2. High unit cost inflates BOM. Low‑quality chokes can be up to 3× more expensive over a product lifecycle because of warranty and redesign costs.
3. Long lead‑times stall production schedules. Average supplier lead‑time in China exceeds 45 days, causing 15% missed launch windows for US OEMs.
4. Compliance gaps delay market entry. Without CE, FCC, or RoHS certification, you risk costly redesigns and customs holds.
5. Inflexible designs limit product differentiation. Standard off‑the‑shelf chokes lack the current‑rating or size optimization you need for next‑gen devices.
