15M121J

Overview

The 15M121J is a fixed inductor manufactured by Gowanda Electronics, classified as a molded unshielded RF coil with axial leads. It features an inductance of 1.2 µH and a tolerance of ±5%. The component has a maximum DC resistance of 420 mOhm and a rated current of 650 mA. Designed for surface mounting via through-hole technology, it operates within a temperature range of -55°C to 125°C.

Feature Summary

• Molded construction provides mechanical stability and environmental protection for the internal winding.
• Unshielded design allows for flexible placement in circuit layouts without magnetic interference constraints.
• Axial lead configuration facilitates standard through-hole PCB assembly processes.

Applications

• Radio frequency signal processing circuits
• High-frequency filtering applications
• General purpose electronic assemblies requiring axial inductors

Procurement Notes

Verify the specific suffix requirements against the official Gowanda datasheet to ensure correct tolerance and packaging specifications. Confirm that the axial lead form factor matches the target PCB footprint. Check for RoHS compliance status if required by the end-product regulations. Ensure the operating temperature range meets the environmental conditions of the final application.

Selection Notes

Select this component when a 1.2 µH inductance value is required with high reliability in a compact axial package. Consider the unshielded nature for applications where magnetic coupling with nearby components must be minimized or managed by layout. Evaluate the 650 mA current rating against the peak and RMS currents of the circuit to prevent saturation or overheating.

Part Context

This part belongs to Gowanda's line of molded unshielded RF coils, designed for demanding environments. The manufacturer specializes in custom and standard magnetic components for aerospace, defense, and medical sectors. The 15M121J represents a standard off-the-shelf option within their broader portfolio of axial and surface-mount inductors.

Replacement Considerations

Consult Gowanda Electronics for direct cross-reference models within the 15M series. Verify that any substitute maintains the 1.2 µH nominal value, 650 mA current rating, and axial package dimensions to ensure mechanical fit and electrical performance equivalence.
