Technical articles, selection guides and industry insights about electronic components, sourcing and PCB design.
Analog ICs and power discretes are back on allocation. By Q2 2026, lead times for STM32-family MCUs and TI MSP430 variants have stretched past 26 wee…
Most datasheets run 30 to 80 pages. No engineer reads them cover to cover, and you should not either. What matters is knowing which sections carry th…
Choosing the wrong connector costs more than a re-spin. It costs field downtime, safety recertification, and lost production. This guide breaks indus…
A 01005 capacitor occupies 0.4 mm × 0.2 mm of board real estate, roughly the cross-section of a human hair. Fifteen years ago that package was exotic…
Buying ICs from Shenzhen, PCBs from Malaysia, or passives from a UK distributor post-Brexit means customs will eventually ask for paperwork you did n…
Most engineers send a part number list and wait. Procurement teams that get it right send a structured RFQ and close the gap between BOM cost estimat…
You find the exact capacitor your design needs. Voltage rating and tolerance are perfect, the price is reasonable. Then the MOQ is 4,000 pieces when …
A part goes EOL six months before your production run. The sole-source op-amp is on 52-week lead time. Or procurement flags a $14 IC and asks if the …
Selecting the wrong AC/DC power supply can cook your PCB, inject noise into sensitive analog front-ends, or force a late-stage respin when you realiz…
Most power electronics engineers reach for N-channel MOSFETs by default. The reason is physics: electrons move through silicon about 2.5x faster than…
A BOM line saying "10kΩ, 0603, 1%" hides dozens of variants across manufacturers, with TCR figures from ±25 to ±200 ppm/°C and 10× price spreads. Thi…
Pick the wrong capacitor and your voltage rail oscillates. Pick the right one and the board runs quiet for a decade. The choice between ceramic (MLCC…
