Overview
The PEMI4QFN/HG,132 is an SMD RC (Pi) EMI filter circuit manufactured by NXP USA Inc. It features a second-order low-pass configuration with four channels. The component utilizes an 8-XFDFN package and incorporates specific passive elements for signal integrity. Key electrical parameters include a resistance value of 45 Ohms and a total capacitance of 11 pF per channel. This device is designed to suppress electromagnetic interference in high-speed data lines while maintaining signal quality.
Feature Summary
- Integrates a second-order low-pass RC Pi-filter network for effective noise attenuation
- Provides four independent filtering channels within a compact surface-mount footprint
- Designed for EMI/RFI suppression in high-speed digital interfaces
Applications
- High-speed data line protection in consumer electronics
- EMI suppression for USB and display interfaces
- Signal integrity enhancement in mobile devices
Procurement Notes
Verify the exact suffix HG against official NXP documentation to confirm the 45 Ohm / 11 pF specification. Ensure the XFDFN-8 package matches your PCB land pattern. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest datasheet revision.
Selection Notes
Select this component when a 4-channel low-pass filter with 45 Ohm series resistance is required. The 11 pF total capacitance suits applications needing moderate filtering without excessive signal delay. Compare against other PEMI4QFN variants if different impedance or capacitance values are necessary for the target circuit design.
Part Context
This part belongs to the PEMI4QFN family of EMI filter circuits from NXP Semiconductors. These components are engineered for compact designs requiring multi-line noise suppression. The HG suffix specifically denotes the 45 Ohm / 11 pF variant within this product line, distinguishing it from other resistance-capacitance combinations available in the series.
Replacement Considerations
Direct substitutes may include other PEMI4QFN variants with identical 45 Ohm / 11 pF specifications. Verify pinout compatibility and thermal performance before substitution. Consult NXP's official replacement guide for cross-referenced part numbers with matching electrical characteristics.
