Notes
- SMTSO2515CTJ is not an IC or electronic component — it is a mechanical PCB-mounted threaded standoff/nut for M2.5 threads.
- No "pins" exist in the traditional sense; this component has a single mounting pad for reflow soldering to the PCB and a threaded hole for mechanical fastening.
- The component is designed for reflow soldering only; wave soldering is not applicable.
- Maximum tightening torque must be observed to prevent mechanical damage to the PCB and component.
- The "2515" code indicates M2.5 thread size with a specific length designation.
