Why Your Current Filters Are Holding You Back
- High purchase price – Most suppliers charge a premium for low‑volume orders, inflating your BOM.
- Inconsistent cutoff frequency – Tolerances beyond ±10 % cause signal distortion and costly re‑work.
- Long lead times – Overseas factories often need 6‑8 weeks, delaying production schedules.
- Regulatory uncertainty – Lack of CE, FCC, RoHS certifications can stall market entry.
- Limited customization – Off‑the‑shelf parts rarely meet specific impedance or temperature‑stability requirements.
Data point: 42 % of U.S. manufacturers reported a 15 % increase in downtime due to filter‑related failures in the last fiscal year.
