Overview
The KEMET SSR21NHS-10160 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 16 mH at a test frequency of 10 kHz and supports a maximum DC current of 1 A. The component exhibits a maximum DC resistance of 290 mOhms and operates within a temperature range of -25 C to +120 C. Its physical dimensions are 23 mm in diameter with a height of 14.5 mm, utilizing proprietary S15H ferrite material for high permeability.
Feature Summary
- Utilizes proprietary S15H ferrite material for high permeability characteristics
- Provides high impedance across a wide frequency range due to divided bobbin design
- Offers compact size, low profile, and lightweight construction
Applications
- AC line filtering
- Common mode noise suppression
- Electronic equipment power input stages
Procurement Notes
Verify the specific suffix 'H' against the original design specification, as it denotes the core material variant. Confirm that the 1 A current rating aligns with the thermal requirements of the final assembly. Ensure PCB layout accommodates the 23 mm diameter footprint and 14.5 mm height clearance. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.
Selection Notes
Select this component when high impedance over a broad frequency spectrum is required for common mode noise reduction. The S15H ferrite material offers superior performance compared to standard cores. Consider the 1 A current limit and 290 mOhm resistance for efficiency calculations. The through-hole mounting style provides robust mechanical stability for AC line connections.
Part Context
This part belongs to the SSR21NHS series of common mode chokes manufactured by KEMET. The series is characterized by the use of specialized ferrite materials to enhance filtering capabilities in compact form factors. These components are typically used in power supply inputs to mitigate electromagnetic interference generated by switching circuits or external sources.
Replacement Considerations
SSR21NVS-10160 shares identical electrical parameters including 16 mH inductance, 1 A current rating, and 290 mOhm DCR. Verify if the 'V' versus 'H' suffix indicates a different ferrite composition or coating that affects performance in the specific application environment.
