SN3-200

Overview

The KEMET SN3-200 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 10 µH and supports a maximum DC current of 1 A with a maximum DC resistance of 45 mΩ. The component operates within a temperature range of -25 °C to +105 °C and utilizes an iron core construction.

Feature Summary

• Provides common mode noise suppression for AC line circuits
• Utilizes iron core construction for stable inductance performance
• Designed for through-hole PCB mounting

Applications

• AC line input filtering
• EMI suppression in power supplies
• General electronic equipment noise reduction

Procurement Notes

Verify the specific datasheet version for the SN3-200, as some sources indicate 48 µH while others specify 10 µH. Confirm the maximum DC current rating (1 A) and DC resistance (45 mΩ or 58 mΩ) against the manufacturer's official documentation before procurement to ensure compatibility with circuit requirements.

Selection Notes

Select this component for applications requiring through-hole common mode chokes with low DC resistance. Ensure the operating temperature range of -25 °C to +105 °C meets environmental conditions. Verify that the 1 A current rating aligns with the circuit's maximum load current to prevent saturation.

Part Context

The SN3-200 belongs to the KEMET SN series of AC line filters. This series offers various inductance values for normal mode and common mode filtering. The SN3-200 specifically targets applications needing moderate inductance with high current handling capabilities in a compact through-hole package.

Replacement Considerations

Check for direct substitutes within the KEMET SN series with matching 10 µH inductance and 1 A current rating. Verify pinout compatibility and physical dimensions for PCB replacement.
