Applications
- RF signal filtering circuits
- Impedance matching networks
- Radio frequency choke applications
Procurement Notes
Verify the manufacturer designation carefully, as some listings associate this part number with API Delev or All Sensors due to corporate history. Confirm RoHS compliance status through official datasheets, as conflicting records exist regarding environmental compliance. Ensure the specific suffix matches the required tolerance and resistance parameters before finalizing procurement orders.
Selection Notes
Select this component when an unshielded RF inductor is required to minimize magnetic interference coupling in sensitive designs. The 1.5 uH value and 115 MHz self-resonant frequency make it suitable for mid-range RF frequencies. Consider the 340 mA current limit and 840 mOhm resistance for power loss calculations in the target application circuit.
Part Context
This component belongs to the 103/R series of fixed RF inductors manufactured by Delevan. The series provides various inductance values within a consistent 103 package size (2.5x2.5mm). These inductors are engineered for high-frequency stability and are commonly used in wireless communication devices and RF transceivers requiring precise inductive elements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 1.5 uH inductance, 3% tolerance, 840 mOhm DCR, and 103 package dimensions with other manufacturers' unshielded RF inductor catalogs.
