Overview
The KEMET SSR21NVS-M25064 is a through-hole common mode choke designed for EMI/RFI suppression in AC power lines. It features an inductance of 6.4 mH and supports a continuous current rating of 2.5 A at 250 VAC. The component exhibits a low DC resistance (DCR) of 0.09 mOhms, ensuring minimal voltage drop and power loss during operation. With a physical height of 20.9 mm, it is suitable for standard PCB mounting configurations requiring robust noise filtering capabilities.
Feature Summary
- Provides effective attenuation of electromagnetic interference in single-phase AC circuits
- Utilizes through-hole technology for secure mechanical attachment to printed circuit boards
- Engineered with low DC resistance to maintain signal integrity and reduce thermal generation
Applications
- Input filtering for switch-mode power supplies
- Noise suppression in consumer electronic devices
- EMI mitigation in industrial control systems
Procurement Notes
Verify the specific suffix M25064 against the manufacturer's latest datasheet to confirm electrical tolerances and pinout compatibility. Ensure that the selected component meets all relevant safety certifications required for the target market, such as UL or CQC, before finalizing procurement decisions for production integration.
Selection Notes
Select this component when a 6.4 mH inductance value is required for common mode noise reduction in 250 VAC applications. The 2.5 A current rating must align with the maximum load current of the circuit. Consider the 20.9 mm height constraint during PCB layout planning to ensure adequate clearance from adjacent components and enclosure structures.
Part Context
This part belongs to the KEMET SSR21NVS-M series of common mode chokes. These components are specifically engineered for general-purpose EMI suppression in AC line applications. The series offers various inductance and current ratings to accommodate different power levels and noise profiles found in modern electronic equipment designs.
Replacement Considerations
Direct substitutes include other KEMET parts within the same series with matching inductance and current ratings, such as variants with different DCR values if thermal performance differs. Cross-brand replacements require careful verification of inductance tolerance, saturation current, and physical footprint dimensions to ensure functional equivalence.
