10M301K

Overview

The 10M301K is a fixed inductor manufactured by Gowanda Electronics, classified as an unshielded wirewound component with axial leads. It features a nominal inductance of 3 µH and a maximum DC resistance of 700 mOhm. The device supports a maximum current rating of 299 mA and operates within a temperature range from -55°C to 105°C. Weighing approximately 0.3 grams, it is designed for high-frequency applications requiring reliable magnetic performance without shielding interference.

Feature Summary

• Unshielded wirewound construction suitable for RF applications
• Axial lead configuration for through-hole mounting
• High-temperature stability up to 105°C

Applications

• Aerospace electronic systems
• Defense communication equipment
• Medical instrumentation circuits

Procurement Notes

Verify the specific ordering suffix against official Gowanda documentation to ensure correct tolerance and termination specifications. Confirm that the axial lead form factor matches the target PCB layout requirements. Cross-reference the 700 mOhm DC resistance limit with circuit design constraints to prevent excessive voltage drop or thermal issues during operation.

Selection Notes

Select this component when a 3 µH inductance value is required for high-frequency signal processing. The unshielded design necessitates careful placement to avoid magnetic coupling with adjacent sensitive components. Ensure the operating environment remains within the specified -55°C to 105°C range to maintain inductance stability and material integrity over the product lifecycle.

Part Context

This part belongs to the 10M series of molded unshielded RF coils produced by Gowanda Electronics. The series is engineered for demanding environments including aerospace, defense, and medical sectors. These components prioritize reliability and consistent electrical characteristics under varying thermal conditions, distinguishing them from standard commercial-grade inductors.

Replacement Considerations

Direct substitutes include the 10M331K (3.3 µH) and 10M821K (8.2 µH) from the same manufacturer family. Verify that alternative values meet the specific circuit impedance requirements before substitution.
