing just 2.0µA at 1Hz ODR and 1.75µA during periodic one-shot measurements. In standby mode with the serial port inactive, it draws 0.5µA (typical), while the 1.5 to 3.6V operating voltage range allows use with various power sources, like a small lithium cell.

SMK’s PB-F2 Series Connector
SMK’s PB-F2 Series Connector

SMK Corporation has developed the PB-F2 Series 0.5mm-pitch board-to-board connector with a floating structure for automotive devices to meet demands for miniaturization and high-speed transmission. It has one of the industry’s smallest-class mounting areas of 201mm2 for the 120-pin model. Its floating structure absorbs ±0.5mm gap in the X and Y directions and +0.5mm in the Z direction. Having matched differential impedance of 100Ω, it supports high-speed transmission of up to 6Gbps. It features 5.7mm mounting height receptacle, 7.25mm for the plug, and 10mm stack height. Designed for automotive devices such as infotainment systems, display audio, car navigation equipment, engine control units, it is available both with and without electromagnetic interference (EMI) shielding structure, and operates from -40 to 105°C.

TDK’s MAF Series Noise Suppression Filters

TDK’s MAF Series Noise Suppression Filters

TDK Corporation has expanded the MAF Series of noise suppression filters with MAF1608GAD121L- and MAF1608GAD201L designed for audio lines. These compact (1.6×0.8mm) multilayer filters are able to suppress noise at cellular frequencies from 1GHz and Class D amplifier noises and ensure high attenuation quality. They offer rated currents of 3.2A and 2.3A, respectively, and low DC resistances of typically just 0.021Ω and 0.045Ω. Their impedance at 900MHz is 120Ω and 200Ω, respectively. Their low DC resistance and high rated current of more than 2A make them suitable for smart speakers and external speakers for tablets that require power levels of 2W or higher as well as for headphones and microphones.
