3 appr ovals where indicated s power feed through filters f.ll.cc series p ower feed through capacitor filters enable a consistently high f requency performance to be combined with high current capability, compact mechanical enclosures and terminations which suit use in many industrial applications such as telecommunications, medical equipment and dc power systems.t hese filters are mechanically robust to withstand use under normal h igh current applications and yet sufficiently compact to enable system integration. under ac use consideration must be given to the leakage current caused by the capacitance value in order to ensure compliance with equipment safety specifications. likewise under ac or dc use the safe discharge after use must be considered because of the substantial energy which can be stored. the construction is designed so that multiple high frequency resonances are minimised and hence the performance is maintained over the operating frequency range. these products avoid this weakness so often demonstrated in many commercially available products. the dielectric construction of the capacitor elements means that they have high level voltage withstand capability and can cope with rapid transients. these products are fully encapsulated in a flame retardant v0 to ul 94 polyurethane resin system. mec hanical specifications manufacture: metal case sealed with plastic cover; mounted via bracket (025a.015.i0 & 025a.055.i0) or metric nut (see table for sizes). connections: thr eaded bar with metric nut Csee table for sizes. electrical specifications rated voltage (v r ): see table rated current (i r ): referred to room temperature = 40 voltage test (2 s .): see table climatic category: gpc (40/085/56); temperature range: -40c to +85c s code max values c voltage dimensions (mm) dia insertion i r v r test loss dc dc/ac (uf) (dc) a b c d t d graph 025a.015.i0 25 100/- 0.1 250 n/a 46 57 25.4 n/a m5 plot 1 025a.055.i0 25 100/- 0.5 250 n/a 46 57 25.4 n/a m5 plot 2 075a.400.i0 75 -/250 4 1200 13 45 99 30 m20x1 m6 plot 5 100a.015.i9 100 100/- 0.1 500 13 45 111 30 m20x1 m8 plot 1 200a.016.i2h 200 1000/- 1 2500 15 31 93 55 m27x1.5 m8 plot 3 200a.036.i0 200 60/- 3 500 12 36 99.5 38 m20x1 m10 plot 4 300a.055.i1 300 750/- 0.5 3950 15 50 152 55 m32x1.5 m12 plot 2 500a.055.i1 500 750/- 0.5 3950 15 80 220 55 m32x1.5 m20 plot 2 800a.055.i1 800 750/- 0.5 3950 15 80 250 55 m36x1.5 m25 plot 2 filter range - f.ll.cc.
