Switch is approved for use in explosive atmospheres

Switch is approved for use in explosive atmospheres
SCHURTER develops and manufactures state of the art switch and pushbutton technologies including microswitches, piezo elements, switches with mechanical actuation, metal pushbuttons and keypads as well as display elements. A key focus is Metal Line. With the certification in accordance to ATEX and IECEx, the first switch from the PSE family is now approved for use in potentially explosive atmospheres containing air and gases. This is available with a diametr of 19 and 22mm.

Storage choke has low DC resistance

Storage choke has low DC resistance
Würth Elektronik iBE is bringing an SMT-capable storage choke into the market which is pick-and-place and reflow-capable. The WE-FLAT-I flat wire power inductor is a storage choke with low DC resistance, high current rating, high saturation current magnetisation and an operating temperature that ranges from -40 to +150°C. A narrow air gap in the leg reduces the stray field. With its low, compact construction, the component offers excellent planarity and three-point attachment to the board.

Anti-sulfur chip resistor arrays utilise thick film technology

Anti-sulfur chip resistor arrays utilise thick film technology
  Stackpole Electronics announces the release of the RAVS series of convex termination anti-sulfur chip resistor arrays. The RAVS series utilises thick film technology with lower silver inner terminations to significantly reduce the susceptibility of the array to contamination by sulfur.

Mitigating spark flash dangers in hazardous environments

Mitigating spark flash dangers in hazardous environments
Wherever sources of sparks or excess heat are present, substances such as gases, petroleum products and airborne dusts or fibres pose a serious risk of triggering an explosion and subsequent fire. To minimise these losses, regulatory bodies around the world have worked to refine standards that will mitigate the spark flash potential that can be found in these working environments. By Bharat Shenoy, Littelfuse.

Protecting electronic circuits & interfaces from ESD

Protecting electronic circuits & interfaces from ESD
Designers of today’s electronic devices have demanded more functionality with greater flexibility and higher levels of user interaction. These circumstances have helped in driving the development of nanometre chipsets along with a multitude of user interfaces or ports. The confluence of these two has made electronic devices more susceptible to ESD and required the need for a more robust solution.

PHS capacitors handle high voltage management applications

PHS capacitors handle high voltage management applications
The T550 and T551 series Polymer Hermetic Seal (PHS) capacitors from Kemet are now available in Europe from distributor TTI. The components have specifically been designed for high voltage management applications and feature conductive organic polymer as the cathode plate of the capacitor instead of the traditionally used MnO2 or wet electrolyte.

Precision thick film chips now offer 0.1% tolerances

Precision thick film chips now offer 0.1% tolerances
Stackpole Electronics announces its tolerance expansion for the RGC series. The thick film technology is now available in ±0.1% tolerances in chip sizes from 0603 through 2512. This development is a significant enhancement to the series that allows engineers to take advantage of precision tolerances while avoiding design challenges associated with thin film resistors, namely high moisture/humidity.

COTS+ tantalum capacitors suit critical military systems

COTS+ tantalum capacitors suit critical military systems
AVX has released a COTS+ version of its TCR Professional Series polymer tantalum chip capacitors. Designed for use in critical military systems, the TCB series features conductive polymer electrodes, which enable extremely low ESR and reduce the potential for ignition failure. Each batch undergoes lot conformance testing and additional reliability level verification in order to provide higher reliability than standard polymer tantalum capacitors.
