Overview
The KEMET SSR21NV-M12345 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 34.5 mH at a test frequency of 10 kHz and supports a maximum DC current of 1.2 A. The component has a maximum DC resistance of 0.43 Ohms and is rated for 250 VAC. It operates within a temperature range of -25°C to +120°C. The physical dimensions are 16 mm in width, 27 mm in height, and 3.5 mm in length.
Feature Summary
- Provides common mode noise suppression for AC power lines
- Supports high current operation up to 1.2 A with low DC resistance
- Designed for reliable performance across a wide operating temperature range
Applications
- AC line input filtering in electronic equipment
- Noise reduction in power supply circuits
- EMI suppression for single-phase AC systems
Procurement Notes
Verify the specific suffix M12345 to ensure correct inductance and current ratings. Confirm RoHS compliance status as indicated in official documentation. Check for any recent Product Change Notifications (PCN) that may affect specifications or manufacturing location before finalizing procurement orders.
Selection Notes
Select this component when a 34.5 mH inductance is required for common mode noise attenuation at 1.2 A. Ensure the PCB layout accommodates the 27 mm height and through-hole mounting style. Compare against other series variants if different current or inductance values are needed for the specific application design.
Part Context
This part belongs to the KEMET SSR21NV-M series of common mode chokes. These components are engineered for AC line filtering and are characterized by their robust construction and consistent electrical performance. The series offers various inductance and current combinations to suit different power line requirements.
Replacement Considerations
SSR21NH-M12345 is a verified substitute with identical electrical characteristics including 34.5 mH inductance and 1.2 A rating. Verify pin compatibility and mechanical fit before substitution.
