11R154C

Overview

The Murata Power Solutions 11R154C is a radial lead power inductor from the 1100R series. It features an unshielded ferrite core construction with a nominal inductance of 150 µH and a tolerance of ±10%. The component supports a maximum RMS current of 300 mA and has a maximum DC resistance of 1.65 ohms. Designed for PCB mounting, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Radial lead configuration for through-hole PCB integration
• Unshielded ferrite core design for general power filtering
• Compact form factor suitable for space-constrained applications

Applications

• General purpose power supply input/output filtering
• DC-DC converter circuitry
• Signal conditioning circuits requiring moderate inductance

Procurement Notes

Verify the specific manufacturer datasheet for the 11R154C to confirm exact thermal derating curves and saturation characteristics. Ensure the selected variant matches the required 150 µH value and 300 mA current rating for your specific circuit design constraints before finalizing procurement.

Selection Notes

Select this component when a low-cost, unshielded radial inductor is sufficient for non-critical EMI suppression. Compare against shielded alternatives if magnetic interference with nearby components is a concern. Verify that the 1.65 ohm DC resistance aligns with your efficiency requirements.

Part Context

This part belongs to the 1100R series of radial lead inductors manufactured by Murata Power Solutions. These components are designed for general electronic applications where cost-effectiveness and standard through-hole mounting are prioritized over high-frequency performance or strict magnetic shielding requirements.

Replacement Considerations

Cross-reference with other 150 µH radial inductors from the same series, such as the 19R154C, noting differences in current handling and physical dimensions. Ensure any substitute maintains compatible lead spacing and terminal compatibility.
