1️⃣ High price, low performance. Most off‑the‑shelf chokes cost > $3 each and still fail at > 100 MHz, forcing redesigns.
2️⃣ Inconsistent quality. Batch‑to‑batch variation leads to 12 % return rates in medical device production.
3️⃣ Long lead times. Overseas suppliers often need 6‑8 weeks, delaying product launches and hurting market share.
4️⃣ Regulatory headaches. Non‑compliant parts trigger FCC/UL re‑testing, adding $15 k per project.
5️⃣ Limited customization. Standard sizes cannot fit tight PCB footprints in high‑speed chargers.
Result: Higher total cost of ownership, slower time‑to‑market, and jeopardized brand reputation.
