Overview
The KEMET SN12-800J is a through-hole normal mode choke designed for AC line filtering applications. It features an inductance of 270 uH and supports a maximum DC current of 3 A with a maximum DC resistance of 130 mOhms. The component utilizes proprietary iron powder core material to provide high core losses suitable for differential mode noise suppression. It operates within a temperature range of -40°C to +105°C and includes a UL 94 V-0 rated base and UL 94 V-2 rated cover for flame retardancy.
Feature Summary
- Proprietary iron powder core material for effective differential mode noise suppression
- High core loss characteristics optimized for power line filtering
- Flame retardant construction with UL 94 V-0 base and V-2 cover ratings
Applications
- AC line filters
- Power supply input stages
- Differential mode noise suppression
Procurement Notes
Verify the specific manufacturer part number against official KEMET documentation to confirm electrical parameters such as inductance, current rating, and physical dimensions. Ensure compatibility with required safety certifications and operating temperature ranges before integration into the design.
Selection Notes
Select this component for applications requiring robust differential mode attenuation on AC lines. Consider the 3 A current rating and 130 mOhms resistance when evaluating voltage drop and thermal performance. Verify that the through-hole mounting style fits the target PCB layout constraints.
Part Context
This component belongs to the SN series of AC line filters from KEMET. These filters are engineered for general-purpose power line noise reduction, utilizing iron powder cores to handle significant common and differential mode interference while maintaining compact physical dimensions for standard through-hole assembly processes.
Replacement Considerations
Cross-reference with other SN-series variants or equivalent iron powder core chokes from different manufacturers if pinout or parameter adjustments are needed. Confirm that substitute parts meet the same UL flammability ratings and current handling capabilities.
