Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to confirm the packing method, as the 'TA' designation indicates Ammo Pack delivery. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as historical data varies. Ensure the procurement channel is an authorized source to guarantee genuine parts and full traceability, mitigating risks associated with counterfeit components.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage NPN transistor is required for low-noise amplification. The B classification provides a guaranteed minimum hFE of 200, ensuring consistent gain across units. Consider the TO-92 package constraints regarding thermal dissipation and physical space. Verify that the 65 V rating aligns with the maximum operating voltages in the target circuit design.
