A bench instrument restoration had to begin by replacing its mains-rated film capacitors before the unit could be safely powered at all. That ordering says something about how passive components age.
Thin film resistors are moving onto aluminum nitride substrates. The interesting part is not the material itself but what it says about where precision circuits are now expected to survive.
Anti-surge chip resistors are reaching 0.33 W in an 0402 footprint. The number is incremental; what it says about board area, transient exposure and second-source strategy is not.
A traction-inverter PMIC combines multi-rail power, resolver excitation and independent safety supervision, changing how engineers approach passives, layout, reliability and sourcing.
AlN-based 0402 and 0603 thin-film resistors show how mounting, heat flow, and low parasitics must work together in compact RF systems.
The arrival of a 0201 option in an RF-focused C0G MLCC family highlights the tradeoffs among size, Q, ESR, resonance, assembly, and repeatability.
A new grid-to-core collaboration shows how solid-state transformers, SiC, GaN, and supercapacitors could reshape AI data-center power resilience.
How the dispute behind the first practical battery still informs capacitor selection, power integrity, reliability testing, and supply-chain qualification.
How a 1996 power metal strip resistor concept became a lasting lesson in current sensing, thermal design, sourcing, and power-system reliability.
A reliable 24V input coordinates MOSFETs, diodes, TVS devices and capacitors to manage reverse polarity, surge energy and inrush current.
