Schurter expands IEC filtered inlet range to counter interference

Schurter has expanded its IEC filtered inlet range to include the latest 5124 series, which achieves a higher attenuation than earlier series 5120 and 5123. The enhanced filter performance is achieved by incorporating the latest in high-performance components while maintaining the same package dimensions.

The 5124 series is equipped with exclusive chokes that have high-permeable toroidal cores and an inductance significantly higher than that of the earlier series. The increased inductance achieves a 10 dB improvement in attenuation of asymmetrical interference signals. The enlarged X-capacitors help counter symmetrical interference. Available in screw or snap-in mounting the metal flange and snap-arms make excellent contact with the chassis when mounted, which further optimises filtering and shielding effects. 

The 5124 complements the 5120 and 5123 series by filling attenuation requirements where the other two have gaps. Despite the significantly larger components, the 5124 retains the same dimensions as its predecessors, which allows for interchangeability between series depending on application specific areas of attenuation required over the range of frequency to 400 MHz. The 5120, 5123 and 5124 series are available with operating currents 1-10 A according to IEC and 1 -15 A according to UL in standard or medical low leakage versions. Rated voltage is 250 VAC. The series are V-Lock power cord compatible and ENEC, CQC as well as cURus approved. 

The expansion of electronics equipment places higher demands on interference suppression for safe and reliable equipment operation. The new 5124 is designed to meet such demands and is suitable in areas of high equipment concentration, such as those found in medical, test & measurement and industrial automation.
