Single Bipolar Transistors Procurement Notes

Verify the specific suffix '116' against the official NXP datasheet to confirm packaging details and tape-and-reel specifications. Ensure the component meets required RoHS compliance standards for the target application environment. Cross-reference pinout configurations with standard TO-92 layouts to prevent installation errors during assembly.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a reliable PNP switch or amplifier with moderate voltage handling. Consider the 45 V collector-emitter breakdown voltage when designing for higher supply rails. Evaluate the thermal characteristics within the TO-92 package constraints for continuous operation scenarios.
