1110-270K-RC Description

Short technical summary and product information.

The Bourns 1110-270K-RC is a fixed inductor from the 1110 series, featuring a drum core wirewound construction with a ferrite core. It offers an inductance of 27 µH with a tolerance of ±10% and a maximum DC resistance of 30 mOhm. The component is rated for a DC current of 4.5 A, defined as the current causing a 50°C temperature rise and 5% inductance drop. It is unshielded and designed for through-hole mounting in a radial package. The operating temperature range is -55°C to 105°C. The inductor has a diameter of 16.76 mm and a height of 21.34 mm. It features self-leaded terminations and is RoHS compliant. Typical applications include power supply filtering, DC-DC converters, and high current choke circuits where low DCR and high current capacity are required.
