15M121KLF

Overview

The 15M121KLF is a molded unshielded RF coil manufactured by Gowanda Electronics. It features an axial lead configuration and a phenolic core construction. The component provides an inductance of 1.2 µH with a maximum DC resistance of 420 mΩ and a rated current of 650 mA. Designed for surface mount or through-hole integration, it operates within a temperature range suitable for general electronic applications.

Feature Summary

• Molded unshielded RF coil design
• Axial lead configuration
• Phenolic core construction

Applications

• RF circuit filtering
• General purpose inductive applications
• Electronic signal processing

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status, as Gowanda offers both compliant and non-compliant variants within similar series. Ensure the axial package dimensions match the target PCB footprint. Confirm that the 650 mA rated current meets the thermal requirements of the intended application environment.

Selection Notes

Select this component when an unshielded axial inductor is required for RF applications. The 1.2 µH value suits specific frequency filtering needs. Consider the 420 mΩ DC resistance for power loss calculations. Verify that the lack of shielding does not interfere with nearby sensitive components due to potential magnetic field emission.

Part Context

This part belongs to Gowanda's line of fixed inductors, specifically the 15M series which focuses on molded unshielded RF coils. These components are designed for reliability in demanding environments. The manufacturer specializes in high-performance electronic components for aerospace, defense, and industrial sectors.

Replacement Considerations

Direct substitutes include other 1.2 µH axial RF coils from Gowanda, such as the 15M121J variant if tolerance differences are acceptable. Cross-brand replacements require matching the 1.2 µH inductance, 650 mA current rating, and axial package dimensions.
