Low Pass Filters for DC Looms​ Oxford Instruments offer a selection of low pass multi-stage filters for our 24 way DC looms.​The low pass filters are available in four different cut-off frequencies and are compatible with our dilution refrigerators.​​ These can either be fitted in the factory with the system, or can be purchased separately, or as an upgrade to your current system. The filter is constructed in a gold plated copper chassis with RF gaskets to provide screening and thermal dumping for the filter PCB.​ The surface mount filter components are selected to provide excellent value stability over a wide cryogenic temperature range which is demonstrated by the consistency of response between the room temperature and 4K performance.​ Four cut-off frequencies available between 170 Hz and 110 kHz.
