Common Mode Chokes Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status upon order confirmation, as this part may be subject to availability changes. Confirm that the through-hole package dimensions match the target PCB footprint requirements. Ensure that the 300 mA current rating and 2.3 Ohm DC resistance specifications align with the design constraints of the final application to prevent performance degradation or thermal issues during operation.

Common Mode Chokes Selection Notes

Select this component when a through-hole solution is required for common mode noise attenuation in low-current applications. The 300 mA rating suits compact power stages where space allows for axial or radial leaded components. Consider the 2.3 Ohm DC resistance impact on voltage drop if used in series with sensitive signal lines. Verify that the operating temperature range meets the environmental conditions of the end-use device.

Common Mode Chokes Part Context

This component belongs to the ELF-14 series of common mode chokes manufactured by Panasonic Industry. The series offers various inductance and current ratings tailored for different filtering needs. As a through-hole device, it provides mechanical stability compared to surface-mount alternatives, making it suitable for applications requiring robust physical connections and high reliability in consumer electronics and industrial control systems.

Common Mode Chokes Replacement Considerations

Check Panasonic's official documentation for direct cross-references within the ELF-14 series. Verify that any substitute maintains the same 300 mA current handling and 2.3 Ohm DC resistance characteristics. Ensure the replacement component supports through-hole mounting and matches the physical lead spacing of the original design.
