When looking for a 15-meter USB 3.0 extension cable with an integrated circuit (IC) from male to female, consider these features:

1. **Length**: 15 meters, which allows for significant distance between devices.

2. **USB 3.0 Compatibility**: Ensures high data transfer speeds (up to 5 Gbps) and backward compatibility with USB 2.0 devices.

3. **Built-in IC Chip**: Helps maintain signal integrity over longer distances, reducing data loss and improving performance.

4. **Durable Construction**: Look for cables with robust shielding to minimize interference and ensure durability.

5. **Connectors**: Ensure the connectors are gold-plated for better conductivity and corrosion resistance.

Check reviews and specifications to confirm that it meets your needs for data transfer and power delivery.
