SSR21NH-M25103

Overview

The KEMET SSR21NH-M25103 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 10.3 mH and supports a maximum DC current of 2.5 A. The component has a maximum DC resistance of 0.12 Ohms and operates within a temperature range of -25°C to +120°C. Rated for 250VAC, it utilizes a ferrite core and measures 16 mm in width, 27 mm in height, and 3.5 mm in length.

Feature Summary

• Provides common mode noise suppression for AC power lines
• Utilizes a bobbin-wound design with a ferrite core
• Supports high current operation up to 2.5 A

Applications

• AC input filtering in power supplies
• EMI suppression in consumer electronics
• Line filtering in industrial control equipment

Procurement Notes

Verify the specific suffix (NH vs NV) against the datasheet to confirm exact physical dimensions and material specifications. Confirm RoHS compliance status directly from the manufacturer's documentation. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement.

Selection Notes

Select this component when a 10.3 mH inductance is required for common mode noise reduction at currents up to 2.5 A. The low DC resistance minimizes power loss in the circuit. Verify that the through-hole footprint and board space accommodate the 16x27 mm package dimensions.

Part Context

This part belongs to the KEMET SSR21NV/M series of through-hole bobbin common mode chokes. These components are engineered for AC line filtering and EMI suppression. The series offers various inductance and current ratings to suit different power supply requirements while maintaining a consistent mounting style.

Replacement Considerations

Cross-reference with SSR21NV-M25103 for potential dimensional or material variations. Verify equivalent inductance and current ratings if substituting with other manufacturers' common mode chokes.
