Overview
The PEMI8QFN/CM,132 is an RC (Pi) EMI/RFI filter manufactured by NXP USA Inc. It functions as a low-pass filter designed to suppress electromagnetic interference in electronic circuits. The component features eight channels and utilizes a specific resistance and capacitance configuration. Key electrical parameters include a resistance value of 20 Ohms and a total capacitance of 16pF per channel. It is housed in a compact 16-XFDFN package with exposed pads, suitable for surface-mount applications requiring efficient signal filtering.
Feature Summary
- Eight-channel RC Pi network architecture for comprehensive EMI suppression
- Low-pass filtering technology optimized for RF interference reduction
- Compact surface-mount design with exposed thermal pads
Applications
- Signal line protection in consumer electronics
- EMI suppression in mobile device interfaces
- Filtering in automotive infotainment systems
Procurement Notes
Verify the exact suffix designation during procurement, as variations such as CE or CP may exist within the same family. Confirm that the specified 20 Ohm resistance and 16pF capacitance values match the project requirements. Ensure the 16-XFDFN package dimensions align with the PCB footprint. Cross-reference the manufacturer datasheet for handling and storage conditions to maintain component integrity prior to assembly.
Selection Notes
Select this component when multi-channel EMI filtering is required in space-constrained designs. The RC Pi topology offers effective attenuation without active components. Consider the 20 Ohm impedance matching against source and load impedances to ensure optimal signal transmission while maintaining noise suppression. Evaluate the thermal performance capabilities provided by the exposed pad design for high-density layouts.
Part Context
This part belongs to NXP's range of passive EMI/RFI filters. It complements other variants like PEMI8QFN/CE,132 and PEMI8QFN/CP,132 which share similar form factors but may differ in specific parameter tolerances or packaging details. These filters are distinct from active PMICs or I/O expanders found in the same manufacturer's portfolio, focusing solely on passive signal conditioning.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative RC filter networks based on identical 20 Ohm and 16pF specifications. Ensure any replacement maintains the 16-XFDFN package outline to fit existing footprints.
