Leakage current (cold) =0.1ma A 242V.
Isolation (cold) =5ml Ohms minimum to 500V
Dielectric strength 1500v 1/seg.
Length tolerance +/- 1.5%
Diameter tolerance -0.00079 to -0.00236 mm
Connection tolerance +/-15mm
Power tolerance (w) +5%/-10%
Cold zone depending length and diameter around 0.197-0.591mm
