A convenient desktop-accessible calculator of E-series component values
As explained in the E series Wikipedia page: “The E series is a system of preferred numbers (also called preferred values) derived for use in electronic components. It consists of the E3, E6, E12, E24, E48, E96, and E192 series, where…
Netgear’s LM1200: A 4G LTE modem, modestly funded
It may not support the latest-and-greatest cellular data tech. But in a pinch, it’ll cost-effectively still do the Internet-access trick.
In one of last month’s posts, covering cellular hotspots for maintaining broadband connectivity when…

Single-battery failures in multi-battery arrangements: diagnosing selective cell derangements
Why does one battery (or a few) in a multi-battery pack always seem to drain faster than others, and how does this outcome affect both its siblings and the system they jointly power? Read on.
A recent teardown noted a surprisingly (at least…
Why ISO/PAS 8800 is the new blueprint for AI safety in all critical industries
The rapid integration of artificial intelligence (AI) and machine learning (ML) into safety-critical systems is one of the most significant engineering challenges of our time. Whether it’s a medical device diagnosing an anomaly, an autonomous…
Isolated DC/DC modules raise power density
Leveraging IsoShield multichip packaging, TI’s isolated power modules deliver up to 3× the power density of discrete devices. The UCC34141-Q1 and UCC33420 reduce solution size by as much as 70% in isolated power designs for applications ranging…
High-res linear sensor tracks small displacements
The 40 LHE linear position sensor from Vishay measures strokes from 0 to 40 mm with ±1% full-stroke accuracy. Using Hall effect technology, it delivers 12-µm resolution and a lifespan exceeding 10 million cycles, making it well-suited for…
MOSFET ensures automotive thermal reliability
Diodes has added a 100-V MOSFET to its lineup of 40-V to 80-V devices, all in 8×8-mm gullwing-leaded packages for automotive systems. With a maximum on-resistance of 1.5 mΩ, the DMTH10H1M7SPGWQ is well suited for 48-V BLDC motor drives used…
TLVR power module supplies 320 A for AI processors
Infineon’s TDM24745T quad-phase power module with trans-inductor voltage regulator (TLVR) magnetics provides high current density for AI workloads. Integrating four power stages, proprietary magnetics, and decoupling capacitors in a compact…
Lightning-resistant TVS diodes safeguard avionics
Two TVS diode series from Littelfuse provide DO-160 Waveform 5A Level 5 lightning protection for avionics, military, and other mission-critical systems. The SM15KPA-HR/HRA and SM30KPA-HR/HRA offer peak pulse power ratings of 15 kW and 30…
LM555 begets basic bang bang thermostat
If your favorite tool is a hammer, every problem will look like a nail. Abraham Maslow
Given how often I tinker with the LM555 and LMC555 analog timers, Maslow might have written that famous aphorism specifically for me. And it. Well, here I…
