Overview
The PEMI1QFN/WM,315 is a surface-mount RC (Pi) EMI filter manufactured by NXP USA Inc. It functions as a second-order low-pass filter with one channel. The component features a resistance of 200 Ohms and a total capacitance of 16 pF. It is housed in an SC-101 or SOT-883 package with dimensions of 0.020 inches (0.50mm). The device operates within a temperature range of -40°C to 85°C and is supplied in tape and reel packaging.
Feature Summary
- Integrates RC Pi network topology for effective electromagnetic interference suppression
- Provides second-order low-pass filtering characteristics for signal integrity
- Designed for compact surface-mount applications in space-constrained environments
Applications
- High-speed data line protection in portable electronics
- EMI suppression on USB and other high-frequency interfaces
- Signal conditioning in consumer devices requiring noise reduction
Procurement Notes
Verify the specific suffix WM against the official NXP datasheet to confirm the 200 Ohm resistance and 16 pF capacitance values. Ensure the SC-101/SOT-883 package footprint matches the design layout. Confirm operating temperature ratings align with the target application environment before finalizing procurement.
Selection Notes
Select this component when a compact, second-order low-pass filter is required for single-channel EMI suppression. The 200 Ohm resistance and 16 pF capacitance combination suits specific impedance matching needs. Consider the SOT-883 package size for dense PCB layouts where standard filters are too large.
Part Context
This part belongs to the PEMI1QFN series of integrated passive devices from NXP. These components combine resistors and capacitors into a single package to save board space. The series offers various resistance and capacitance combinations tailored for different filtering requirements in modern electronic systems.
Replacement Considerations
Check for direct substitutes with identical 200 Ohm resistance and 16 pF total capacitance in the SOT-883 package. Verify pin compatibility and electrical performance equivalence with alternative manufacturers' RC Pi filters.
