SH-122

Overview

The KEMET SH-122 is a through-hole common mode choke utilizing a Nickel-Zinc ferrite core. It provides an inductance of 1.5 µH at 100 kHz with a rated current of 3 A and a DC resistance of 20 mΩ. The component operates within a temperature range of -25°C to +80°C and features a UL94 V-0 flame retardant terminal base.

Feature Summary

• Utilizes Nickel-Zinc ferrite core for effective common mode noise suppression
• Features a UL94 V-0 flame retardant terminal base for safety compliance

Applications

• Signal line filtering in electronic circuits
• Common mode noise reduction in data transmission interfaces
• Power supply input filtering for low voltage applications

Procurement Notes

Verify the specific suffix or variant against the official KEMET datasheet to ensure compatibility with required current ratings and impedance characteristics. Confirm that the operating temperature range of -25°C to +80°C meets the environmental requirements of the target application before procurement.

Selection Notes

Select this component when a through-hole solution is required for common mode interference suppression on signal lines. The 3 A current rating and low DC resistance make it suitable for applications where minimal signal attenuation is critical while maintaining effective noise filtration capabilities.

Part Context

The SH series represents KEMET's line of through-hole common mode chokes designed for general-purpose filtering. These components are engineered to provide reliable performance in compact spaces, offering a balance between inductance value and current handling capacity for various industrial and consumer electronics applications.

Replacement Considerations

Consult KEMET documentation for direct cross-references. Ensure any substitute maintains the 1.5 µH inductance, 3 A current rating, and through-hole mounting style to preserve circuit integrity.
