Matsuo MQT series thermostats are IP64 rated, have excellent repeatability (within ±0.2K) and life-cycles of upto 1 million operations. They out-perform cheaper disc thermostats on every level and help to minimise costly maintenance calls.

Vishay has announced two new series of Bulk Metal Foil ultra-high-precision Accutrim trimming potentiometers. The 3/4-in rectilinear devices offer extremely low end-to-end TCR of ± 5 ppm/°C (1285G) and ± 15 ppm/°C (1280G) from – 55 °C to + 125 °C, + 25 °C ref., and ± 25 ppm/°C through the wiper, load life stability of 0.1 % typical under full rated power at + 25 °C for 2,000 hours, and a < 0.05 % typical settability.

Vishay has announced that it is expanding its WSR series of Power Metal Strip resistors with the industry's first such device to offer a 5-W power rating in the 4527 package size.

A range of new options for Series 71 PCB-mount switches has been introduced by EAO. Coloured lenses with a choice of illuminated symbols including the popular on/off design plus ‘ring’ and ‘centre spot’ illumination are now offered as standard. These lenses are an excellent way to enhance the aesthetic design of a control panel and improve the industrial ergonomics of the operating environment, whether it's for a luxury yacht, a medical i...

ON Semiconductor has introduced two ESD protection devices housed in its new, ultra-small 0201 Dual Silicon No-Lead (DSN-2) package. The DSN style package, which measures a mere 0.6 mm x 0.3 mm x 0.3 mm, enables 100 percent utilization of the package area for active silicon, offering a significant performance-per-board-area advantage compared with products in plastic molded packages.

Vishay has announced the release of three new ultra-high-precision Bulk Metal Z-Foil surface-mount resistor networks that offer the best combination of stability features ever achieved in the ball grid array (BGA) format. The devices provide absolute TCR of ± 0.05 ppm/°C from 0 °C to + 60 °C and ± 0.2 ppm/°C from − 55 °C to + 125 °C, + 25 °C Ref., PCR tracking (“ΔR due to self heating”) of ± 5 ppm at rated power, and a lo...

ZF Electronics, (formerly Cherry Electrical Products), has detailed how its switches and sensors are used in on-demand or tankless water heaters which have increased in market share significantly in recent years. Newer technologies offer the domestic consumer significant advantages over conventional systems, as they provide instantaneous hot water and are more cost-effective than stored water systems because they only heat water as it is needed,...

Maxim has introduced the MAX14529E/MAX14530E overvoltage protectors (OVPs) with USB charger detection. These devices employ an integrated MOSFET to protect low-voltage systems against voltage faults up to 28V, thus eliminating the need for an external nFET.

C&K Components has developed a broad line of detect switches for ATCA (Advanced Telecom Computing Architecture) and AMC (Advanced Mezzanine Card) use in portable medical equipment. The HDS, HDT, MDS, SDP, SDS and SDT Series detect switches are implemented on the server blade of the ATCA equipment or on AMCs as a safety mechanism to verify that the blade is powered down (processing), ensuring no data is lost.

Vishay has announced a new QPL series of Bulk Metal Foil ultra-high-precision Accutrim trimming potentiometers designed to meet and substantially exceed the requirements of MIL-PRF-22097 Char. F. For avionics, military, and space applications (AMS), the QPL approved 1/4-in square RJ26-style devices offer low end-to-end TCR of ± 10 ppm/°C from − 55 °C to + 150 °C, + 25 °C ref., and ± 25 ppm/°C through the wiper, load life stability of...
