Overview
The 10M391KLF is a molded unshielded RF coil manufactured by Gowanda Electronics. It features an inductance of 3.9 µH with a tolerance of ±10%. The component has a maximum DC resistance of 1 Ohm and a rated current of 250 mA. It utilizes a wirewound construction suitable for axial through-hole mounting. The minimum quality factor is specified as 45 at a test frequency of 7.9 MHz.
Feature Summary
- Molded unshielded wirewound construction
- Axial lead configuration for through-hole mounting
- Designed for commercial off-the-shelf applications
Applications
- Commercial off-the-shelf (COTS) electronic systems
- RF circuit filtering
- General purpose inductive components
Procurement Notes
Verify the specific RoHS compliance status and lead content, as Gowanda offers both compliant and traditional leaded variants within this series. Confirm that the axial package dimensions match the target PCB layout requirements. Ensure the 250 mA current rating meets the operational demands of the intended circuit design before finalizing procurement.
Selection Notes
Select this component when an unshielded axial inductor is required for COTS applications. The 3.9 µH value and 250 mA rating define its electrical limits. Consider the physical size constraints associated with the axial lead format. Verify that the lack of shielding does not interfere with nearby sensitive circuitry due to potential magnetic field emission.
Part Context
This part belongs to the 10M series of molded unshielded RF coils from Gowanda Electronics. The series provides various inductance values using wirewound technology. These components are engineered for reliability in aerospace, defense, and medical sectors, offering standardized options alongside custom design capabilities for demanding environments.
Replacement Considerations
Substitutes must match the 3.9 µH inductance, axial package, and similar current handling. Check datasheets for equivalent Q factors and DC resistance values to ensure circuit performance remains unchanged during replacement.
