Overview
The KEMET SU16VD-30030 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 30 µH measured at 1 kHz and supports a maximum current rating of 3 A. The component exhibits a DC resistance (DCR) of 70 mΩ, ensuring low insertion loss in power lines. With a physical diameter of 23 mm, it is constructed to meet ROHS compliance standards for environmental safety.
Feature Summary
- Provides effective attenuation of common mode noise on AC power lines
- Utilizes through-hole mounting for robust mechanical stability
- Constructed with materials compliant with ROHS environmental directives
Applications
- AC line filtering in consumer electronics
- Noise suppression in general-purpose power supplies
- Electromagnetic interference mitigation in household appliances
Procurement Notes
Verify the specific datasheet version provided by KEMET or authorized distributors to confirm exact electrical tolerances and thermal ratings. Ensure the selected component matches the required through-hole footprint dimensions and lead spacing for your PCB design. Cross-reference the 3 A current rating against your application's peak load requirements to prevent saturation.
Selection Notes
Select this component when designing circuits requiring common mode noise reduction for AC mains inputs. The 30 µH inductance value is suitable for standard line frequencies. Consider the 70 mΩ DCR impact on voltage drop if high efficiency is critical. Verify that the 3 A current rating exceeds the maximum operating current of the target equipment under all conditions.
Part Context
This part belongs to the KEMET SU16VD series of common mode chokes. These components are engineered for AC line filter applications, offering a balance of inductance and current handling capacity. The series is widely used in industries requiring reliable EMI suppression for devices connected to alternating current power sources.
Replacement Considerations
Consult official KEMET documentation for direct cross-references. Alternative parts must match the 30 µH inductance, 3 A current rating, and 70 mΩ DCR specifications. Ensure any substitute maintains the same through-hole package style and meets identical regulatory compliance standards.
