The Bourns 1140-4R7M-RC is a high current drum core wirewound fixed inductor from the 1140 series. It offers an inductance of 4.7 µH at 1 kHz with a tolerance of ±20%. This component is designed for high current applications, with a rated current (Irms) of 28.1 A based on a 50°C maximum temperature rise and 5% maximum inductance drop, and a saturation current (Isat) of 80 A.
The inductor features a very low DC resistance (DCR) of 3 mOhm maximum, which minimizes power losses and heat generation. It is constructed with an epoxy coated ferrite bobbin core and is unshielded. The part is housed in a radial, vertical cylinder package with a diameter of 38.10 mm and a height of 26.16 mm. It is designed for through hole mounting with a fixed lead spacing and includes a center hole for mechanical mounting.
The 1140-4R7M-RC is RoHS compliant and operates over a temperature range of -55°C to +105°C. It also features a dielectric withstanding voltage of 2500 Vrms from terminal to shrink tube cover and 1000 Vrms from terminal to core.
