Overview
The PEMI8QFN/HR,132 is an RC (Pi) EMI filter manufactured by NXP USA Inc. It features eight channels with a resistance of 45 Ohms and a total capacitance of 21 pF. The component utilizes a 16-XFDFN exposed pad package measuring 3.30mm x 1.20mm. Designed for surface mount technology, it serves as a second-order low-pass filter to suppress electromagnetic interference in high-speed signal lines.
Feature Summary
- Integrates eight independent filtering channels within a compact footprint
- Provides effective suppression of electromagnetic interference through RC pi-network topology
- Optimized for high-speed data line protection applications
Applications
- High-speed interface signal line filtering
- USB port EMI suppression
- Display interface noise reduction
- General purpose high-speed data bus protection
Procurement Notes
Verify the specific suffix HR against official NXP documentation to confirm the exact resistance and capacitance values. Ensure the 16-XFDFN package dimensions match your PCB layout requirements. Confirm RoHS compliance status directly from the manufacturer's datasheet before finalizing procurement specifications.
Selection Notes
Select this component when eight-channel filtering is required for space-constrained designs. The 45-ohm resistance value suits specific impedance matching needs. Compare total capacitance against other variants like PEMI8QFN/RG to ensure compatibility with target signal frequencies and attenuation requirements.
Part Context
This part belongs to the PEMIxQFN series of EMI filters from NXP. These components are designed to replace discrete R-C networks, saving board space. The QFN package offers thermal performance advantages over traditional SMD resistors and capacitors for high-density mounting.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout compatibility and electrical parameters if considering alternative manufacturers or different suffixes within the same family.
