Toshiba has announced three photorelays that are aimed at applications where they will replace mechanical 1-form-A relays in industrial and factory automation installations. Based upon the U-MOS IX semiconductor process with a trench structure, the TLP3106A, TLP3107A and TLP3109A have RON(max) values of 30mΩ, 40mΩ and 65mΩ respectively. They offer options including an off-state output terminal voltage between 30-100V and ...

Kemet has launched the R41T and R76H series AEC-Q200 qualified metallized polypropylene film capacitors. The series is aimed at automotive applications, including those for electric vehicle (EV) powertrains and Advanced Driver Assistance Systems (ADAS). The capacitors have a 125ºC maximum operating temperature and exceed the requirements of 85ºC/85% relative humidity temperature-bias-humidity tests. They support the design of “high-performance, high-reliability” circuits ...

Spanish wound component maker Premo has significantly reduced choke operating temperature through thermally-conductive potting, branding the added material ‘CoolMag’. “CoolMag is a thermally conductive compound able to fill any space between winding and core, and between core and heat-sink,” said the firm. “It is enough to reduce temperature by more than 40ºC.” (graph right) To find a suitable potting compound, ...

Omron is moving into the high power relay market with a 100A device featuring ≥5mΩ contact resistance. The G7EB is aimed at distribution power conditioning systems (PCS) as well as test equipment such as semiconductor testers. The device can switch up to 100A at 800Vac. Its 5 milli-ohm contact resistance is claimed to greatly reduce heat generation within the component. ...

Skeleton has had its SkelCap SCA0300 super-caps UL-certified

TDK-Lambda has announced quarter brick EMC filters with a rating of ±40Vdc at 20A and a choice of flanged or non-flanged baseplates. Called the FQA series, they are intended for harsh and demanding environments including MIL-COTS vehicle and airborne. Differential and common mode noise attenuation is described as sufficient to simplify system level compliance to MIL-STD-461G by the firm, and input spike protection is ...

Taiyo Yuden is manufacturing AEC-Q200 (automotive passive component standard) qualified surface-mount noise suppression inductors for power leads. “Based on our unique internal structure and material technology and structural design, FB Series Type T has achieved an operating temperature of 150°C and is suitable for wideband noise suppression up to GHz frequencies,” according to the firm. The device is 1.6 x ...

Electrocube 958A high current metallised polypropylene film dc link capacitors are intended to provide durability in extreme operating conditions. “The series is rated at 100,000 hours at 70°C,” according to New Jersey based component distributor New Yorker Electronics, which is stocking the parts. “In applications such as electric vehicle power conversion, aircraft power systems, battery chargers and other high pulse applications, ...

Cornell Dubilier has released ‘ultra-flat’ aluminium electrolytic capacitors, intended to replace arrays of surface-mount capacitors. PCB terminations are flat ribbon-lead surface-mount types, whose flexibility allows the body to be mounted remote from the PCB. The bodies are 62 x 42mm, and either 2.2mm (max, ‘DA’ case) or 3.2mm (max, ‘DB’ case). Weight is 17g (DA) or 22g (DB). “Due to its light weight, ...

The Raspberry Pi Foundation and Panasonic Industry Europe have donated 100 Raspberry Pis to the Lycee D’Akwa-Nord Bonamoussadi High School and the University of Science in Douala. In total over 250 pupils – undergraduate, graduate and doctoral students – together with their professors followed the educational and demonstration sessions after the computers were handed over, according to Panasonic, which will ...
