Procurement Notes
Verify the specific ordering suffix to ensure correct packaging format, as variations exist between reel, cut tape, and MouseReel options. Confirm that the selected variant matches the required resistor values and package dimensions for your specific PCB footprint. Always cross-reference the latest datasheet for any updates to mechanical drawings or electrical characteristics before finalizing procurement orders.
Selection Notes
Select this component when a PNP digital transistor with -50V rating and -100mA current capacity is required in a compact SOT-323 package. Ensure the application demands the specific 2.2kΩ/10kΩ resistor ratio provided by this part number. Verify that the operating temperature range extends to +150°C if high thermal conditions are expected in the target environment.
