15M272K

Overview

The 15M272K is a fixed axial leaded inductor manufactured by Gowanda Electronics. It features an unshielded molded construction with a nominal inductance of 27 µH and a tolerance of ±10%. The component has a maximum DC resistance of 2.6 Ohms and supports a DC current rating of 170 mA. It exhibits a minimum Q factor of 60 at a test frequency of 2.5 MHz, with a self-resonant frequency of 25 MHz.

Feature Summary

• Unshielded molded wirewound design for RF applications
• Axial leaded package configuration
• High Q factor performance at specified test frequencies

Applications

• Commercial off-the-shelf (COTS) electronic assemblies
• RF circuit filtering and tuning
• General purpose signal processing

Procurement Notes

Verify the specific suffix 'K' to confirm the ±10% tolerance variant. Ensure the unshielded axial form factor aligns with PCB layout requirements. Confirm RoHS compliance status as standard versions may not be compliant. Validate thermal ratings against operating environment constraints before finalizing procurement.

Selection Notes

Select this component when a 27 µH inductance value is required with moderate current handling capabilities. The unshielded design necessitates careful placement to avoid magnetic coupling with adjacent components. Consider the 170 mA DC current limit for power supply or biasing circuits where low impedance is not the primary requirement.

Part Context

This part belongs to Gowanda's line of molded unshielded RF coils. These components are designed for general-purpose radio frequency applications requiring stable inductance values. The axial lead style facilitates through-hole mounting on printed circuit boards.

Replacement Considerations

The 15M272KLF serves as a lead-free alternative within the same product family. Verify that the lead-free version maintains identical electrical parameters, including inductance, Q factor, and current ratings, to ensure functional compatibility in existing designs.
