Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as the 2SC4400 designation originates from Sanyo Semiconductor. Confirm that the specific suffix -3-TL-E matches the required tape-and-reel packaging format. Ensure the sourcing channel provides documentation confirming the part meets the specified 18V and 0.05A ratings. Cross-reference the datasheet version to confirm the hFE and capacitance values align with your design requirements before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN transistor is required for very high frequency bands with low power consumption constraints. The MCP package suits space-constrained PCB layouts. Verify that the 18V collector-emitter voltage and 0.05A current limits are sufficient for the target circuit. Consider thermal management capabilities given the 0.15W power dissipation limit in the small outline package.
