106-273F

Overview

The Delevan 106-273F is a fixed surface-mount RF inductor with a nominal inductance of 27 µH and a tolerance of ±1%. It features a maximum DC resistance of 8 Ohms and a rated current of 105 mA. The component utilizes an iron core construction within a 1611 (1611 metric) package, measuring 4.06 mm in length, 2.92 mm in width, and 1.91 mm in height. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• High precision inductance value for stable RF circuit performance
• Iron core material provides consistent magnetic properties
• Surface mount design facilitates automated PCB assembly

Applications

• RF signal processing circuits
• Impedance matching networks
• Filter applications in radio frequency systems

Procurement Notes

Verify RoHS compliance status as the component may be lead-containing. Confirm availability through authorized distributors, as stock levels fluctuate. Ensure the ordering suffix matches the required tolerance and packaging specifications. Cross-reference datasheets for exact dimensional tolerances before finalizing procurement orders.

Selection Notes

Select this component when a precise 27 µH inductance is required for RF applications. Consider the 105 mA current rating and 8 Ohm DC resistance for power handling limits. The 1611 package size must fit the available PCB footprint. Verify thermal stability requirements against the -55°C to 125°C operating range.

Part Context

This part belongs to the Delevan fixed inductor family designed for general-purpose and RF applications. It shares design characteristics with other series like 4302 and 1008R but differs in package dimensions and specific electrical parameters such as DC resistance and current rating.

Replacement Considerations

The 4302-273F offers similar inductance but has different physical dimensions and higher DC resistance. The 1008R-273J provides comparable inductance with a larger package and different current rating. Verify pin compatibility and thermal performance before substitution.
