Overview
The KEMET SN8D-300 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 45 µH at 100 kHz and supports a maximum DC current of 2 A. The component has a maximum DC resistance of 52 mOhms. It operates within a temperature range of -25°C to +105°C and utilizes a ferrite core. The device is packaged for PCB mounting with radial leads.
Feature Summary
- Provides common mode noise suppression for AC power lines
- Utilizes a ferrite core for effective electromagnetic interference filtering
- Designed for through-hole PCB mounting
Applications
- AC power line filtering
- Electromagnetic interference suppression in power supplies
- General electronic equipment noise reduction
Procurement Notes
Verify the specific datasheet version for the SN8D-300, as parameters such as DC resistance may vary slightly between sources (e.g., 52 mOhms vs 72 mOhms). Confirm lead spacing and physical dimensions against the target PCB footprint. Ensure the operating temperature range meets the application requirements. Check RoHS compliance status if required by the manufacturing process.
Selection Notes
Select this component when a 45 µH inductance and 2 A current rating are required for common mode noise attenuation. Consider the through-hole package type for mechanical stability. Evaluate the thermal performance at the maximum rated current to ensure operation within the specified temperature limits. Compare alternative values in the SN series if different inductance or current ratings are needed.
Part Context
The SN8D-300 belongs to the KEMET SN series of AC line filters. This series includes various models with different inductance values and current ratings, all sharing similar through-hole mounting characteristics and ferrite core construction. The SN8D variant specifically denotes a standard filter configuration within this product family.
Replacement Considerations
Direct substitutes include other SN8D series components like SN8D-400 or SN8D-300JB, provided their electrical parameters match the design requirements. Verify that any replacement maintains the same package style and pinout compatibility.
