Overview
The Delevan 105R-151M is a fixed power inductor featuring an unshielded nonstandard two-lead design. It provides an inductance of 150 nH with a tolerance of ±20%. The component supports a maximum DC current of 775 mA and exhibits a maximum DC resistance of 160 mOhms. This surface-mount compatible device utilizes a ferrite core and is suitable for high-frequency power applications requiring compact form factors.
Feature Summary
- Unshielded construction minimizes magnetic interference with adjacent components
- Nonstandard two-lead configuration allows flexible PCB routing
- Ferrite core material ensures stable performance at high frequencies
Applications
- High-frequency power supply filtering
- DC-DC converter input/output stages
- RF signal chokes in compact electronics
Procurement Notes
Verify the exact lead configuration and footprint dimensions against your PCB layout, as the nonstandard package may require custom pads. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the 775 mA current rating meets your circuit's peak load requirements to prevent saturation.
Selection Notes
Select this component when low inductance values are required for high-speed switching applications. The unshielded design is ideal for layouts where magnetic field directionality can be managed. Compare the 160 mOhm DCR against efficiency targets to ensure minimal voltage drop across the inductor during operation.
Part Context
This part belongs to the Delevan 105R series of fixed power inductors. The series offers various inductance values tailored for different power management needs. The 105R-151M specifically addresses applications needing nanohenry-level inductance with moderate current handling capabilities in a small footprint.
Replacement Considerations
Check for direct substitutes within the 105R series with similar inductance and current ratings. Verify that any replacement maintains the same nonstandard lead spacing and unshielded characteristics to fit existing board designs without modification.
