SSHB21HS-R20071

Overview

The KEMET SSHB21HS-R20071 is a dual-mode common mode filter choke designed for AC line applications. It features an inductance of 7.1 mH at a test frequency of 10 kHz and supports a maximum DC current of 2 A. The component has a maximum DC resistance of 140 mOhms and operates within a temperature range of -25°C to +120°C. Rated for 250 VAC, it utilizes through-hole mounting with a 21 mm lead spacing. Physical dimensions include a height of 15.5 mm, width of 23 mm, and length of 26 mm.

Feature Summary

• Dual-mode filtering capability for enhanced noise suppression
• Through-hole construction for PCB integration
• High current handling capacity up to 2 A

Applications

• AC line input filtering
• Electronic device noise suppression
• Power supply EMI reduction

Procurement Notes

Verify the specific part number suffix against official KEMET documentation to ensure correct electrical ratings. Confirm that the 7.1 mH inductance and 2 A current rating match the design requirements. Check for RoHS compliance status in the latest datasheet before procurement.

Selection Notes

Select this component when dual-mode filtering is required for AC lines. Ensure the operating environment stays within the -25°C to +120°C range. Verify that the 21 mm lead spacing fits the PCB layout constraints. Compare the 140 mOhms DCR against system power loss limits.

Part Context

This component belongs to the SSHB21HS series of common mode chokes from KEMET. The series is characterized by its dual-mode filtering technology and robust through-hole packaging. These filters are engineered for reliable performance in AC line applications where significant noise attenuation is necessary.

Replacement Considerations

SSHB21HS-12110 is a related model in the same series but differs in inductance (11 mH) and current rating (1.2 A). Verify compatibility before substitution as electrical parameters vary significantly between these part numbers.
