SSR21HS-07245

Overview

The KEMET SSR21HS-07245 is a through-hole common mode choke designed for AC line filtering. It features an inductance of 24.5 mH at 10 kHz and supports a maximum DC current of 700 mA. The component has a DC resistance of 590 mOhms and is rated for 250 VAC. It utilizes a ferrite core and is unshielded, with dimensions of 3.5 mm length, 27 mm height, and 22 mm diameter.

Feature Summary

• Provides common mode noise suppression for AC power lines
• Utilizes a ferrite core for effective EMI filtering
• Designed for through-hole PCB mounting

Applications

• AC-DC power supply input filtering
• Consumer electronics EMI suppression
• Industrial control system power lines

Procurement Notes

Verify the specific voltage and current ratings against your circuit requirements before integration. Confirm that the through-hole footprint matches your PCB layout. Check for RoHS compliance status if required by your manufacturing standards. Ensure the operating temperature range meets your environmental conditions.

Selection Notes

Select this component when high inductance is needed for low-frequency common mode noise reduction. The 700 mA rating suits moderate current applications. Consider the physical size constraints as the unit is relatively large compared to surface mount alternatives. Verify compatibility with your assembly process for through-hole components.

Part Context

This part belongs to the SSR21HS series of common mode chokes from KEMET. These components are engineered for general-purpose AC line filtering. The series offers various inductance values to suit different noise profiles. They are commonly used in equipment requiring robust EMI performance on mains inputs.

Replacement Considerations

SSR21NVS-M10345 is a related common mode choke from KEMET but differs in inductance (34.5 mH) and current rating (1 A). Verify electrical parameters match your design needs before substitution.
