Overview
The Knowles Syfer SBSMP2000154MXT is a third-order low-pass LC (Pi) EMI filter circuit designed for high-performance noise suppression. It features a capacitance of 0.15 µF with a tolerance of ±20% and utilizes X7R dielectric material. The component supports a continuous current rating of 20 A and operates within a voltage range up to 200 VDC. It is housed in a surface-mount package with dimensions of 6.6 mm by 5 mm, suitable for PCB integration.
Feature Summary
- Integrates LC Pi-filter topology for effective electromagnetic interference attenuation
- Supports high continuous current handling capabilities
- Utilizes stable X7R ceramic dielectric for consistent performance
Applications
- Power supply input filtering
- Motor drive circuits
- Industrial control systems
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 20 A current rating aligns with your system's thermal management requirements. Ensure the 6.6x5 mm footprint matches your PCB layout constraints. Check for any specific handling instructions regarding the surface-mount termination style.
Selection Notes
Select this component when a compact, high-current EMI solution is required for power lines. The integrated Pi-filter design reduces component count compared to discrete solutions. Consider the X7R temperature characteristics if operating near the upper limits of the specified range. Verify that the 200 VDC rating exceeds the maximum peak voltage in the application circuit.
Part Context
This part belongs to the Knowles Syfer family of passive components, specifically categorized under EMI/RFI filters. It represents a move towards integrated filter solutions that combine multiple passive elements into a single surface-mount package. This approach simplifies assembly and improves reliability in space-constrained electronic designs.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult the manufacturer for potential cross-references or updated series replacements.
