Overview
The KEMET SSR21NHS-M15164 is a through-hole common mode filter choke designed for AC line filtering applications. It features an inductance of 16.4 mH and supports a maximum DC current of 1.5 A. The component has a maximum DC resistance of 0.23 Ohms and operates within a temperature range of -25°C to +120°C. Rated for 250VAC, it utilizes ferrite core technology and measures 23 mm in diameter with a height of 27 mm.
Feature Summary
- Provides common mode noise suppression for AC power lines
- Utilizes ferrite core material for effective electromagnetic interference filtering
- Designed for reliable operation across a wide industrial temperature range
Applications
- AC line input filtering in electronic equipment
- Electromagnetic interference suppression in power supplies
- Common mode noise reduction in consumer electronics
Procurement Notes
Verify the specific part number suffix against official KEMET documentation to ensure correct electrical ratings and physical dimensions. Confirm RoHS compliance status directly from the manufacturer datasheet before integration. Cross-reference the alias UALS21H1516400 if sourcing from distributors using alternative naming conventions. Ensure PCB footprint compatibility with the specified through-hole mounting style.
Selection Notes
Select this component when a 16.4 mH inductance value is required for common mode noise attenuation at 1.5 A current levels. The 230 mOhm DC resistance offers low insertion loss compared to higher impedance alternatives. Consider the 27 mm height for vertical clearance constraints on the printed circuit board assembly.
Part Context
This component belongs to the KEMET SSR21NHS-M series of common mode chokes. These devices are engineered for general-purpose AC line filtering tasks. The series provides standardized form factors for easy integration into various power supply designs and electronic enclosures requiring EMI mitigation.
Replacement Considerations
The part is also identified by the alias UALS21H1516400. Verify equivalent specifications such as inductance, current rating, and physical dimensions when considering substitute components from other manufacturers.
