Why Your Supply Chain Struggles with Conventional Transformers

1️⃣ High price points from overseas OEMs inflate your BOM by up to 25 %.

2️⃣ Quality inconsistencies cause 12 % of shipments to fail final‑stage testing, leading to production delays.

3️⃣ Long lead times – average 45 days from order to delivery, jeopardizing tight project schedules.

4️⃣ Insufficient shielding results in EMI spikes that degrade audio clarity by 15 dB.

5️⃣ Regulatory non‑compliance (e.g., CE, FCC, RoHS) forces costly redesigns.
