Schaffner EMC Extends Inlet Filter Series With Increased Attenuation Performance

Schaffner EMC announced that it has extended its FN9222 inlet filter series to include the new FN9222E, which features an earth line choke for applications requiring greater attenuation performance or additional attenuation on the ground wire.

Offering an increased attenuation, the FN9222E is suitable for use in a variety of applications in the electrical, household appliance, test and measurement, power supply and electric data processing industries. In addition, the filter’s low leakage current option (B-type) makes it suitable for use in medical applications. A wide range of amperage ratings and a variety of mounting styles allows for application specific selection and deployment.

With new technologies for power supplies demanding better EMI filter performance, the compact FN9222E delivers a broader performance range than Schaffner’s existing IEC inlet filters, while being mechanically compatible with the panel cut-out of traditional filters. The new model offers what is described as exceptional conducted attenuation performance based on chokes with high saturation resistance and excellent thermal behavior.

The FN9222 and FN9222E is said to provide maximum installation flexibility. Each filter features traditional screw mounting with a time saving snap-in option available for simplified installation. In addition, extra wide mounting flanges (U-types) are also available.

The filters are suitable for a maximum continuous operating voltage of 250 Vac, 50/60 Hz, an operating frequency of dc to 400 Hz and a temperature range of -25 to +85°C (25/85/21). The series also meets UL, CSA, ENEC, and CQC safety standards. The FN9222 has a current ratings of 1 A to 20 A at 50°C, while the FN9222E offers a current ratings of 1 A to 15 A at 50°C.

Low quantity pricing for the FN9222E starts at less than $7.00. Delivery is 2 weeks ARO.
