15M331K

Overview

The 15M331K is a fixed axial leaded inductor from Gowanda Electronics, designed for general-purpose RF applications. It features an unshielded molded construction with an iron-ferrite core and phenolic bobbin. The component provides a nominal inductance of 3.3 µH with a tolerance of ±10%. It has a maximum DC resistance of 2 Ohms and a rated current of 300 mA. The device operates within a temperature range of -55 °C to +105 °C.

Feature Summary

• Unshielded molded design suitable for non-critical magnetic environments
• Iron-ferrite core material optimized for RF frequency performance
• Axial through-hole configuration for standard PCB mounting

Applications

• General purpose RF filtering circuits
• Signal processing inductive components
• Broadband power supply chokes

Procurement Notes

Verify RoHS compliance status as the base model may contain lead; confirm suffix LF if lead-free requirement exists. Ensure axial lead spacing matches target PCB footprint. Validate operating temperature limits against system thermal profile. Confirm unshielded nature does not interfere with adjacent sensitive circuitry.

Selection Notes

Select this component when unshielded axial inductors are required for RF applications. Compare DC resistance and current ratings against circuit load requirements. Consider physical size constraints for axial leads. Verify core material suitability for specific frequency ranges.

Part Context

This part belongs to the 15M series of molded unshielded RF coils manufactured by Gowanda Electronics. The series offers various inductance values in axial packages, catering to industrial and commercial electronic designs requiring reliable passive components.

Replacement Considerations

Cross-reference with other 3.3 µH axial unshielded inductors. Verify identical core material (iron-ferrite) and tolerance (±10%). Check equivalent DC resistance and current handling capabilities before substitution.
