PEMI1QFN/LR,315

Overview

The PEMI1QFN/LR,315 is a passive RC (Pi) EMI/RFI filter network manufactured by NXP USA Inc. It features a single channel configuration with a cutoff frequency of 65 Ohms and a total capacitance of 21pF. The component provides integrated ESD protection and is housed in a compact SOT-883 (SC-101) surface-mount package measuring 1.00mm x 0.60mm. Designed for signal conditioning, it functions as a second-order low-pass filter to suppress electromagnetic interference.

Feature Summary

• Integrates ESD protection within the passive filter structure
• Provides second-order low-pass filtering characteristics
• Utilizes a compact SC-101 surface-mount footprint

Applications

• Signal conditioning for high-speed data lines
• EMI suppression in portable electronic devices
• RFI filtering for sensitive input/output interfaces

Procurement Notes

Verify the specific suffix LR against the official NXP datasheet to confirm the 65 Ohm resistance and 21pF capacitance values. Ensure the SOT-883 package dimensions match the design constraints. Confirm RoHS3 compliance status if required by the target assembly process. Cross-reference the part number with current availability lists as product statuses may change.

Selection Notes

Select this component when a single-channel solution with integrated ESD protection is required for space-constrained designs. The 65 Ohm resistance value suits applications needing moderate attenuation without significant signal degradation. The small SOT-883 package allows for high-density PCB layouts. Consider the 21pF total capacitance impact on signal integrity for the specific data rate involved.

Part Context

This device belongs to the PEMIxQFN family of integrated passive filter networks. These components combine filtering and ESD protection in a single package to reduce board space and component count. The series includes variants with different channel counts and electrical specifications, all sharing similar mounting footprints for design flexibility.

Replacement Considerations

Check for direct substitutes within the PEMIxQFN family that offer compatible pinouts and electrical parameters. Verify that any replacement maintains the same ESD protection rating and package dimensions to ensure mechanical compatibility.
