8. Y. Chung and N. Ofek (personal communication). The capacitance of the pseudopowder filter depends on how thick the insulating Formvar around the copper line is. We used standard commercial copper wires covered by Formvar as an inner conductor of the filter. The thickness of the Formvar of the wire is 0.05-0.1 mm. In this case, the filter has typically 1-2 nF/m capacitance between the signal line and the ground line.
