Instructions:

1. Handling Precautions: The 2N3904 is sensitive to electrostatic discharge (ESD). Use proper ESD protection when handling.
2. Mounting: Ensure the transistor is securely mounted with adequate heat sinking if operating near maximum power dissipation.
3. Biasing: Proper biasing is crucial to ensure reliable operation. Refer to application notes for detailed biasing circuits.
4. Storage: Store in a dry, cool place away from direct sunlight.
5. Soldering: Use a low-wattage soldering iron and avoid excessive heat during soldering to prevent damage.
6. Testing: Before installing into a circuit, test the transistor using a multimeter or transistor tester to ensure it meets specifications.
