SSR21NVS-M30041

Overview

The KEMET SSR21NVS-M30041 is a through-hole common mode filter choke designed for AC line filtering applications. It features a ferrite core and operates within a temperature range of -25°C to +120°C. The component provides an inductance of 4.1 mH at a test frequency of 10 kHz, with a maximum DC resistance of 70 mOhms. It supports a rated current of 3 A and withstands up to 250 VAC. The unit measures 22.00 mm in length, 16.00 mm in width, and 27.00 mm in height.

Feature Summary

• Provides common mode noise suppression for AC power lines using a ferrite core structure.
• Designed for PCB mounting via through-hole termination with four pins.
• Operates reliably across a wide industrial temperature range from -25°C to +120°C.

Applications

• AC line input filtering for electronic equipment
• EMI suppression in power supply circuits
• Common mode noise reduction in single-phase AC systems

Procurement Notes

Verify the specific suffix M30041 against official KEMET documentation to confirm the exact inductance and current ratings. Ensure the procurement channel sources genuine components matching the manufacturer part number SSR21NVS-M30041. Cross-reference datasheet revisions to confirm compliance with current RoHS standards and material declarations before finalizing orders.

Selection Notes

Select this component when designing AC line filters requiring 4.1 mH inductance at 10 kHz with a 3 A current rating. The through-hole package suits boards where mechanical stability is prioritized over surface area constraints. Verify that the 250 VAC rating aligns with the target system voltage and that the operating temperature range covers the intended environmental conditions.

Part Context

This part belongs to the KEMET SSR series of common mode chokes, which are engineered for AC line filtering. The series utilizes ferrite cores to attenuate electromagnetic interference. The SSR21NVS-M30041 specifically denotes a variant with defined electrical characteristics for general-purpose AC line applications, distinct from higher or lower current variants within the same family.

Replacement Considerations

Direct substitutes must match the 4.1 mH inductance, 3 A current rating, and 250 VAC voltage rating. Verify pin compatibility and physical dimensions (22x16x27 mm) for board integration. Alternative parts from other manufacturers require equivalent thermal performance and common mode rejection characteristics.
