Overview
The PEMI1QFN/WG,315 is a single-channel RC (Pi) EMI filter manufactured by NXP USA Inc. It functions as a second-order low-pass filter designed for surface-mount applications. The component integrates a resistance of 200 Ohms and a total capacitance of 11 pF within a compact SOT-883 package, also identified as SC-101. This configuration provides effective attenuation for high-frequency noise while maintaining signal integrity in sensitive circuits.
Feature Summary
- Integrates RC Pi-filter topology for second-order low-pass filtering
- Compact SOT-883 surface-mount package design
- Single-channel configuration for dedicated line protection
Applications
- High-speed data line EMI suppression
- RFI filtering in portable electronic devices
- Signal conditioning for sensitive input/output interfaces
Procurement Notes
Verify the specific suffix WG against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprint dimensions for the SOT-883 package. Confirm RoHS3 compliance status if required by regional regulations. Cross-reference the part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a compact, integrated solution for second-order low-pass filtering is required. The fixed 200 Ohm resistance and 11 pF capacitance values are optimized for specific impedance matching and cutoff frequency requirements. Consider the small form factor for space-constrained designs where discrete components would exceed available board area.
Part Context
This component belongs to the PEMIxQFN series of EMI/RFI filters from NXP Semiconductors. These devices are engineered to suppress electromagnetic interference in high-speed digital and RF applications. The series offers various package options and electrical configurations to suit different circuit density and performance needs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternatives from other manufacturers, ensuring package compatibility and electrical parameter alignment.
