SC22-05-70J

Overview

The KEMET SC22-05-70J is a two-line common mode choke designed for power line filtering applications. It features a nominal inductance of 7 mH measured at 10 kHz and supports a maximum rated current of 5 A. The component is rated for 250 V AC and 250 V DC, with a typical direct current resistance (DCR) of 60 mΩ. It utilizes a horizontal through-hole package with four pins and operates within a temperature range of -40°C to 120°C.

Feature Summary

• Provides effective common mode noise suppression for dual-line power circuits
• Engineered for high thermal stability across a wide operating temperature range
• Constructed for robust through-hole mounting in industrial environments

Applications

• Power supply input filtering
• Industrial equipment EMI suppression
• AC/DC converter noise reduction

Procurement Notes

Verify the specific suffix 'J' against the datasheet to confirm tolerance and material specifications. Confirm that the 60 mΩ DCR aligns with circuit loss requirements. Ensure the 5A current rating meets peak load demands without saturation. Check for end-of-life status or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a 7 mH inductance value is required for low-frequency common mode noise attenuation. The 5A current capacity suits moderate-power single-phase applications. Verify that the 250V voltage rating exceeds the system's peak line voltage. Consider the physical dimensions of the horizontal package for PCB layout constraints.

Part Context

This part belongs to the SC-JH series of common mode chokes from KEMET. The series is characterized by its use in general-purpose power line filtering where reliable noise suppression is critical. The SC22-05 base design indicates a specific form factor optimized for through-hole assembly in standard electronic enclosures.

Replacement Considerations

The manufacturer recommends SC-05-1100 as an alternative. Verify electrical compatibility including inductance, current rating, and voltage ratings before substitution.
