• DC-DC converter input/output stages

Procurement Notes

Verify the specific manufacturer part number against official Murata documentation to confirm electrical parameters. Ensure the procurement source provides valid RoHS compliance data. Cross-reference the package dimensions and lead spacing with the mechanical drawing before finalizing orders to prevent assembly mismatches.

Selection Notes

Select this component when a low-profile radial inductor is required for space-constrained PCB layouts. The 33 µH value suits moderate frequency filtering applications. Verify that the 550 mA current rating meets the circuit's peak and RMS requirements. Consider the unshielded nature for potential EMI constraints in sensitive environments.

Part Context

This component belongs to the 1100R series of power inductors manufactured by Murata Power Solutions. The series offers various inductance values in a standardized radial package format. These inductors are commonly used in consumer electronics and industrial power supplies where cost-effective through-hole solutions are preferred over surface-mount alternatives.

Replacement Considerations

Check for direct substitutes within the 1100R series with matching inductance and current ratings. Verify pin compatibility and physical dimensions before swapping with other manufacturers' radial inductors. Ensure thermal performance remains adequate under load conditions.
