The Name "Silicon Resistor" Left Me Staring at the Selection Table for Half a Minute

Let me bring something up. Last week I was looking up this silicon resistor from Langxi Technology. I typed three characters into the search box, and the results spanned three industries.

Half the results were about four-point probe measurement of sheet resistance and resistivity on silicon wafers — the setup where probes press onto the sample, pass a constant current, and read the voltage drop. Half were about metal silicon resistors in EV pre-charge circuits, with continuous rated temperature up to 350°C, a hundred degrees higher than ceramic. And there were a bunch of silicon-based thermistors that feed straight into an ADC with a voltage divider. All three things are called "silicon resistor" in the BOM.

From where I sit, the sticking point is the interface. You say "silicon resistor" to someone, and they assume you mean silicon wafer resistivity testing; then it turns out you actually need a power device that withstands surges, and two pages into the datasheet nothing matches. Non-standard naming means every downstream step has to bear the consequences.

So the judgment is straightforward: the things themselves are usable, but before selection you have to write out the full name — is it a silicon-based thermistor, a metal silicon resistor, or silicon wafer resistivity testing. Anyone who just writes "silicon resistor" and drops it into the BOM — I don't recommend that.
