* NFA31G is a 4-circuit noise filter in 3.2x1.6mm size with 0.8mm pitch. High density mounting is available. * 3-terminal structure enables excellent high frequency performance. * Distributed constant circuit realizes smooth change of impedance which prevents reflection of signal and distortion of wave shape. * NFA31G series is effective in lines where ground is not stable, because the resistance element in the filter absorbs noise and returns it to ground line
