Overview
The PEMI4QFN/CP,132 is a Surface Mount Device (SMD) EMI/RFI filter manufactured by NXP USA Inc. It functions as a second-order low-pass RC Pi network with four channels. The component features an integrated resistance of 20 Ohms and a total capacitance of 18.5 picofarads. It is housed in an 8-XFDFN package and is currently listed as obsolete.
Feature Summary
- Integrates a second-order low-pass RC Pi filter topology for effective noise suppression
- Provides four independent filtering channels within a single compact surface mount package
- Combines specific resistance and capacitance values to target high-frequency interference
Applications
- High-speed digital signal line protection
- Power supply input filtering
- Data bus noise attenuation
- EMI reduction in portable electronics
Procurement Notes
Verify the obsolete status of this part number before initiating procurement. Confirm availability through secondary market suppliers or authorized distributors holding existing stock. Ensure that the 8-XFDFN package dimensions match the target PCB footprint requirements for successful integration.
Selection Notes
Select this component when a four-channel low-pass filter with 20 Ohm resistance and 18.5 pF total capacitance is required. Consider the XFDFN package size for space-constrained designs. Evaluate the cutoff frequency characteristics against the specific signal integrity needs of the application circuit.
Part Context
This component belongs to the PEMIxQFN series of passive filter networks. It shares the same physical package form factor with other variants in the family, such as the PEMI4QFN/RR,132, which differ primarily in their internal resistance and capacitance values to suit different filtering specifications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineering teams should evaluate alternative components from the same manufacturer's current portfolio or design around available surplus inventory.
