Overview
The KEMET SSHB21H-R20094 is a dual-mode common mode choke designed for AC line filtering applications. It features an inductance of 9.4 mH measured at 10 kHz and supports a continuous current rating of 2 A. The component operates with a voltage rating of 250 VAC and exhibits a DC resistance of 170 mΩ. It functions reliably within a temperature range of -25°C to +120°C.
Feature Summary
- Dual-mode operation capability for enhanced noise suppression
- High inductance value suitable for effective common mode interference reduction
- Robust thermal performance across extended operating temperatures
Applications
- AC power line filtering in electronic equipment
- Noise suppression in mains-powered circuits
- EMI mitigation in industrial control systems
Procurement Notes
Verify the specific ordering suffix and package configuration against the official KEMET datasheet before procurement. Confirm that the 2A current rating and 250VAC voltage specifications align with the target circuit requirements. Ensure compliance with relevant safety standards for the intended application environment.
Selection Notes
Select this component when high inductance is required for common mode noise attenuation in AC lines. The 2A current capacity suits moderate power applications. Consider the 170mΩ DC resistance impact on voltage drop. Verify thermal management capabilities given the 120°C maximum operating limit.
Part Context
This component belongs to KEMET's common mode choke family, engineered for electromagnetic interference suppression. It utilizes magnetic core technology to block high-frequency noise while allowing differential signals to pass. The design prioritizes compact form factors for integration into space-constrained power supply modules.
Replacement Considerations
Consult KEMET documentation for direct cross-references. Verify equivalent inductance, current rating, and physical dimensions before substitution. Ensure replacement parts meet identical safety certifications and thermal ratings.
