LSF/HSF - Series filters

N4L LSF Filters are passive low pass filters specifically designed for use with the N4L range of HF current shunts, or other applications where attenuation of high frequency noise is desirable.

Available as 5 kHz low pass and 50 kHz low pass for improved signal to noise ratio, these compact filters are fitted with safety BNC connectors to enable direct connection to the PPA external inputs.

The HSF10m filter has been designed for DC blocking and is designed to be used in pairs with early revision levels of our BATT470m accessory for EIS (Electrochemical Impedance Spectroscopy)
