Procurement Notes
Verify compliance requirements carefully as this specific part number contains lead. Confirm that the target application permits leaded components due to RoHS non-compliance. Ensure the surface mount footprint matches the rectangular package dimensions specified in the official datasheet before finalizing procurement orders to prevent assembly errors.
Selection Notes
Select this component when a shielded toroidal inductor is required for power applications. Consider the 1.5 A current rating and 145 mΩ resistance for efficiency calculations. Evaluate the 6 MHz self-resonant frequency against circuit switching speeds. Compare against other KMSM series variants if different inductance values or physical sizes are needed for the design.
Part Context
This component belongs to the KMSM series of wirewound toroidal inductors produced by Gowanda Electronics. The series offers various inductance values and current ratings tailored for COTS+ applications. Gowanda specializes in high-performance magnetic components for aerospace, defense, and medical sectors, providing both standard and custom designs with rigorous quality certifications.
Replacement Considerations
Cross-reference with other KMSM series parts such as 030KM7502SM or 030KM1503SM for alternative inductance values. Verify that substitute components maintain compatible saturation current and DCR specifications. Ensure any replacement also meets the required surface mount package constraints and thermal performance limits.
