Bourns 1120 Series High Current Chokes
Bourns 1120 Series High Current Chokes feature a 0.8A to 11.4A current range and 1μH to 2200μH (±20% and ±10% at 1kHz) inductance range. These chokes provide very high current capacity and low DCR. The 1120 high-current chokes are integrated with epoxy-coated ferrite bobbin core and VW-1 rated shrink tubing to cover winding. These chokes offer a dielectric withstanding voltage of 2500VRMS from the terminal to the shrink tube cover and 1000VRMS from the terminal to the core. The 1120 high-current chokes are self-leaded and RoHS compliant.
