103R-273FS

Overview

The Delevan 103R-273FS is a fixed surface-mount power inductor from the 103/R series. It features an unshielded wirewound ferrite core design with a nominal inductance of 27 µH and a tolerance of ±1%. The component supports a maximum DC current of 120 mA and exhibits a maximum DC resistance of 6.9 Ohms. Its physical dimensions are non-standard, measuring approximately 2.79 mm in length, 1.91 mm in height, and 1.91 mm in width. The unit operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Utilizes a wirewound ferrite core construction for stable inductance performance.
• Features an unshielded design suitable for general RF applications.
• Supports high-temperature operation up to 125°C.

Applications

• RF circuit filtering
• Power supply chokes
• Signal processing networks

Procurement Notes

Verify component authenticity through authorized API Delevan channels or certified distributors. Confirm RoHS3 compliance status and check for specific lot traceability requirements. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering.

Selection Notes

Select this component when a 27 µH inductance with low current handling is required. The 6.9 Ohm DC resistance limits suitability for high-current paths. Verify PCB footprint compatibility due to the non-standard package dimensions.

Part Context
