Overview
The PEMI4QFN/CR,132 is a surface-mount RC (Pi) EMI filter circuit manufactured by NXP USA Inc. It features a four-channel configuration with a resistance of 20 Ohms per channel and a total capacitance of 21 pF. The component utilizes an 8-XFDFN package for compact integration. Designed as a second-order low-pass filter, it effectively attenuates electromagnetic interference in high-speed signal lines while maintaining signal integrity.
Feature Summary
- Integrates passive RC filtering networks with electrostatic discharge protection capabilities
- Provides multi-channel attenuation for simultaneous signal line protection
- Utilizes a compact surface-mount footprint to minimize PCB space consumption
Applications
- High-speed data interface protection
- USB port EMI suppression
- HDMI signal line filtering
- General-purpose ESD and EMI mitigation in consumer electronics
Procurement Notes
Verify the specific suffix designation against official NXP documentation to confirm exact electrical characteristics. Ensure the ordering code matches the required resistance and capacitance values. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a four-channel low-pass filter with integrated ESD protection is required. Compare the 20 Ohm resistance and 21 pF total capacitance against system impedance requirements. Evaluate the XFDFN package dimensions against available board real estate constraints.
Part Context
This part belongs to the PEMI4QFN family of EMI filter circuits from NXP. Variants within this series offer different resistance and capacitance combinations to suit various frequency response needs. The '132' suffix typically indicates tape and reel packaging for automated assembly processes.
Replacement Considerations
PEMI4QFN/RR,132 offers similar functionality but with different electrical parameters. Verify compatibility by comparing resistance and capacitance values against the original design requirements.
