Why Your Current Isolation Strategy Is Holding You Back
- High Price, Low Yield: Conventional suppliers charge a 30‑40% premium for “standard” isolation parts, inflating BOM costs.
- Quality Inconsistencies: 12% of US‑based OEMs report failure rates above 5% due to poor winding tolerances and inadequate shielding.
- Long Lead Times: Average delivery from overseas factories exceeds 45 days, delaying product launches.
- Regulatory Gaps: Missing CE, FCC, or UL certifications can stall market entry and trigger costly redesigns.
- Limited Customization: Off‑the‑shelf isolation components rarely match the exact impedance or voltage‑rating needed for niche medical or new‑energy devices.
