Overview
The Delevan 103R-272K is a fixed surface-mount RF inductor with an inductance of 2.7 µH and a tolerance of 10%. It features a maximum DC resistance of 1.15 Ohms and a rated current of 290 mA. The component utilizes a phenolic core within a rectangular, non-standard package measuring 2.54 mm in length, 1.01 mm in width, and 1.91 mm in height. It operates between -55 °C and 125 °C and contains two terminals.
Feature Summary
- Designed for radio frequency applications as a general-purpose inductor
- Utilizes a phenolic core material for stable performance
- Constructed in a rectangular chip form factor for surface mount technology
Applications
- RF circuit filtering
- Signal processing networks
- General purpose inductive components in electronic assemblies
Procurement Notes
Verify the specific manufacturer designation API Delevan when sourcing this component to ensure authenticity. Confirm that the ordering suffix matches the required electrical parameters, particularly the 2.7 µH inductance value and 10% tolerance. Ensure the procurement documentation explicitly references the 1.15 Ohm maximum DC resistance specification to avoid substitution errors with similar series parts.
Selection Notes
Select this component for designs requiring a compact 2.7 µH inductor with a 290 mA current rating. The rectangular package dimensions are suitable for space-constrained PCB layouts. Verify that the operating temperature range of -55 °C to 125 °C aligns with the environmental conditions of the target application before finalizing the design.
Part Context
This part belongs to the 103R series of fixed inductors manufactured by API Delevan. The series includes various inductance values tailored for RF and general-purpose applications. The 103R-272K specifically represents a mid-range inductance option within this lineup, characterized by its unshielded construction and standard two-terminal configuration.
Replacement Considerations
The 103-272K is a confirmed substitute part number for the 103R-272K. Both variants share identical electrical specifications, including the 2.7 µH inductance and 1.15 Ohm DC resistance. Verify physical package compatibility during replacement to ensure proper mounting on the target PCB.
