Overview
The KEMET SN3-100 is a common mode choke coil designed for normal mode noise countermeasures. It features a proprietary iron dust core and offers a rated current AC range starting from 500mA. The component has an inductance of 2.5 µH, a maximum DC resistance of 0.025 ohms, and supports a rated current of 3.0A. It utilizes through-hole mounting with two pins and operates within a temperature range of -25°C to 105°C.
Feature Summary
- Proprietary iron dust core construction for effective normal mode noise suppression
- Through-hole mounting configuration suitable for vertical installation
- Designed for power line filtering applications
Applications
- Power supply input filtering
- Normal mode noise reduction in electronic circuits
- AC line interference suppression
Procurement Notes
Verify the specific datasheet for the SN3-100 model to confirm exact electrical parameters such as inductance tolerance and saturation current limits. Ensure the selected variant matches the required current rating and physical dimensions for the target PCB layout. Cross-reference official manufacturer documentation to validate compliance with relevant safety and environmental standards before finalizing procurement decisions.
Selection Notes
Select this component when normal mode noise mitigation is required in low-to-medium current applications up to 3.0A. The iron dust core provides stable performance under varying load conditions. Consider the through-hole form factor for robust mechanical connection. Evaluate thermal management requirements based on the specified operating temperature range and DC resistance characteristics.
Part Context
The SN3-100 belongs to the KEMET SN series of common mode chokes. This series is characterized by the use of proprietary iron dust cores, which distinguish it from other ferrite-based solutions. The SN series covers a broad range of rated currents, providing flexibility for various power line filtering needs across different industrial and consumer electronics applications.
Replacement Considerations
Direct substitutes may include other KEMET SN series components with similar inductance and current ratings. Verify compatibility with existing board space and pin configurations. Consult manufacturer cross-reference guides for equivalent parts offering identical electrical specifications and mechanical footprint.
