By Barry Brents, Littelfuse, Inc. Load-powered latching relay architecture enables battery-free HVAC control designs while reducing system complexity, size, and power consumption. Designing around power constraints, not features Despite advances in connectivity and embedded processing, one limitation continues to constrain smart thermostat design: power delivery. Many HVAC systems in the field still rely on two-wire […]

Compact SMD UVC LEDs support UVGI designs
Marktech Optoelectronics has released 280 nm UVC LEDs, a series of single-, two-, and four-chip emitters in 3.5 × 3.5 mm to 7.0 × 7.0 mm SMD packages, with optical power ratings from 28 mW to 360 mW and forward current ratings from 100 mA to 700 mA depending on the device. The 280 nm […]
Embedded passives enhance vertical power delivery
Saras Micro Devices has developed technology to embed capacitors and inductors into semiconductor substrates and PCB laminates. Doing so keeps them close to loads through vertical power delivery, Every day, we hear about the need for more power to satisfy AI chips. The combination of low voltage and high current (1000s of amps) means that […]
402 nm laser diode delivers 4.5 W in TO-9
Nuvoton Technology has started mass production of its KLC434FL01WW violet laser diode, delivering 402 nm wavelength output at 4.5 W in a 9.0 mm TO-9 CAN package for optical systems. The device uses an optimized structure and thermal design to improve wall-plug efficiency and heat dissipation, enabling stable continuous-wave operation and extended lifetime under high-power […]
Modular DAQ system supports GPS and PTP synchronization
B&K Precision has introduced the DAS1820 portable high-speed data acquisition system, a compact dual-slot recorder that uses the same D18 plug-and-play module ecosystem as the DAS1800. The system supports simultaneous sampling up to 1 MSa/s per channel for up to 8 channels with compatible modules, measures up to ±1500 VDC or 1000 Vrms with CAT […]
How are accelerated life tests changing for high-voltage EV power electronics?
For many years, standards such as AEC-Q101 and the “test-to-pass” method were the only ways to enter automotive power electronics. But since the powertrain has become electric, these static qualification methods are no longer enough. Electric Vehicles (EVs) use high-voltage traction inverters that must handle changing thermal and electrical stresses not covered by standard industry […]
