PEMI6QFN/HR,132

Overview

The PEMI6QFN/HR,132 is an EMI/RFI filter manufactured by NXP USA Inc., designed for surface-mount applications. It utilizes an RC (Pi) topology to provide low-pass filtering characteristics. The component features a total capacitance of 21pF and a resistance value of 45 Ohms. It is housed in a compact 12-XFDFN package with dimensions of 2.5mm x 1.2mm x 0.5mm, suitable for space-constrained electronic designs requiring effective noise suppression.

Feature Summary

• Employs RC Pi network topology for signal integrity enhancement
• Provides low-pass filtering to attenuate high-frequency interference
• Designed for surface-mount technology integration

Applications

• General-purpose EMI/RFI noise suppression in electronic circuits
• Signal line filtering in compact consumer electronics
• Power supply input/output noise reduction in portable devices

Procurement Notes

Verify the specific suffix HR against official NXP documentation to confirm the exact electrical parameters, as suffixes often denote variations in resistance or packaging. Ensure the XFDFN-12 package footprint matches your PCB design constraints. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a low-pass RC filter with specific impedance matching is required for EMI mitigation. The 45 Ohm resistance and 21pF capacitance values define the cutoff frequency characteristics. Consider the small form factor of the XFDFN package if board real estate is limited. Validate thermal performance requirements against the component's power dissipation capabilities.

Part Context

This part belongs to NXP's family of EMI/RFI filters, which are passive components used to suppress electromagnetic interference. These filters are critical for maintaining signal integrity and ensuring regulatory compliance in modern electronic systems. The QFN/LK and other variants within the series offer different pin configurations or electrical characteristics for diverse application needs.

Replacement Considerations

Cross-reference with PEMI6QFN/CR,132 for similar filtering functions, noting that it features 20 Ohm resistance instead of 45 Ohms. Verify compatibility with PEMI6QFN/LT,132 if alternative packaging or slight parameter variations are acceptable. Always consult official substitution guides to ensure electrical equivalence.
