Overview
The KEMET SS21VB-R150027 is a through-hole common mode choke belonging to the SS21VB series. It features an inductance of 2.7 mH and a DC current rating of 1.5 A. The component has a maximum DC resistance of 0.18 Ohms and operates within a temperature range of -40°C to +120°C. Rated for 500 V AC, it utilizes a bobbin winding style designed for effective electromagnetic interference suppression in power line applications.
Feature Summary
- Provides common mode noise suppression for differential signal lines
- Utilizes a through-hole bobbin construction for robust mechanical mounting
- Engineered for high-temperature operation up to 120°C
Applications
- Power supply input filtering
- Electromagnetic interference suppression in AC mains circuits
- Noise reduction in industrial control equipment
Procurement Notes
Verify the specific part number SS21VB-R150027 against official KEMET documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with existing PCB layouts regarding lead spacing and thermal requirements. Cross-reference certification marks such as UL or IEC if regulatory compliance is mandatory for the end application.
Selection Notes
Select this component when a 2.7 mH inductance at 1.5 A is required for common mode noise attenuation. Consider the 0.18 Ohm DC resistance impact on circuit efficiency. Verify that the 500 V AC voltage rating exceeds the peak line voltage of the target system. Confirm that the through-hole package fits the manufacturing constraints.
Part Context
This component is part of the KEMET SS21VB series of common mode chokes. These components are designed for general-purpose EMI filtering in power applications. The series offers various inductance and current ratings to suit different power line requirements while maintaining consistent physical and electrical characteristics across the family.
Replacement Considerations
Consult official KEMET substitution guides for verified equivalents. Ensure any replacement matches the 2.7 mH inductance, 1.5 A current rating, and 0.18 Ohm resistance. Verify that alternative parts meet the same safety certifications and temperature ratings.
