Overview
The PEMI4QFN/HR,132 is a passive EMI filter circuit manufactured by NXP USA Inc. It features an integrated RC (Pi) network configuration designed for surface mount applications. The device provides four independent channels with a resistance of 45 Ohms per channel and a total capacitance of 21 pF. Packaged in a compact SMD format, it serves as an effective solution for suppressing electromagnetic interference in high-speed signal lines.
Feature Summary
- Integrates a 4-channel passive RC Pi-filter network for comprehensive EMI suppression
- Includes built-in ESD protection to safeguard sensitive downstream components
- Utilizes a compact surface-mount package design suitable for space-constrained PCB layouts
Applications
- High-speed data interface protection
- USB port filtering and noise reduction
- HDMI signal line EMI mitigation
- General-purpose EMI suppression in consumer electronics
Procurement Notes
Verify the specific suffix HR against the official NXP datasheet to confirm the 45 Ohm resistance value. Ensure the 132 reel quantity matches your production requirements. Cross-reference the RoHS status and moisture sensitivity level before integration into the manufacturing process.
Selection Notes
Select this component when a multi-channel EMI filter with integrated ESD protection is required. The 45 Ohm impedance is suitable for standard logic levels. Consider the 8-XFDFN package dimensions for footprint compatibility. Evaluate insertion loss characteristics against system bandwidth requirements.
Part Context
This part belongs to the PEMI4QFN family of EMI filter circuits from NXP Semiconductors. These devices are engineered to replace discrete R-C components, saving board space. The HR variant specifically denotes the 45 Ohm resistance characteristic within the series.
Replacement Considerations
Check for direct substitutes such as PEMI4QFN/HP,132 or PEMI4QFN/HM,132 if different resistance values are acceptable. Verify pinout compatibility and package dimensions before swapping.
