rfi suppresion chokes rn series current-compensated chokes rated currents from 0.3 to 10a dc to 1khz frequency 100khz to 3mhz common-mode resonance frequency dual-choke con? gurations multiple pcb-mounting options typical applications rn chokes are attenuating common-mode or asymmetric (p/n ?> e) interference signals, by being connected in series with the phase and neutral lines of an ac powerline input. symmetrical components of the noise are also attenuated by the leakage inductance of the windings. these chokes are typically used in conjunction with suppression capacitors. high saturation resistance and excellent thermal behavior. through hole pin connections. dual-choke configuration. small compact design. multiple housing options. custom-specific versions are available on request. phase-angle control circuits in combination with saturating chokes emi input filters for suppressing equipment with no earth connection suppressing high interference levels features and benefits technical specifications maximum continuous operating voltage: 250vac @ 40c operating frequency: dc to 1khz rated currents: 0.3 to 10a @ 40c max. high potential test voltage winding-to-winding @ 25c: 1500vac, 60 sec, guaranteed 1500v, 50hz, 2 sec, factory test winding-to-housing @ 25c: 4000vac, 60 sec, guaranteed surge current @ 10msec: 20 x i nominal @ 25c temperature range (operation and storage): -40c to +125c (40/125/56) flammability corresponding to: ul 94v-0 mtbf @ 40c/230v (mil-hb-217f): > 5,000,000 hours typical electrical schematic approvals
