030KM7502SM

Overview

The Gowanda Electronics 030KM7502SM is a general-purpose surface-mount power inductor featuring a shielded toroidal core. It provides a nominal inductance of 75 µH with a tolerance of 10% and operates at a test frequency of 1 kHz. The component supports a maximum rated current of 1.62 A and exhibits a maximum DC resistance of 0.125 Ω. It has a self-resonant frequency of 7 MHz and functions within an operating temperature range of -55°C to 130°C. The device utilizes a rectangular package with two terminals.

Feature Summary

• Shielded toroidal construction minimizes electromagnetic interference for precise inductance performance.
• Surface-mount design facilitates automated assembly and compact circuit board integration.
• Wide operational temperature range ensures reliability across extreme environmental conditions.

Applications

• Power supply filtering circuits
• General-purpose electronic signal processing
• Electromagnetic interference suppression systems

Procurement Notes

Verify compliance requirements as the standard 030KM7502SM variant contains lead and does not meet RoHS standards. Confirm that the specific application environment accommodates non-RoHS components or select the LF suffix variant if regulatory compliance is mandatory. Ensure surface-mount footprint compatibility during procurement planning.

Selection Notes

Select this component when a shielded toroidal inductor with 75 µH inductance and 1.62 A current rating is required for surface-mount applications. Consider the 030KM7502SMLF variant if RoHS compliance is necessary, noting that suffix changes may affect availability but not electrical function. Evaluate thermal management needs given the 130°C maximum operating temperature limit.

Part Context

This part belongs to the KMSM series of traditional surface-mount power inductors from Gowanda Electronics. The series offers various inductance values ranging from 10 µH to 250 µH, all sharing similar physical dimensions and shielding characteristics. The 030KM7502SM represents a mid-range inductance option within this standardized product line designed for robust power applications.

Replacement Considerations

The 030KM7502SMLF serves as a direct functional substitute, offering identical electrical specifications while providing RoHS compliance. Other KMSM series variants differ only in inductance values and require circuit re-evaluation. No alternative manufacturers are explicitly documented as direct replacements in official Gowanda documentation.
