Schaffner's New Earth Line Choke IEC

Schaffner EMC, a leading provider of EMI/RFI components and solutions for power quality, has extended is FN9233 inlet filter series to include the new FN9233E featuring an earth line choke with approximately 6dB more attenuation compared to the FN9222 family. The series is ideal for applications requiring greater attenuation performance or additional attenuation on the ground wire.

The FN9233E offers exceptional conducted attenuation performance with inductors based on a high saturation resistance and excellent thermal behavior. In addition, the filter's earth line choke helps to reduce interference signals on the ground wire.

With a high symmetrical and asymmetrical attenuation performance, the FN9233E was developed for devices and switching power supply units that require a high level of interference suppression such as in electrical, test and measurement, office automation and datacom equipment applications.

Integrated RF shielding technology

RF Micro Devices' patent pending MicroShield Integrated RF Shielding technology eliminates the need for bulky and costly external shields by integrating RF shielding directly into the RF IC or module. In doing so, it can reduce the height and volume requirements for RF sections by up to 25% and 50%, respectively, and provides customers with components that are insensitive to board placement.

MicroShield technology reduces the impact of EMI and RFI by minimising exposure to external fields and preventing energy leakage into unwanted areas of the host device. Also, by eliminating sensitivity to board placement, it eliminates the risk of circuit retuning, thereby accelerating time-to-market and reducing the cost of RF implementation.
