1120-681K is a high current choke inductor from the Bourns 1120 Series, designed for power filtering and noise suppression applications. It features an inductance of 680 µH at 1 kHz with a DC resistance of 0.430 O (±20%) and a rated current of 1.6 A. The component utilizes an epoxy coated ferrite bobbin core with VW-1 rated shrink tubing covering the winding, and offers a dielectric withstanding voltage of 2500 Vrms terminal to shrink tube cover and 1000 Vrms terminal to core. With an operating temperature range of -55°C to +105°C, fixed lead spacing, and a center hole for mechanical mounting, this choke is well-suited for high current power supply filtering and EMI suppression in industrial and commercial electronics.
