AC-DC power filters for EMC and surge compliance
CUI has launched two AC-DC power filters for low power embedded power supplies.

The EMC‑20 and EMC‑30 series offer 20 dB and 30 dB of AC-line noise filtering at 150 kHz to 1 GHz, respectively. Available in compact board mount, chassis mount, and DIN rail configurations, the models ensure surge compliance to the IEC/EN61000-4-5 standard and reduce conducted and radiated emissions to help designs comply with CISPR22/EN55022 Class B limits. 

The EMC filters further feature a wide input voltage range from 85 to 305 Vac and accept up to 1.5 A of nominal input current. A 2,000 Vac isolation voltage and wide operating temperature range from -40 to +85°C affords additional ruggedness in harsh environments. These ac-dc power filters ultimately provide engineers with a convenient modular solution for addressing EMC and surge challenges, while reducing the need for additional external components.

The EMC‑20 and EMC‑30 series are available immediately with prices starting at $6.95 per unit at 500 pieces through distribution.
