Powerful factory, quality assurance, OEM/ODM design, high‑speed delivery. Tailored for corporate purchasing managers, technical directors, and operations leaders who demand reliable electromagnetic compatibility (EMC) solutions.
1. High price, low performance. Many off‑the‑shelf common mode EMI filters cost 30% more yet deliver only 10‑15 dB attenuation at 150 kHz.
2. Inconsistent quality. Uncertified suppliers often ship units with poor solder joints, leading to 20‑30 % field failure rates.
3. Long lead times. Standard inventory models can take 8‑12 weeks, delaying product launches and incurring penalty fees.
4. Regulatory gaps. Without CE, FCC, or RoHS compliance, your shipment may be detained at customs, adding $5‑10 k per incident.
5. Limited customization. One‑size‑fits‑all filters cannot address high‑frequency (>1 MHz) noise in new‑energy converters.
| Parameter | Typical Value | Unit | Compliance |
|---|---|---|---|
| Insertion Loss (150 kHz) | ≥ 35 | dB | FCC, CE |
| Frequency Range | 150 kHz – 5 MHz | – | IEC‑61000‑4‑6 |
| Max Current | 15 | A | UL‑60730 |
| Operating Temperature | ‑40 ~ +85 | °C | ISO 9001 |
| Certification | CE, FCC, RoHS, CB, VDE | – | All major markets |
