Overview
The PEMI1QFN/LT,315 is a passive EMI/RFI filter network manufactured by NXP USA Inc. It utilizes an RC Pi topology to provide signal conditioning for electronic circuits. The component operates as a low-pass filter with a total capacitance of 23pF and a resistance value of 65 Ohms. It is housed in a compact SOT-883 package, also designated as SC-101 or 3-XQFN, measuring 1.00mm x 0.60mm. This device is designed for surface-mount installation and is classified under signal conditioning components.
Feature Summary
- Integrates an RC Pi low-pass filter topology for effective EMI and RFI suppression
- Provides signal conditioning through combined resistive and capacitive elements
- Utilizes a miniature SOT-883 surface-mount package for space-constrained designs
Applications
- Signal line filtering in portable consumer electronics
- Noise reduction in high-speed data interfaces
- EMI mitigation in automotive infotainment systems
Procurement Notes
Verify the specific suffix LT against current manufacturer catalogs, as availability may vary. Confirm package dimensions and pinout compatibility with existing PCB footprints. Ensure that the RC parameters meet the target frequency attenuation requirements for the specific application environment before finalizing procurement.
Selection Notes
Select this component when a compact, passive solution is required for suppressing high-frequency noise on single-channel signals. The 65 Ohm resistance and 23pF capacitance define the cutoff characteristics. Consider the SOT-883 form factor for applications where board real estate is limited compared to larger QFN packages.
Part Context
This part belongs to the PEMIxQFN series of passive filter networks from NXP. These components are engineered for signal integrity improvement in digital and RF circuits. The series offers various configurations tailored for different impedance and capacitance needs within small footprint constraints.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other RC Pi filters if sourcing alternatives.
