DATA SHEET Saturating Chokes RI series Saturating Chokes Rated currents from 1.5 to 25 A Approvals & Compliances Up to 500 VAC operating voltage DC to 1 kHz frequency Single or dual-choke configurations Performance indicators RI saturating type chokes change impedance at the moment of switching, and can be used to attenuate differential-mode noise or symmetrical interference as generated in fast switching high current applications. These chokes are typically used in conjunction with suppression capacitors. For optimum attenuation chokes must be connected as close as possible to the semiconductor switching device. Features and Benefits Excellent thermal behavior Through hole or wire connections Single or dual-choke configurations Up to 25 A single configuration Technical Specifications Custom-specific versions are available on request Typical Applications Maximum continuous operating voltage 500 VAC @ 40°C Rated currents 1.5 to 25 A Suppressing high interference levels generated by fast switching circuits and/or winding-to-inserts 2500 V, 50 Hz, 2 sec, factory test DC voltage smoothing Surge current @ 10 msec 20 x IN @ 25°C EMC/EMI filters Temperature range (operation and storage) -25°C to +110°C (25/110/21) Phase angle control circuits Flammability corresponding to UL 94 V-0 Power supplies High potential test voltage Chargers Typical electrical schematic 2 Saturating Chokes Schaffner Group DATA SHEET 10.
