Murata claims smallest inductors

Murata LQP01HQ

Murata is claiming a miniaturisation record with ‘high-frequency’ inductors that have a 0.25 x 0.125mm footprint, and are 0.2mm tall. Officially 008004 size, and called the LQP01HQ series, they apparently have the same Q characteristics as its previous 0.4×0.2mm (01005/0402) LQP02TN range, which have Q=15, but with half the board mounting area. That said, its existing 01005 devices also include LQP02TN  (0.2mm ...

Würth transformers operate up to 10Gb/s

image

Wuerth is adding to its Ethernet modules with LAN transformers for speeds of up to 10 Gbit/s. The transformers support Power over Ethernet (PoE) up to 100 W and currents up to 1 A per channel. Würth Elektronik eiSos says it is the only manufacturer to offer 10-Gbit LAN transformers with an extended temperature range (-40 to +85 °C). WE-LAN ...

100µm thick silicon capacitors designed for smart cards

Untitled

IPDiA, the French firm developing 3D silicon passive components, has announced a range of low profile capacitors for smart cards and RFID tags. The capacitors are just 100µm thick, and despite their small size they have ESD performance up to 8kV. The devices are likely to be used in contactless smart cards for antenna matching, RF filtering and decoupling of ...

Vishay welds 24kW resistor for reliability

Vishay has gone for welded constriction, ceramic insulators and stainless steel plate elements for robustness in its GRE2 ‘Milwaukee’ resistors, which can dissipate up to 24kW. The double-insulated devices can operate at up to 400°C and are aimed at capacitor pre-charge, capacitor discharge, dynamic braking, load testing, heating, and neutral grounding applications in locomotives, transit systems, harmonic filters, renewable energy systems, and industrial systems. ...

Socionext, the Fujitsu-Panasonic SoC jv, is in volume production of a camera front engine specialized for Bayer data processing that supports the latest sensors. The MB86S29 is a Milbeaut Image Processor aimed at smartphones. By supporting the latest image sensors, the MB86S29 lets module makers implement these functions without replacing their application processors. Recently, it is common to find cameras ...

Melexis introduces elevated current version of its Hall-effect sensors

image29-300x209.jpg

Melexis has an elevated current version of its MLX91208 series of programmable Hall-effect current sensors. Optimised for the very high fields of hybrid and electric vehicle (HEV) applications, the MLX91208CAV can cope with up to 1000A of primary current. This device complements the existing MLX91208 products which cover low field and high field functions. Thanks to the proprietary integrated magnetic ...

Water repellent coating improves capacitor reliability

Murate-water-shedding-capacitor-before-300x81.jpg

Murata has developed a water-repellent coating that it claims will increase the reliability of multi-layer ceramic capacitors. At issue is condensation – not just between the PCB and he capacitor, but on any capacitor surface that can gather condensation. When water wets the surface of the capacitor – top diagram – electromigration of electrode metals can occur which can eventually ...

Kemet has X7R high-temp capacitors

Kemet has announced its industrial grade high temperature X7R dielectric capacitors which it says can utilise the full rated voltage at 175°Celsius. The devices are offered with a flexible termination option and are RoHS compliant without exemption. These high temperature capacitors are for a variety of applications in extreme environments such as down-hole oil exploration, aerospace engine compartments, geophysical probes, ...

Melexis evaluation kit supports ToF sensors

Melexis-EVK75023-300x197.jpg

Melexis is supporting its time-of-flight (ToF) sensing technology with the EVK75023 evaluation kit which accompanies its MLX75023 QVGA (320x240pixels) resolution ToF sensors. This new hardware platform enables implementation of more advanced human machine interfaces (HMIs). Co-developed with BlueTechnix, the EVK75023 is a 130x105x60mm board for assessment of ToF sensing capabilities under challenging conditions, where the detrimental influence of ambient light ...
