SSR21NV-M18164

Overview

The KEMET SSR21NV-M18164 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 16.4 mH and supports a maximum DC current of 1.8 A. The component operates within a temperature range of -25°C to +120°C and has a maximum DC resistance of 210 mOhms. Rated for 250 VAC, it utilizes a bobbin construction with dimensions of 3.5 mm length, 16 mm width, and 27 mm height.

Feature Summary

• Provides common mode noise suppression for AC power lines
• Supports high operating temperatures up to 120°C
• Designed for reliable through-hole PCB mounting

Applications

• AC line input filtering
• Power supply EMI reduction
• Electronic equipment noise suppression

Procurement Notes

Verify the specific suffix M against NH variants to ensure correct physical footprint compatibility. Confirm that the 1.8 A current rating meets circuit requirements. Check RoHS compliance status as indicated in official documentation. Ensure the through-hole package aligns with PCB layout specifications before ordering.

Selection Notes

Select this component when 16.4 mH inductance at 1.8 A is required for common mode noise attenuation. The 210 mOhm DCR minimizes voltage drop compared to higher impedance alternatives. The wide temperature range suits industrial environments. Verify spatial constraints fit the 16x27 mm profile.

Part Context
