ELF-15N022A

Common Mode Chokes Overview

The Panasonic ELF-15N022A is a common mode choke belonging to the N Series Type 15N line filter family. It features a radial through-hole mounting style with a single channel configuration. Key electrical parameters include an inductance of 1 mH with a 20% tolerance, a maximum DC current rating of 2.2 A, and a typical maximum DC resistance of 78 mOhms. The component operates within a temperature range of -20°C to +115°C. Physical dimensions are 22.7 mm in length, 15 mm in width, and 21.5 mm in height.

Common Mode Chokes Feature Summary

• Increases common-mode impedance at the interface to reduce high-frequency common-mode surge energy coupling into the PCB.

Common Mode Chokes Applications

• AC line filtering for electronic equipment
• Common mode noise suppression in power interfaces

Common Mode Chokes Procurement Notes

Verify end-of-life status as official documentation indicates discontinuation of the ELF-xxN series production. Confirm availability through authorized channels or secondary markets, noting that standard distribution may be limited. Ensure compliance with RoHS requirements by checking specific revision details on the datasheet before procurement.

Common Mode Chokes Selection Notes

Select this component when a 1 mH inductance and 2.2 A current handling capability are required for common mode noise reduction. Verify that the radial leaded package fits the PCB layout constraints. Consider the operating temperature range of -20°C to +115°C against environmental conditions. Check for alternative parts if new design-in is preferred due to discontinuation status.

Common Mode Chokes Part Context

This part belongs to the Panasonic ELF-xxN series AC line filters. Production was transferred from Singapore/Batam Island, Indonesia to Jiangmen, China. The series has subsequently faced discontinuation notices, marking it as a legacy component in the manufacturer's portfolio for common mode chokes.

Common Mode Chokes Replacement Considerations

Official discontinuation notices confirm the end of production for the ELF-xxN series. No direct public substitute part numbers are listed in the provided documentation. Designers should evaluate equivalent common mode chokes with matching 1 mH inductance and 2.2 A ratings from other manufacturers.
