SC-05-E45JH

Common Mode Chokes Overview

The KEMET SC-05-E45JH is a through-hole common mode choke from the SC-JH series, designed for AC line filtering. It features an inductance of 4.5 mH at 100 kHz and supports a maximum DC current of 5 A. The component has a maximum DC resistance of 50 mΩ and operates within a temperature range of -40°C to 120°C. Rated for 250 V AC/DC, it utilizes a ferrite core and is RoHS compliant.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression for AC power lines
• Utilizes a ferrite core for high-frequency interference attenuation
• Supports high current handling with low DC resistance
• Designed for robust through-hole PCB mounting

Common Mode Chokes Applications

• AC power input filtering for electronic equipment
• Noise suppression in industrial control systems
• EMI reduction in consumer appliance power supplies

Common Mode Chokes Procurement Notes

Verify the specific operating temperature range requirements against the datasheet, as sources indicate variations between -40°C and -25°C minimums. Confirm the exact DC resistance value (50 mΩ) matches design constraints. Ensure the through-hole footprint dimensions align with the target PCB layout before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a 4.5 mH inductance is required for common mode noise rejection in AC applications. It is suitable for circuits demanding up to 5 A continuous current. Consider the SC-JH series for its specific thermal performance up to 120°C and its compatibility with standard through-hole assembly processes for reliable mechanical attachment.

Common Mode Chokes Part Context

This part belongs to the KEMET SC-JH series of common mode chokes. These components are engineered for power line filtering applications where significant inductance and current capacity are necessary. The series offers various inductance values to suit different EMI suppression needs while maintaining a consistent form factor for easy integration into existing designs.

Common Mode Chokes Replacement Considerations

The SC-05-100JV is a similar KEMET common mode choke but differs significantly in inductance (15 mH vs 4.5 mH) and DC resistance (100 mΩ vs 50 mΩ). Verify that the higher inductance and resistance do not adversely affect the circuit's performance or efficiency before substituting.
