Overview
The 15M122J is a fixed axial lead inductor manufactured by Gowanda Electronics. It features a molded unshielded construction with a powdered iron core, designed for radio frequency applications. The component has an inductance of 12 µH and a maximum DC resistance of 1.1 Ohms. Its rated maximum current is 265 mA. The device utilizes lead-based termination (Sn63Pb37) and carries a moisture sensitivity level of 1.
Feature Summary
- Unshielded molded design suitable for general RF coil applications
- Powdered iron core material for stable magnetic performance
- Axial lead configuration for through-hole mounting
Applications
- Radio frequency signal processing circuits
- General purpose inductive filtering
- Broadband power transformer biasing networks
Procurement Notes
Verify the specific ordering suffix to confirm termination composition. Standard variants may differ in lead plating or RoHS compliance status. Confirm that the unshielded construction aligns with electromagnetic interference requirements for the target assembly. Ensure axial lead dimensions match the printed circuit board layout constraints.
Selection Notes
Select this component when a 12 µH inductance value is required with a 265 mA current rating. The unshielded design necessitates careful placement to avoid coupling with adjacent sensitive traces. Consider the 1.1 Ohm DC resistance impact on series voltage drops. The axial form factor dictates vertical or horizontal board orientation during installation.
Part Context
This part belongs to Gowanda's line of molded RF coils. These components are engineered for aerospace, defense, and medical sectors requiring high reliability. The manufacturer maintains ISO 9001 and AS9100 certifications. Products are often tailored for harsh environments where standard commercial inductors may fail due to thermal or mechanical stress.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 12 µH inductance, 265 mA current rating, and axial package style. Verify core material compatibility if replacing with non-Gowanda brands.
