030KM2502SM

Overview

The 030KM2502SM is a surface-mount power inductor manufactured by Gowanda Electronics. It features a nominal inductance of 25 µH with a tolerance of ±10%. The component has a maximum DC resistance of 70 mΩ and a saturation current rating ranging from 500 mA to 960 mA. Its self-resonant frequency is specified at 25 MHz. The device operates within a temperature range of -55°C to 130°C and utilizes a non-standard rectangular package configuration.

Feature Summary

• Designed as a general-purpose power inductor for surface-mount applications
• Utilizes a shielded toroidal core construction
• Supports high-temperature operation up to 130°C

Applications

• Power supply filtering circuits
• General-purpose electronic signal processing
• Industrial equipment power stages

Procurement Notes

Verify lead times and availability directly with Gowanda Electronics or authorized distributors, as stock levels fluctuate. Confirm RoHS compliance status, noting that some Gowanda KMSM series variants may be traditional lead-compliant rather than fully RoHS compliant depending on the specific suffix. Ensure the ordering part number matches the required electrical parameters and package type before finalizing procurement orders.

Selection Notes

Select this component when a 25 µH inductance value is required for surface-mount power applications. Consider the 70 mΩ DCR and saturation current limits to ensure compatibility with circuit load requirements. Verify that the operating temperature range of -55°C to 130°C meets environmental conditions. Check if the shielded toroidal design fits within available PCB space constraints compared to unshielded alternatives.

Part Context

This part belongs to the KMSM series of standard power inductors produced by Gowanda Electronics. The series offers various inductance values and package sizes tailored for surface-mount technology. Gowanda specializes in components for aerospace, defense, and medical sectors, providing both standard and custom magnetic devices.

Replacement Considerations

The 030KM2502SMLF is a listed variant within the same product family. Verify if the LF (Lead-Free) suffix provides necessary regulatory compliance while maintaining identical electrical specifications. Cross-reference other 030KM series parts only if different inductance values are acceptable.
