SS21V-250015

Overview

The KEMET SS21V-250015 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 1.5 mH and supports a maximum DC current of 2.5 A with a low DC resistance of 100 mOhms. Rated for 250 VAC, this component operates within a temperature range of -25°C to +120°C. The vertical PCB mount design measures 24.5 mm in height, 20.6 mm in length, and 16.5 mm in width, utilizing proprietary ferrite materials suitable for frequencies ≥ 150 kHz.

Feature Summary

• Utilizes proprietary 5H and 10H ferrite materials for effective noise suppression
• Vertical radial leaded construction for standard PCB mounting
• Optimized performance for electromagnetic interference filtering in the ≥ 150 kHz range

Applications

• AC power line input filtering
• Electromagnetic interference (EMI) suppression in electronic equipment
• Common mode noise reduction in power supplies

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with KEMET or authorized distributors before procurement. Confirm that the vertical lead configuration and physical dimensions align with your PCB footprint requirements. Ensure the operating environment remains within the specified -25°C to +120°C thermal limits to maintain component integrity and electrical performance standards.

Selection Notes

Select this component when high current handling capability of 2.5 A is required alongside significant common mode attenuation. The vertical form factor aids in space-constrained board layouts where height clearance is available. Consider the 100 mOhm DCR for efficiency calculations in low-voltage drop applications requiring robust EMI protection at higher frequencies.

Part Context

Part of the KEMET SS21V series, which offers a variety of sizes and specifications for common mode chokes. This series leverages specialized ferrite materials to address diverse EMI filtering needs across different power levels and frequency ranges, providing reliable performance for industrial and commercial electronic designs.

Replacement Considerations

Check for direct substitutes within the SS21V series with adjusted inductance or current ratings. Verify compatibility with alternative manufacturers offering similar vertical through-hole common mode chokes rated for 250 VAC and 2.5 A, ensuring equivalent ferrite material properties and dimensional fit.
