Overview
The Knowles Syfer SBSGC5000472MXT is a surface-mount LC(pi) EMI filter circuit designed for high-voltage applications. It features a capacitance of 4700 pF and a rated voltage of 500 VDC. The component utilizes X7R dielectric material with a tolerance of +/-20%. Packaged in an 1812 (4532 metric) footprint, it supports a continuous current of 5 A. This third-order low-pass filter provides one channel of signal conditioning.
Feature Summary
- Integrates LC(pi) topology for effective electromagnetic interference suppression
- Supports high DC voltage ratings up to 500 V
- Provides third-order low-pass filtering characteristics
- Designed for surface-mount assembly on printed circuit boards
Applications
- General-purpose EMI/RFI filtering circuits
- High-voltage signal line protection
- Power supply output filtering
Procurement Notes
Verify the specific suffix MXT against official datasheets to confirm packaging type and reel specifications. Ensure the X7R dielectric variant aligns with thermal requirements. Cross-reference the 1812 package dimensions with PCB layout constraints. Confirm RoHS compliance status through manufacturer documentation before integration.
Selection Notes
Select this component when a compact, high-voltage EMI solution is required. The 5 A current rating suits moderate power applications. Compare against the SBSGP series for similar performance in different packages. Evaluate the X7R temperature stability against C0G alternatives if stricter capacitance consistency is needed across wide temperature ranges.
Part Context
This part belongs to the Knowles Syfer SBSG series of integrated EMI filters. These components combine passive elements into a single SMD package to save board space. The series offers various capacitance values and voltage ratings tailored for industrial and commercial electronics requiring robust noise suppression.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with existing designs by matching electrical parameters and physical dimensions before considering alternative vendors.
