You are an electronics sourcing expert. The attached JSON file lists LCSC component subcategories that need enrichment. Each entry may need:
- A `description`: one concise sentence explaining what components belong in this subcategory
- `examples`: 2–3 representative spec strings showing key parameters (e.g. "100µF 35V 6.3x11mm", "1kΩ ±1% 100mW 0603")

Rules:
- description: one sentence, specific enough to distinguish this subcategory from similar ones
- examples: realistic component specs with the important parameters (value, tolerance, voltage/current rating, package/size) — NO part numbers, NO brand names, NO URLs
- entries with "need_examples": true need both description AND examples
- entries without "need_examples" only need a description (examples already present)
- entries already have "examples" listed — use them as context for the description

Output format: one JSON object per line (NDJSON). Include ONLY the fields you generate:
{"id": 51, "description": "Active and passive sound-producing devices..."}
{"id": 55, "description": "Electrodynamic transducers...", "examples": ["8Ω 0.5W 28mm Round", "4Ω 3W 40x28mm Rectangular"]}

Output NOTHING except the NDJSON lines. No markdown, no commentary, no code fences.
Process every entry in the file.
