SSR21NV-041290

Overview

The KEMET SSR21NV-041290 is a common mode choke filter designed for AC line applications. It features an inductance of 129 mH and supports a maximum DC current of 400 mA. The component has a maximum DC resistance of 1.85 Ohms and operates within a temperature range of -25°C to +120°C. Rated for 250VAC, it utilizes through-hole PCB mounting with dimensions of 3.5 mm length, 16 mm width, and 27 mm height.

Feature Summary

• Provides common mode noise suppression for AC power lines
• Supports through-hole printed circuit board mounting
• Operates at high temperatures up to 120°C

Applications

• AC line filtering in electronic equipment
• Common mode noise reduction in power supplies
• EMI suppression in single-channel AC circuits

Procurement Notes

Verify the End-of-Life status before procurement, as the manufacturer has issued discontinuation notifications. Confirm that alternative components meet the required 129 mH inductance and 400 mA current ratings. Ensure compatibility with existing PCB footprints and thermal management requirements for the specified operating temperature range.

Selection Notes

Select this component when specific common mode attenuation at 10 kHz is required for AC lines. The 1.85 Ohm DC resistance impacts power loss calculations; verify thermal performance under continuous load. The through-hole package requires adequate clearance on the PCB layout. Consider the physical dimensions if space constraints are critical in the final assembly design.
