BC849CW-QF

Overview

The BC849CW-QF is an NPN general-purpose transistor manufactured by Nexperia, housed in a SOT323 (SC-70) plastic surface-mount package. It features a maximum collector current of 100 mA and a maximum voltage rating of 45 V. The component is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

AEC-Q101 qualified for automotive reliability
Low current operation suitable for sensitive circuits
Compact SMD plastic package design

Applications

Low noise stages in tape recorders
Hi-fi amplifiers
Audio-frequency equipment

Procurement Notes

Verify the specific suffix 'QF' against official Nexperia documentation to confirm it denotes the correct packaging format or variant. Ensure the part number matches the AEC-Q101 qualification requirements for your target application. Cross-reference with authorized distributors to validate authenticity and supply chain integrity before finalizing procurement decisions.

Selection Notes

Select this component when designing low-noise audio circuits requiring small form factors. It serves as a complement to the BC859W PNP transistor. Consider its 100 mA current limit and 45 V voltage ratings during circuit planning to ensure safe operating margins are maintained within the specified thermal constraints.

Part Context

This device belongs to the BC849 series of NPN general-purpose transistors. It shares the SOT323 package with related parts like the BC846W and BC848B. The product line emphasizes low power consumption and compact size, making it suitable for portable electronics and signal processing tasks where board space is limited.

Replacement Considerations

The BC859W is the documented PNP complement. For direct substitution, verify pinout compatibility and electrical parameters such as hFE gain ranges and saturation voltages against the original design specifications.
