Bourns 1130 Series High-Current Chokes

Bourns 1130 Series High-Current Chokes provide a very high current capacity (1A to 21A) and low DC resistance (DCR). The 1130 series features an epoxy-coated ferrite bobbin core and VW-1-rated heat shrink tubing to cover winding. These Bourns chokes have a dielectric withstanding voltage of 2500VRMS from the terminal to the shrink tube cover and 1000VRMS from the terminal to the core.
