The Bourns 1140-181K-RC is a fixed inductor from the 1140 series, designed for high current applications. It offers an inductance of 180µH with ±10% tolerance, measured at 1 kHz. The rated current is 7.8 A, defined by a 50°C maximum temperature rise and 5% maximum inductance drop, with a saturation current of 15.5 A.
This unshielded inductor uses a ferrite core and an epoxy-coated bobbin. Its DC resistance is a maximum of 45 mOhm, contributing to low power loss. The operating temperature range spans -55°C to 105°C. Dielectric withstanding voltage is 2500 Vrms from terminal to shrink tube cover and 1000 Vrms from terminal to core.
The component is supplied in a through hole radial package, measuring 38.10 mm in diameter and 26.16 mm in height. It features self-leaded construction with fixed lead spacing of 1.45 mm. A center hole is provided for mechanical mounting. The inductor is RoHS compliant.
