Overview
The KEMET SSR21NHS-M10345 is a through-hole common mode filter choke designed for AC line filtering applications. It features a ferrite core and operates within a temperature range of -25°C to +120°C. The component provides an inductance of 34.5 mH at a test frequency of 10 kHz, with a maximum DC current rating of 1 A. Its maximum DC resistance is 510 mOhms, and it supports a voltage of 250VAC. The unshielded design measures 27 mm in height and 22 mm in diameter.
Feature Summary
- Provides common mode noise suppression for AC line circuits
- Utilizes a ferrite core for effective magnetic performance
- Designed for reliable operation across a wide industrial temperature range
Applications
- AC power line input filtering
- Electromagnetic interference (EMI) suppression in electronic equipment
- Common mode noise reduction in single-phase AC systems
Procurement Notes
Verify the specific suffix against official KEMET documentation to ensure correct pinout and mechanical dimensions. Confirm that the 1A current rating and 34.5mH inductance meet the target circuit requirements. Check for RoHS compliance status as indicated in the latest datasheet revision. Ensure the through-hole mounting style matches the PCB layout specifications.
Selection Notes
Select this component when a high-inductance common mode choke is required for low-current AC lines. The 1A rating suits applications where current demand remains below this threshold. Consider the physical dimensions for board space constraints. Compare against the SSR21NVS variant if different housing or terminal configurations are needed for the assembly process.
Part Context
This part belongs to the KEMET SSR21NVS-M/NHS-M series of AC line filters. These components are engineered for through-hole mounting on printed circuit boards. The series offers various inductance values tailored for different EMI suppression needs. The SSR21NHS-M10345 specifically targets applications requiring robust common mode attenuation at standard mains frequencies.
Replacement Considerations
The SSR21NVS-M10345 is a related variant within the same product family. Verify mechanical compatibility and electrical equivalence before substitution. Ensure the replacement maintains the required 34.5 mH inductance and 1A current handling capability for the specific application.
