When the Substrate Becomes the Heat Sink
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.
AlN-based 0402 and 0603 thin-film resistors show how mounting, heat flow, and low parasitics must work together in compact RF systems.
How a 1996 power metal strip resistor concept became a lasting lesson in current sensing, thermal design, sourcing, and power-system reliability.
