EMI input filters in series with the phase and neutral lines Dual, triple and quad-choke For suppressing equipment with no earth of an AC powerline input. Symmetrical configuration. connection components of the noise are also Up to 64A quad configuration. Suppressing high interference levels attenuated by the leakage inductance of the windings. These chokes are typically Multiple housing options. used in conjunction with suppression Custom-specific versions are available capacitors. on request.EMC/EMI Chokes > RD series Choke selection table Choke Nominal current Inductance Resistance Choke Input/Output Pin footprint Weight 40C L R configuration connections connections A mH/path m/path Qty mm g RD 5122-6-9m6 6 9.6 52.55 2 -02 1 160 RD 5122-10-6m0 10 6 24.25 2 -02 1.3 160 RD 5122-16-2m0 16 2 9.5 2 -02 1.6 160 RD 5132-6-5m0 6 5 38 3 -02 1 160 RD 5132-10-3m0 10 3 17.6 3 -02 1.3 160 RD 5132-16-1m0 16 1 6.9 3 -02 1.6 160 RD 6127-6-15m0 6 15 66.65 2 -07 1 235 RD 6127-10-9m0 10 9 25.9 2 -07 1.5 235 RD 6127-16-3m0 16 3 10.9 2 -07 1.8 235 RD 6137-6-7m5 6 7.5 49 3 -07 1 235 RD 6137-10-4m5 10 4.5 18.35 3 -07 1.5 235 RD 6137-16-1m5 16 1.5 8.3 3 -07 1.8 235 RD 7127-6-25m0 6 25 84.2 2 -07 1 320 RD 7127-10-14m0 10 14 33.5 2 -07 1.4 350 RD 7127-16-5m7 16 5.7 14.1 2 -07 1.8 370 RD 7127-25-2m8 25 2.8 6.4 2 -07 2.4 400 RD 7127-36-1m0 36 1 3.3 2 -07 2.7 380 RD 7137-6-12m0 6 12 60.6 3 -07 1 340 RD 7137-10-6m6 10 6.6 21.9 3 -07 1.5 380 RD 7137-16-2m8 16 2.8 10.7 3 -07 1.8 380 RD 7137-25-1m3 25 1.3 4.45 3 -07 2.5 440 RD 7137-36-0m5 36 0.5 2.75 3 -07 2.7 400 RD 7147-6-6m0 6 6 45.1 4 -07 1 320 RD 7147-10-3m5 10 3.5 19.1 4 -07 1.4 370 RD 7147-16-1m5 16 1.5 8.5 4 -07 1.8 390 RD 7147-25-0m7 25 0.7 3.65 4 -07 2.4 430 RD 7147-36-0m2 36 0.2 2.3 4 -07 2.5 400 RD 8127-16-12m0 16 12 20.05 2 -07 2 590 RD 8127-25-5m0 25 5 8.45 2 -07 2.4 630 RD 8127-36-3m0 36 3 4.55 2 -07 1.5 x 4.5 690 RD 8127-50-1m0 50 1 2.5 2 -07 1.7 x 5 640 RD 8127-64-0m8 64 0.8 1.6 2 -07 2.5 x 5 710 RD 8137-16-5m0 16 5 11.6 3 -07 2 630 RD 8137-25-2m5 25 2.5 6.4 3 -07 2.4 650 RD 8137-36-1m5 36 1.5 3.65 3 -07 1.5 x 4.5 720 RD 8137-50-0m6 50 0.6 2.15 3 -07 1.7 x 5 700 RD 8137-64-0m5 64 0.5 1.35 3 -07 2.5 x 5 780 RD 8147-16-3m0 16 3 9.25 4 -07 2 650 RD 8147-25-1m3 25 1.3 5.05 4 -07 2.4 650 RD 8147-36-0m8 36 0.8 3 4 -07 1.5 x 4.5 760 RD 8147-50-0m3 50 0.3 1.75 4 -07 1.7 x 5 740 RD 8147-64-0m2 64 0.2 1.1 4 -07 2.5 x 5 820 Test conditions: Measuring frequency: 1kHz 500A > 0.16mH > 1.6mH 50A > 1.6mH < 160mH Inductance tolerance: +50%, -30% Resistance tolerance: max. 15% 25C 200m, 100mA Electrical characteristics 25C: 2C
