Filtered inlets raise attenuation levels

Additional ranges of IEC inlet filter modules are developed for applications requiring high attenuation performance or additional attenuation on the earth line.

Schaffner has launched three new ranges of IEC inlet filter modules.

The FN 9222E, FN 9233 and FN 9233E have been added to the proven FN 9222 filter range.

They have been developed for applications requiring high attenuation performance or additional attenuation on the earth line.

The FN 9233 and FN 9233E IEC inlet filter modules have been developed for systems or switching power supply units that require a high level of interference suppression.

Compared with the standard FN 9222 filter family, the new FN 9233 series offers higher symmetrical and asymmetrical attenuation performance.

The FN 9222E and FN 9233E IEC inlet filters also include an earth line choke, for applications requiring the reduction of interference signals on the earth line.

All the new filters are designed for a maximum continuous operating voltage of 250V AC, 50/60Hz, as well as for rated currents from 1 to 10A (ENEC) and 1 to 15A (UL, CSA, CQC).

In addition to the standard version, there is also a safety version available or a medical version with low leakage currents.

These new products series are offered with a variety of mechanical mountings and hot inlet versions (C16).

The filters comply with the RoHS Directive.

Paul Dixon, Managing Director of Schaffner comments: "IEC filter connectors are widely used with portable products and where country specific power cords may be required".

"Integrating the IEC connector and EMC filter not only reduces the component count and cost but also assists the system designer to gain EMC approvals".

"The new FN 9233 offers up to 6dB more attenuation than our existing FN 9222 in the same package sise".

"These new IEC filtered connectors provide a safe, high quality mains connection and filter solution".

The new FN 9222E, FN 9233 and FN 9233E mains inlet filters are available direct from Schaffner and a number of global distribution sources.

Typical applications include electrical and electronic equipment, consumer goods, test and measurement equipment, rack mounted systems, electronic data processing and point of sale systems, office automation and datacomms equipment.
