It is necessary to use an input line filter in almost every device. At its choosing, you have a possibility to use a filter combined with an input line socket , or a standalone, most often designed for PCB mounting.
Thanks to a big amount of various electric devices with a non-linear power consumption, the line voltage sinusoid is far distant from a clean form found in books of mathematics. Despite still more stringent EMI and EMC regulations, it is necessary to use line filters – also thanks to the fact, that modern digital circuits with a very low power consumption are potentially more sensitive for disturbances. A similar situation is at analog circuits, where more sensitive circuits are used (amplifiers, AD and DA converters, …). A usage of a filter brings two benefits – a better protection of a device from disturbances and also prevents a noise leakage from your device to a mains line.
A novelty in our portfolio is the Schurter 5500.0655.1. line filter for PCB mounting. Advantage of the PCB version is, that it doesn´t require a space on your device´s rear panel. With a maximum current of 6A, it is suitable even for relatively powerful devices. In the Schurter 5500.0xxx datasheet can be found detailed graphs about the filter attenuation in a common, as well as differential mode. For highest demands regarding EMC, it is possible to equip the filter with a metal shield.
