103R-270J

Overview

The Delevan 103R-270J is a fixed surface-mount RF inductor with an inductance of 27 nH and a tolerance of 5%. It features a maximum DC resistance of 114 mOhms and supports a maximum DC current of 925 mA. The component has a self-resonant frequency of 1.625 GHz and a minimum Q factor of 49. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. The device operates within a temperature range of -55 °C to 125 °C.

Feature Summary

• Unshielded construction for standard RF applications
• SMD package design for PCB mounting
• High self-resonant frequency capability

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF inductor tasks

Procurement Notes

Verify the specific suffix 'J' indicates the required 5% tolerance against project specifications. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the nonstandard lead configuration matches the target PCB footprint layout prior to ordering.

Selection Notes

Select this component when a 27 nH value with tight 5% tolerance is required for high-frequency stability. The low DC resistance supports efficient power handling up to 925 mA. Verify that the unshielded design does not cause interference in dense layouts compared to shielded alternatives.

Part Context

This part belongs to the 103/R series of SMD RF inductors manufactured by API Delevan. The series provides various inductance values for radio frequency applications. The 103R-270J specifically offers a compact form factor suitable for space-constrained electronic designs requiring precise inductance control.

Replacement Considerations

The 103-270KS is a related variant with 10% tolerance. Verify if the looser tolerance meets requirements. No other direct substitutes are confirmed in public documentation.
