Overview
The KEMET SSHB21H-07340 is a through-hole dual mode common mode choke designed for AC line filtering. It features an inductance of 34 mH at 10 kHz and supports a maximum DC current of 700 mA with a maximum DC resistance of 1.16 Ohms. Rated for 250 VAC, the component operates within a temperature range of -40°C to 130°C. This two-line filter provides effective noise suppression for power supply inputs.
Feature Summary
- Dual mode operation for enhanced common mode noise attenuation
- Through-hole mounting for secure PCB integration
- High inductance value for effective low-frequency interference suppression
Applications
- Power supply input filtering
- AC line noise suppression
- Electromagnetic interference (EMI) reduction in consumer electronics
Procurement Notes
Verify the specific suffix against official KEMET documentation to ensure correct inductance and current ratings. Confirm package type and terminal configuration match design requirements. Check operating temperature limits for environmental compatibility. Ensure compliance with relevant safety standards for the intended application region.
Selection Notes
Select this component when high inductance is required for low-frequency common mode noise. The through-hole format suits applications requiring mechanical robustness. Verify that the 700 mA current rating meets the circuit's peak load demands. Consider the physical size constraints for PCB layout integration.
Part Context
This part belongs to the SSHB21H series of dual mode chokes from KEMET. These components are engineered for general-purpose EMI filtering in AC power lines. The series offers various inductance values to suit different noise profiles while maintaining consistent physical dimensions for standardized mounting.
Replacement Considerations
Check for direct substitutes within the SSHB21H series with matching 34 mH inductance. Verify equivalent current ratings and voltage specifications. Ensure compatible mounting style and terminal pitch for board replacement.
