Overview
The KEMET SN12-500J is a through-hole common mode choke from the SN-J series, designed for normal mode noise suppression. It features an inductance of 100 µH and a maximum DC current rating of 5 A. The component has a maximum DC resistance of 45 mΩ and operates within a temperature range of -40°C to 105°C. It utilizes a proprietary iron powder core material with high core loss characteristics. The unit measures approximately 28 mm in length, 22 mm in width, and 17 mm in height, housed in a plastic enclosure with UL 94 V-0 rated base and V-2 rated cover.
Feature Summary
- Proprietary iron powder core design for effective normal mode noise suppression
- High core loss characteristics suitable for interference applications
- Flame-retardant housing with UL 94 V-0 base and V-2 cover ratings
Applications
- General mode noise suppression circuits
- AC line filter applications
- Interference suppression in electronic equipment
Procurement Notes
Verify the specific part number SN12-500J against official KEMET documentation to confirm current availability and lead times, as market demand may cause fluctuations. Ensure compatibility with your circuit's voltage and current requirements before ordering. Check for RoHS compliance status and SVHC declarations relevant to your region's regulatory standards. Confirm packaging details such as tray quantities if applicable for your assembly process.
Selection Notes
Select this component when normal mode noise suppression is required alongside common mode filtering capabilities. The 5 A current rating and low DC resistance make it suitable for power line applications where minimal voltage drop is critical. Consider the physical dimensions and through-hole mounting style for PCB layout constraints. Evaluate the operating temperature range to ensure reliability under expected environmental conditions.
Part Context
The SN-J series represents KEMET's line of common mode chokes utilizing proprietary iron powder cores. These components are engineered for robust performance in noise suppression tasks. The SN12-500J specifically targets applications requiring moderate inductance and high current handling. This series is distinct from other KEMET inductor families by its focus on combined common and normal mode attenuation using specialized magnetic materials.
Replacement Considerations
Publicly confirmed substitute part numbers for SN12-500J were not found in the provided source data. Verify electrical parameters such as inductance, current rating, and DC resistance when considering alternative components from other manufacturers or different KEMET series.
