10M242J

Overview

The 10M242J is a general-purpose, unshielded wirewound inductor manufactured by Gowanda Electronics. It features an axial leaded package with a rectangular form factor and a powdered iron core. The component provides a nominal inductance of 24 µH with a tolerance of ±5%. It exhibits a maximum DC resistance of 3.4 Ohms and a rated current of 137 mA. Designed for through-hole mounting, it operates within a temperature range of -55 °C to +105 °C. The unit measures 6.35 mm in length with a diameter of 2.413 mm and utilizes leads with a diameter of 0.5105 mm.

Feature Summary

• Unshielded wirewound construction utilizing a powdered iron core for stable magnetic performance
• Axial leaded configuration designed for standard through-hole PCB mounting applications
• RoHS compliant manufacturing ensuring adherence to environmental standards

Applications

• RF coil circuits requiring general-purpose inductance
• Signal filtering in electronic assemblies
• Power supply circuitry components

Procurement Notes

Verify the specific suffix requirements when ordering, as variations such as LF denote RoHS compliance status. Confirm that the axial lead dimensions align with your board layout constraints. Ensure the operating temperature range meets the thermal requirements of the target environment. Cross-reference the DC resistance and current ratings against the circuit design specifications to prevent saturation or excessive voltage drop during operation.

Selection Notes

Select this component for applications requiring a fixed 24 µH inductance with moderate current handling capabilities. The unshielded design may require careful placement to minimize electromagnetic interference with nearby sensitive traces. Consider the axial form factor for ease of manual assembly or automated through-hole processes. Evaluate the 3.4 Ohm DC resistance impact on overall circuit efficiency before finalizing the design choice.

Part Context

This part belongs to the 10M series of standard RF inductors produced by Gowanda Electronics. The series offers a wide range of inductance values tailored for radio frequency and general electronic applications. Components in this line are characterized by their molded construction and consistent electrical parameters, providing reliability for industrial and commercial electronics manufacturing needs.

Replacement Considerations

The 10M242JLF serves as a direct equivalent variant, differing primarily in its explicit RoHS compliance designation. When substituting, ensure the physical footprint and lead spacing remain compatible with the existing PCB design. Verify that any alternative component matches the 24 µH nominal value and 137 mA current rating to maintain circuit integrity.
