Vishay has introduced a 5A 30V solid-state relay in a SOP-4 surface-mount  package. VOR1003M4T is an industrial-grade relay with a 1 Form A (single-pole normally-open) contact. On the output side there are back-to-back mosfets allowing ac or dc to be switched. Typical output-side figures are: 0.7Ω Rds(on), 500μs Ton, 100μsToff and <1μA leakage. These switching times are with 10mA drive ...

Same Sky has released a family of 62 plastic knobs, designed for 6mm diameter D-cut shafts. All numbered SPK…, these offer: a variety of colours, diameters from 10 to 32.5 mm, heights from 8.5 to 19.45mm, ribbed or smooth surfaces, and compatibility with shaft lengths from 4.2 to 15.6mm. Use is foreseen with rotary potentiometers and encoders. Find the Same ...

Allegro MicroSystems today announced three ICs: two analogue current sensors and a motor driver for fans. The first current sensor, ACS37630, is designed to be sat on top of a bus bar and partly surrounded by a U-core magnetic field concentrator. “Its vertical Hall technology enables sensing parallel to the package surface, ideal for system integration with U-core magnets,” according ...

FCL Components has introduced signal switching relays for electric vehicle power monitoring. “Conventional signal relays have often been used to switch signals for on-board equipment in electric vehicles,” according to the company. “However, electric vehicle batteries usually use 300 to 400Vdc. This exceeds the expected usage range of many signal relays.” There are three types, each available in multiple variants: ...

Emil Otto has developed flux gels for manual rework on solar modules, that are based on solar module production fluxes. Fluxes for manual and rework soldering tend to contain “different activators to those used for series production”, according to the company. “Thanks to the uniform activators of the Emil Otto flux gels, cross-reactions that can occur when using different activators ...

Same Sky has added to its portfolio of disc-shaped piezoelectric elements, with devices from 12 to 35mm in diameter and down to 0.12mm thick. Picking the 12mm x 0.12mm CEB-12012-L100 as an example, it has pre-attached 100mm flying leads, which not all of the new parts have, and can be driven with up to 30Vp-p. Resonant frequency is specified without ...

Standex Electronics has created a reed relay that measures 7.95 x 4.67 x 3.6mm and can switch 100V, 200mA, 3W or 8GHz. 8GHz is the -3dB frequency, at which the switch offers -5dB isolation when open. There are two versions: UJ-103RF has a 3.3V 90Ω coil UJ-105RF has a 5V 150Ω coil “This series is designed to meet the demand ...

Maxon has published a handbook about DC drive system selection. “The book includes a six-step flowchart, providing a clear path to select the drive system specific to application requirement,” said the company. “The chapters dedicated to each drive system component also offer the formulae required to select the right product at each stage. Illustrations and descriptions of the variables bring ...

xMEMS has created a micromachined silicon earbud loudspeaker that does not need a booster amplifier. Instead, Lassen, as it will be know, will run from a standard 1Vrms audio signal, delivering up to 115dB SPL across 6kHz to 20kHz – making it a tweeter. It measures 3.2 x 5 x 1.15mm, and is aimed at two-way ‘true wireless stereo’ (TWS) ...

Wevo has introduced a series of runnier silicone potting gels to fill spaces more quickly. “Whereas most standard products have viscosities in the region of 1,000mPa·s, the two-component silicone gels in the Wevosil series offer around 500mPa·s,” according to the company. “That not only enables faster filling of complex component geometries, it also improves air bubble elimination with electrical encapsulation ...
