Overview
The KEMET SSR21NH-M08680 is a through-hole common mode choke designed for AC line filtering applications. It operates at a rated voltage of 250VAC and provides an inductance of 68mH, measured at a test frequency of 10 kHz. The component supports a maximum DC current of 0.8A with a maximum DC resistance of 800 mOhms. It functions within a temperature range of -40°C to +120°C. The physical dimensions are 3.5 mm in length, 22 mm in width, and 27 mm in height, weighing approximately 14.5 g.
Feature Summary
- Provides common mode noise suppression for AC power lines
- Utilizes a through-hole bobbin construction for PCB mounting
- Engineered for high-temperature stability up to 120°C
Applications
- AC power line EMI filtering
- Switch-mode power supply input stages
- General electronic equipment noise reduction
Procurement Notes
Verify the specific suffix against official KEMET documentation to confirm electrical tolerances and material compliance. Ensure the ordering part number matches the required inductance and current ratings precisely. Cross-reference the manufacturer's latest datasheet for any updates on RoHS status or packaging configurations before finalizing procurement orders.
Selection Notes
Select this component when a 68mH inductance value is required for common mode noise attenuation in AC circuits. The 0.8A current rating must align with the circuit's operational load. Verify that the through-hole footprint and 27mm height fit within the available PCB real estate and enclosure constraints.
Part Context
This component belongs to the KEMET SSR21 series of common mode chokes. These parts are engineered for robust performance in AC line filter applications. The series offers various inductance and current combinations to suit different power requirements while maintaining consistent physical mounting characteristics for design flexibility.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's cross-reference tools or technical support for verified alternatives that match the 68mH inductance and 0.8A current specifications.
