Overview
The PEMI8QFN/LG,132 is an RC (Pi) EMI filter manufactured by NXP USA Inc. It features a second-order low-pass configuration with eight channels. The component utilizes a 16-XFDFN package with an exposed pad, measuring 3.30mm x 1.20mm. Each channel integrates a resistance of 65 Ohms and a total capacitance of 11pF. This surface-mount device is designed for effective electromagnetic interference suppression in compact electronic assemblies.
Feature Summary
- Eight-channel RC Pi network architecture for multi-line signal filtering
- Second-order low-pass topology for enhanced attenuation performance
- Compact 16-XFDFN surface-mount package with exposed thermal pad
Applications
- High-speed data line protection in industrial automation systems
- EMI suppression for multimedia interface connections
- Signal integrity enhancement in vision system components
Procurement Notes
Verify the specific suffix LG against official NXP documentation to confirm the exact resistance and capacitance values. Confirm RoHS3 compliance status through the manufacturer's current datasheet. Check for obsolescence notices as some variants are scheduled for discontinuation. Ensure the XFDFN package dimensions match the target PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when multi-channel EMI filtering is required within strict space constraints. The 65-ohm resistance and 11-pF capacitance values define the cutoff frequency characteristics. Consider the exposed pad for thermal management and grounding efficiency. Verify that the low-pass response aligns with the signal bandwidth requirements of the application without introducing excessive distortion.
Part Context
This component belongs to the i.MX ecosystem support range, often associated with NXP's industrial and multimedia processor families. While not a processor itself, it serves as a critical passive component for protecting high-speed interfaces connected to applications processors like the i.MX 8M Plus. It addresses noise immunity needs in complex digital environments.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult NXP official documentation for direct replacements or cross-reference compatible RC Pi filters with identical 65-ohm/11pF specifications in the 16-XFDFN package.
