Magnetoresistive sensors aim at industrial and white goods

Honeywell Standard Power Series mag sensors

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 ...

Panasonic offers small capacitor with big values

Panasonic - New FKS series

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, ...

PCB mounted chokes for 1- and 3-phase applications

02dec15schurter

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 ...

Failure should not be an option for Al capacitor

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 ...

Capacitor reliability can be improved with the right materials

Although not all applications are safety critical or mission critical, reliability is still a vital consideration for many electronic products. Making informed choices at the component selection stage can help ensure the product will perform correctly over its intended lifetime, writes James Lewis of Kemet. When choosing capacitors, properties such as volumetric efficiency, frequency stability, temperature rating or equivalent series ...

Kemet launches mission critical capacitors

The 0402DF series of chip inductors offers higher inductance and significantly lower resistance compared with previous 0402-sized inductors, claims maker Coilcraft. There are 25 values from 20nH to 3.3µH (+/- 5%). As an example of resistance, the 220nH value is 240mΩ – 55% lower than the same value in Coilcraft’s 0402AF sSeries “making it optimised for use as a harmonic ...

Tunable capacitors for 4G smartphone PAs

STPTIC-Tunable-Capacitors_IMAGE-2-300x198.jpg

STMicroelectronics has extend the tuning range of its electronically tunable capacitors. Designated the Stptic G2 range, the capacitors now have a 5:1 tuning ratio which means they can add extra correction when signal matching  between a smartphone’s antenna and power amplifier. Other improvements include lower parasitic resistance and inductance as well as a higher ESD rating. Designed to meet linearity specifications of 3G/4G modulation, ...

AVX launches SpiTAN IV

AVX tantalum capacitor

AVX has introduced a simulation tool, SpiTAN IV, for its tantalum, polymer, and niobium oxide capacitors. Using data mined from the libraries of AVX’s previous PSpice Models and S-Parameters S2P software, which are now redundant, the SpiTAN IV software allows design engineers to review electrical and performance characteristics for individual part numbers by temperature and frequency, allowing them to identify ...
