Rules:
- manufacturing_status: Use "active", "obsolete", "nrfnd" (not recommended for new designs), "discontinued", or null
- parameters: Extract technical specs like voltage, current, temperature, etc.
- parameters: Extract technical specs like voltage, current, temperature, etc. and put them into the fields according to the JSON schema. Include units if available.
- prices: Extract pricing tiers with minimum_quantity, price, and currency code
- URLs must be absolute (include https://...)
- If information is not found, use null
- Return ONLY the JSON, no explanation text
For parameters, combine name, value, and unit. The unit should be separate if possible.
- Try to avoid duplicating parameters, if the same parameter is mentioned multiple times, or if it is already used in another field.
- Include only the 1 to 3 most relevant images, such as the main product image or important diagrams. Ignore decorative images, logos, or icons.
