Overview
The PEMI1QFN/RP,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 100 Ohms and a total capacitance of 18.5 pF within a compact SOT-883 package. This configuration provides effective attenuation for electromagnetic interference in high-frequency signal lines.
Feature Summary
- Integrates an RC Pi network topology for second-order low-pass filtering
- Provides EMI suppression with specified resistance and capacitance values
- Utilizes a compact SOT-883 surface-mount package for space-constrained designs
Applications
- High-speed data line protection
- RFI suppression in consumer electronics
- Signal integrity enhancement in portable devices
Procurement Notes
Verify the specific suffix RP against the official NXP datasheet to confirm the 100 Ohm/18.5 pF configuration. Ensure the SOT-883 footprint matches the PCB layout requirements. Confirm RoHS compliance status if required by the target assembly standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a second-order low-pass response is required for EMI reduction on single-ended lines. The fixed 100 Ohm resistance and 18.5 pF capacitance define the cutoff frequency characteristics. Consider the SOT-883 package dimensions for board space limitations. Evaluate insertion loss requirements against the filter's attenuation performance at target frequencies.
Part Context
This component belongs to the PEMI1QFN series of integrated EMI filters from NXP. These devices combine passive R and C elements into a single monolithic structure. The series offers various impedance and capacitance combinations tailored for different signal speeds. The RP variant specifically denotes the 100 Ohm/18.5 pF electrical specification.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative RC networks or discrete components if direct substitution is necessary. Consult NXP technical support for validated equivalents.
