1110-181K-RC Description

Short technical summary and product information.

The Bourns 1110-181K-RC is a fixed inductor from the 1110 series, designed for high current applications. It offers an inductance of 180 µH with a tolerance of ±10%, a maximum DC resistance of 217 mΩ, and a rated current of 1.6 A (based on a 50°C temperature rise and 5% inductance drop).

 

The inductor uses a ferrite drum core with wirewound construction and is unshielded. It is housed in a radial through-hole package with self-leaded terminations. The operating temperature range is -55°C to +105°C, and it features a dielectric withstanding voltage of 2500 Vrms from terminal to shrink tube cover and 1000 Vrms from terminal to core.

 

Typical applications include power supply filtering, DC-DC converters, and other circuits requiring high current handling with low DC resistance. The part is RoHS compliant as indicated by the -RC suffix.
