BC547 NPN Bipolar Junction Transistor from China
The BC547 is a general-purpose NPN bipolar junction transistor designed for low to medium power amplification and switching applications in audio circuits and signal processing. It operates at frequencies below 30 MHz with a maximum transition frequency (fT) of 300 MHz but typically used in low-frequency ranges under 30 MHz. Classified under HTS 8541.29.00.55 as a non-photosensitive transistor with operating frequency less than 30 MHz.

Import Tips
• Verify transistor specifications including fT and operating frequency <30 MHz via manufacturer datasheet for accurate HTS classification
• Include detailed technical datasheets and component markings in import documentation to avoid misclassification as higher frequency devices
• Check for RoHS compliance certification as required for electronic components entering the US market
