030KM2003SM

Overview

The 030KM2003SM is a shielded wirewound toroidal inductor from Gowanda Electronics, designed for demanding RF and power applications. It features an inductance of 200 µH with a maximum DC resistance of 300 mOhm and a current rating of 1.04 A. The component operates within a temperature range of -55°C to 130°C and exhibits a self-resonant frequency of 2 MHz. Packaged in tape and reel format, it supports surface mount integration for compact circuit designs.

Feature Summary

• Shielded toroidal construction minimizes electromagnetic interference
• Wirewound design ensures stable performance under load
• Surface mount configuration facilitates automated assembly

Applications

• Broadband power RF transformer circuits
• Industrial filtering systems
• Medical imaging equipment components

Procurement Notes

Verify the specific ordering suffix against official Gowanda documentation to confirm package type and lead-free status. Ensure compatibility with surface mount reflow profiles. Confirm that the 1.04 A current rating meets system requirements. Check for RoHS compliance if required by project specifications. Validate the 200 µH inductance value at the specified test frequency.

Selection Notes

Select this component when high Q-factor and low AC losses are critical for RF signal integrity. The shielded design is suitable for dense PCB layouts where magnetic coupling must be contained. Consider the 300 mOhm resistance for efficiency calculations in power paths. Evaluate the 2 MHz self-resonant frequency against operating bandwidth needs.
