Overview
The KEMET SN12-400J is a through-hole common mode choke filter designed for electromagnetic interference suppression. It features an inductance of 64 µH and supports a maximum current rating of 5 A with a DC resistance of 37 mΩ. The component operates within a temperature range of -25°C to +105°C and utilizes a wire-wound construction suitable for axial lead mounting.
Feature Summary
- Provides common mode noise attenuation for signal and power lines
- Supports high current handling up to 5 Amperes
- Low DC resistance minimizes insertion loss in the circuit path
Applications
- Common mode filtering in data communication interfaces
- Noise suppression in industrial control systems
- EMI mitigation in automotive electronic modules
Procurement Notes
Verify the specific manufacturer datasheet for detailed mechanical dimensions and thermal derating curves. Confirm that the axial lead configuration matches the target PCB layout requirements. Ensure the operating environment remains within the specified -25°C to +105°C range to maintain performance integrity and reliability standards.
Selection Notes
Select this component when a robust, high-current common mode choke is required for axial mounting applications. The 64 µH value offers effective filtering for moderate frequency noise profiles. Consider the 37 mΩ resistance impact on voltage drop if used in low-voltage sensitive circuits compared to lower-inductance alternatives.
Part Context
This part belongs to KEMET's line of wire-wound common mode chokes. These components are engineered for durability in demanding environments. The SN12 series typically serves as a cost-effective solution for basic EMI suppression tasks where space constraints allow for axial leads rather than surface mount packages.
Replacement Considerations
Cross-reference with other KEMET axial common mode chokes offering similar 64 µH inductance and 5 A current ratings. Verify pin compatibility and physical footprint before substituting with generic equivalents from other manufacturers.
