Datasheet
Datasheet Summary
Powered by GS/AI

The High Current Choke, part number 63K3397, features an inductance of 4.7 mH with a tolerance of ¬±10%. It is designed to handle a rated current of 2A, with a maximum DC resistance of 1.14 ohms. The choke is constructed with an epoxy-coated ferrite bobbin core and includes VW-1 rated shrink tubing for insulation. It has a dielectric withstanding voltage of 2500 Vrms from terminal to shrink tube cover and 1000 Vrms from terminal to core. The operating temperature range is from -55¬8C to +105¬8C. This component is RoHS compliant, making it suitable for environmentally conscious designs. The choke is self-leaded with fixed lead spacing and features a center hole for mechanical mounting.
