MEMS oscillators from SiTime have been added to the range of IoT-targeted frequency control products available from AEL Crystals. The company explains that the IoT brings fresh challenges for frequency control manufacture as it requires products to accommodate multiple protocols, such as Bluetooth,  ZigBee, Z-Wave, 6LoWPAN, CSR Mesh / Bluetooth Low Energy, Sigfox and Thread. Designs are also expected to require lower power consumption ...

ON Semiconductor introduces CMOS image sensors with Near Infra-Red+ (NIR+) technology

TDK claims to have created the smallest common-mode choke for automotive Ethernet applications. Its dimensions are 3.2 mm x 2.5 mm x 2.5 mm. The ACT1210L choke, which is qualified to AEC-Q200, retains the Scd21 mode conversion characteristic of the previous generation product, the ACT45L. According to the supplier, this key parameter expresses the amplitude relationship between differential and common-mode ...

Recent advances in polymer-cathode technology and improvements in tightening the tantalum supply-chain are allowing more designers to choose polymer tantalum capacitors as alternatives to traditional solid tantalum capacitors, writes Roger Tall In specifying the ideal capacitor most designers would start with high volumetric efficiency and then consider miniaturised packages and capacitance stability over applied voltage, frequency, temperature and time. A ...

The small low-loss metallised polypropylene film capacitors for active filters, high frequency circuits and high current circuits.

Panasonic Automotive & Industrial Systems says its latest aluminium electrolytic capacitors are designed for higher ripple current handling. The V-TC and V-TCU series capacitors have from 1.2 to 1.5 times higher ripple current capabilities at 125°C, says the supplier. The specifications are for the V-TC series 300mA for D8 can size up to 750mA for G can size and V-TCU ...

Honeywell has added to its line of magnetoresistive sensors. Cryptically called the Standard Power Series, there are four devices in all, aimed at industrial, medical and white goods applications. The firm is thinking: flow sensing in air conditioning, anti-tamper detection in utility meters, RPM sensing in exercise equipment and door position detection, to name but a few. The most sensitive ...

A range of aluminium electrolytic capacitors from Panasonic Automotive & Industrial System are available in can sizes measuring down to 4×5.8mm. This is a significant reduction in can size on previous capacitors, said the supplier. The FKS series offers increased capacitance values than previous products. For example, the new 25V 33µF FKS capacitor, which comes in a 4×5.8mm can size, ...

Schurter’s has increased the current rating of its current compensated chokes which can now be PCB-mounted. Designated the DKIH series, the chokes are available for single and three phase applications with rated currents from 10A to 50A. To meet EMC requirements there are advantages to design a filter on PCB with discrete components, according to the supplier. “Capacitors and a ...

The aluminium capacitor is a common feature of power supplies, since it is the most suitable for functions such as energy storage and low- or high-frequency filtering. Unfortunately, aluminium capacitors are also often the components most prone to failure: the operating lifetime of an aluminium capacitor will tend to determine the operating lifetime of the entire power supply, writes Marcin Chelminski ...
