Lorlin Electronics, one of Europe’s longest established switch manufacturers, will be previewing their new range of vandal proof keypads at Electronica 2008. The new KP range offers 1, 2, 3, 4, 12 and 16 button versions for applications requiring a simple push button control to complex alpha numeric security entry systems. The keypads are available in black or grey finishes to meet system design requirements and may be LED illuminated with a wi...

Murata has developed two new series of low-profile wirewound chip inductors for use in DC-DC converter applications. Both the LQH3NP_M0 series and LQH3NP_G0 series of inductors offer low DC resistance, vital for DC-DC converter applications as it prevents energy dissipation from the inductor, improving the converter’s overall efficiency.

Cherry Electrical Products has released an application note giving details of its miniature switches and sensors for operating automated valves in inaccessible or remote locations or when the use of manual handwheels presents practical difficulties. Valves are often operated by a manual handwheel, but there are many circumstances when this is impossible – for example, when the size or differential of a valve means the handwheel pull is beyon...

Tyco Electronics has announced the introduction of a new line of PolySwitch circuit protection devices. Designed for use in a wide variety of general electronic products -- ranging from industrial controls to battery packs -- the new PolySwitch RKEF devices are functionally equivalent to the company's existing RXEF overcurrent protection devices, but are available in a significantly smaller form factor.

Developed initially for passenger aircraft seating controls, a new capacitive switching system from WASP is easily adapted for use in almost every situation where non-mechanical switching is required. A conventional printed graphic overlay, protected by clear acrylic or polycarbonate is used together with a circuit design which operates a switch using the user’s natural body capacitance. The switch panel uses a proprietary capacitive sensor...

Vishay Intertechnology has announced the release of three new X2 electromagnetic interference (EMI) suppression film capacitors with an increased maximum mains voltage of 310 VAC and a wide range of lead pitches and capacitance values.

Murata Power Solutions has enhanced its radial lead and toroidal surface-mount inductor portfolios with the addition of four new ranges of RoHS compliant components. The introductions comprise over 50 new part numbers that reinforce Murata Power Solutions’ reputation as a provider of industry-leading magnetic products.

ON Semiconductor has announced two new members of its low capacitance Electrostatic Discharge (ESD) protection product line - the NUP4016 and the ESD11L5.0D. These new products utilize ON Semiconductor’s patented, leading-edge, integrated ESD protection platform, which enhances clamping performance while maintaining ultra-low capacitance and small die size. Offered in ultra-small packages that provide a 20 percent lower profile than previou...

KOA has developed flat chip resistors with extremely high resistivity against sulphurated environments, high humidity and high temperature. The enhanced structure is based on a metal glaze thick film. Tests in H2S environment showed an outstanding performance compared to standard products.

knitter-switch has published a new 24 page product shortform catalogue detailing the company’s extensive product ranges designed for the consumer, IT, industrial, medical, telecomms, broadcast and instrumentation markets.
