Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix RLRM confirms tape and reel packaging containing 2000 units per reel. Confirm RoHS compliance status if required, as standard versions may not be compliant. Ensure the component matches the TO-92 (TO-226) long body package dimensions specified in the datasheet before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when low noise characteristics are critical for the application. The high DC current gain makes it suitable for amplification tasks requiring minimal input drive. Verify that the 45 V collector-emitter voltage rating meets the circuit requirements. Consider thermal management if operating near maximum power dissipation limits.
