Overview
The KEMET SS30V-R180190 is a vertical mount common mode choke designed for AC line filtering applications. It features an inductance of 19 mH and supports a maximum DC current of 1.8 A. The component exhibits a maximum DC resistance of 230 mOhms and operates within a temperature range of -25°C to +120°C. Measuring 31 mm in length, 22.5 mm in width, and 33 mm in height, it utilizes through-hole termination for secure PCB integration.
Feature Summary
- Provides common mode noise suppression for AC line circuits
- Supports high current handling up to 1.8 A with low impedance
- Designed for vertical mounting via through-hole technology
Applications
- AC power line input filtering
- Electromagnetic interference (EMI) suppression in power supplies
- Noise reduction in electronic equipment connected to mains voltage
Procurement Notes
Verify the specific suffix and package dimensions against the official KEMET datasheet before ordering. Confirm that the thermal rating aligns with your system's operating environment. Ensure the through-hole footprint matches your PCB layout constraints. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when designing circuits requiring robust common mode attenuation at 1.8 A. The 19 mH inductance offers significant noise rejection for standard AC lines. Consider the vertical form factor for space-constrained enclosures where board area is limited but height is available. Validate thermal performance under continuous load conditions.
Part Context
This component belongs to the KEMET SS30V series of common mode chokes. The series is engineered for general-purpose AC line filtering tasks. It serves as a passive electromagnetic interference filter, protecting downstream electronics from conducted noise originating from the power source or radiating into the circuit.
Replacement Considerations
Check for direct substitutes within the SS30V series that match the 19 mH inductance and 1.8 A current rating. Verify pin compatibility and physical dimensions if replacing with components from other manufacturers. Ensure equivalent thermal and electrical specifications are maintained.
