SC-20-10JH

Overview

The KEMET SC-20-10JH is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 1 mH at 100 kHz and supports a DC current rating of 20 A. The component has a maximum DC resistance (DCR) of 8 mΩ and operates within a temperature range from -40°C to +105°C. Rated for 250 VAC, it utilizes a two-line configuration to suppress electromagnetic interference on power lines.

Feature Summary

• Provides effective common mode noise suppression for AC power lines
• Supports high continuous current handling up to 20 A
• Low DC resistance minimizes power loss and heat generation
• Through-hole construction ensures robust mechanical mounting

Applications

• AC power input filtering for industrial equipment
• Electromagnetic interference suppression in consumer electronics
• Power supply input stages requiring common mode noise reduction

Procurement Notes

Verify the specific suffix and voltage rating against the official KEMET datasheet to ensure compatibility with the target circuit requirements. Confirm that the through-hole package dimensions match the PCB layout constraints. Check for RoHS compliance status if required by regional regulations or end-product specifications before finalizing procurement decisions.

Selection Notes

Select this component when high current capacity and low impedance are critical for power line filtering. Ensure the operating temperature range meets the environmental conditions of the application. Consider the physical size and lead spacing for adequate clearance and creepage distances in high-voltage designs.

Part Context

This component belongs to the SC-20 series of common mode chokes manufactured by KEMET. The series is engineered for general-purpose AC line filtering, offering a balance of electrical performance and mechanical reliability. It is commonly used in applications where standard EMI suppression is required without specialized high-frequency characteristics.

Replacement Considerations

Consult official KEMET documentation for verified substitute part numbers within the SC-20 series or equivalent product lines. Ensure any replacement matches the 1 mH inductance, 20 A current rating, and 8 mΩ DCR specifications. Verify package compatibility and voltage ratings before substitution.
