105R-561J

Overview

The Delevan 105R-561J is a fixed surface-mount inductor designed for RF applications. It features an iron core and unshielded construction within a rectangular 1812 package measuring 4.83 mm in length, 3.2 mm in width, and 3.4 mm in height. The component provides a nominal inductance of 0.56 µH with a tolerance of ±5%. It supports a maximum DC current of 460 mA and exhibits a DC resistance of 0.45 Ω. The device operates reliably within a temperature range of -55 °C to +125 °C.

Feature Summary

• Unshielded rectangular construction suitable for general-purpose RF circuits
• Iron core material optimized for specific frequency response characteristics
• RoHS compliant lead-free termination system
