1. Excessive EMI causing data errors and costly downtime – up to 37% production loss in uncontrolled environments.
2. Oversized, expensive components that inflate BOM and breach weight limits for compact enclosures.
3. Inconsistent quality across batches, leading to re‑work and warranty claims.
4. Long lead times from overseas suppliers—average 8‑10 weeks—delaying project roll‑out.
5. Regulatory compliance gaps (CE, FCC, RoHS) that stall market entry.
6. Lack of customization for specific frequency ranges (10 kHz‑500 MHz) and current ratings.
What does this mean for you? Higher operational costs, missed deadlines, and reduced competitiveness.
