Q Tech Corporation has announced the QT25HF Lamb Wave Oscillator and QT25VHF Voltage Controlled Lamb Wave Oscillator for RF applications from 400MHz to 1.3GHz, with phase noise down to -168 dBc/Hz and calculated integrated RMS jitter of 8.08 femtoseconds at 500 MHz. Designed for aerospace, defense and industrial systems, the devices provide frequency stability of up to ±50ppm over -55°C to +125°C and as tight as ±20ppm over −20°C to +70°C, giving engineers a compact drop-in option with tighter temperature stability than typical SAW-based solutions.

has introduced the MH1608A series high current chip ferrite beads, an AEC‑Q200-compliant automotive-grade family for high-frequency noise suppression in space-constrained automotive power supplies and high-density PCB assemblies. The series combines a 1.6 × 0.8 × 0.8 mm package with impedance from 30 Ω to 1000 Ω at 100 MHz, maximum DC resistance from 0.02 Ω to 0.20 Ω, rated current up to 5 A and an operating range of −55 °C to +150 °C to support EMI control with low power loss and reduced temperature rise. RoHS-compliant and halogen-free, the ferrite beads also help designers meet automotive qualification requirements while preserving routing space and thermal margin in dense layouts.

STMicroelectronics has introduced the L6462A, a transition-mode power-factor correction controller for consumer products and power supplies up to 250W that supports 90-264V AC input and typically delivers 400V output. By eliminating external voltage-divider components, auxiliary inductor winding and related interface parts, the device helps reduce BOM cost while improving efficiency, with features including quasi-resonant valley […]

B&K Precision has introduced the DML Series DC electronic load system, a modular platform with a 4U mainframe that supports up to four channels and 800 W. The system uses swappable single- or dual-channel load modules with front-panel inputs providing up to 80 V and 80 A, or up to 160 A in parallel operation, […]

Bourns has introduced the CDSOD323-TxxSC-Q Series, an automotive-grade bidirectional TVS diode family for single-line protection against ESD and surge events in space-constrained designs. Offered in a compact SOD-323 surface-mount package, the series provides up to ±30 kV ESD protection, 400 W peak pulse power on an 8/20 µs waveform and AEC-Q101 compliance, helping designers meet […]

Insights from the Edge AI Conference on bridging the gap between pilot projects and real-world applications.

I’ve recently had a run of bad luck with the various technology-based products on which we depend so heavily. Whether this is just a coincidence or the technology gods decided it was my turn, I can’t say (there doesn’t seem to be a connection, but you never can be sure with these things).

Microchip Technology has announced the DSA504RT, a radiation-tolerant six-output programmable clock generator for aerospace and defense systems that require stable timing when GNSS signals are weak or unavailable. The device integrates an analog PLL with spread spectrum capability, two fractional dividers, two integer dividers and six configurable output buffers, delivering jitter as low as 200 fs from 12 kHz to 20 MHz and supporting output formats including LVPECL, LVDS, HCSL and CMOS. Offered in QFN28 and CQFP32 packages, the DSA504RT can replace multiple oscillators, crystals and buffers to reduce component count, power, mass and timing distribution complexity.

Melexis has introduced the MLX91229, a conventional-Hall current sensor with a sigma-delta digital output for current sensing from 200 A to 2000 A in electrically noisy automotive environments. Designed for traction inverters and other high-power vehicle systems, the IC shifts signal transmission from analog to digital to help maintain signal integrity where EMI, longer PCB traces and wiring can affect measurement accuracy. The device also uses the same footprint as existing analog Hall-effect solutions, allowing evaluation of digital current sensing without major layout changes.

Implementing robust sensor security is essential in connected systems. Compromised sensors can feed corrupt, inaccurate data directly into operational systems, leading to devastating real-world failures, catastrophic physical damage, safety concerns, and compromised decision-making.
