High precision 1% inductance tolerance
Standard surface mount termination style

Applications

RF circuit design
PCB mounting

Procurement Notes

This component is officially classified as obsolete and is no longer manufactured by API Delevan. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Buyers must confirm the authenticity and condition of any available stock from third-party suppliers, as standard supply chain channels do not support this part number.

Selection Notes

Engineers requiring this specific value should evaluate alternative components due to the discontinued status of the 105R-681F. Selection criteria should prioritize matching the 680 nH inductance, 1% tolerance, and similar physical footprint to ensure compatibility with existing PCB layouts and RF performance requirements.

Part Context

The 105R-681F belongs to the Delevan 105/R series of fixed RF inductors. This series was designed for surface-mount technology applications requiring precise inductance values. The part represents a legacy product line from API Delevan, now superseded by newer manufacturing offerings within the company's portfolio.
