Single Bipolar Transistors Procurement Notes

Verify the specific suffix against official Central Semiconductor documentation, as variations may exist between PBFREE and APM PBFREE designations regarding packaging format. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure the ordering quantity aligns with factory minimum order requirements and reel specifications.

Single Bipolar Transistors Selection Notes

Select this component when a standard NPN transistor with moderate voltage handling and low current capability is required. The TO-92 package facilitates easy integration into through-hole printed circuit boards. Consider the hFE binning characteristics if precise gain consistency is critical for the target application circuit design.
