PEMI1QFN/CE,315

Overview

The PEMI1QFN/CE,315 is a single-channel RC (Pi) EMI filter manufactured by NXP USA Inc. It features a second-order low-pass configuration with a resistance of 20 Ohms and a total capacitance of 8.5 pF. The component is housed in an SOT-883 package, also identified as SC-101 or 3-XQFN, with dimensions of 1.00mm x 0.60mm and a height of 0.50mm. Designed for surface mount installation, it provides effective noise suppression for high-frequency applications.

Feature Summary

• Integrates a passive RC Pi-filter network for efficient electromagnetic interference suppression
• Provides electrostatic discharge protection capabilities within the integrated circuit design
• Utilizes a compact surface-mount footprint suitable for space-constrained printed circuit board layouts

Applications

• High-speed data line filtering in portable electronic devices
• Noise reduction for clock signals in embedded systems
• EMI mitigation in automotive infotainment interfaces

Procurement Notes

Verify that the specific suffix CE corresponds to the required 20 Ohm resistance and 8.5 pF capacitance values, as other suffixes in the family may differ. Confirm the SOT-883 package compatibility with your assembly process. Ensure the component meets RoHS3 standards if environmental compliance is mandatory for your production requirements.

Selection Notes

Select this component when a compact, single-channel solution is needed for attenuating high-frequency noise on signal lines. The 20 Ohm resistor value offers a balance between insertion loss and signal integrity preservation. Consider the small form factor for dense PCB designs where discrete components would consume excessive area.

Part Context

This part belongs to the PEMIxQFN/2STD family from NXP Semiconductors. Variants such as PEMI1QFN/RK,315 and PEMI1QFN/CR,315 share similar packaging but may have different electrical characteristics. The family is designed specifically for integrated EMI/RFI filtering solutions in modern electronics requiring minimal component count.

Replacement Considerations

Direct substitutes include other variants within the NXP PEMI1QFN series, provided their electrical parameters match the 20 Ohm and 8.5 pF requirements. Cross-reference with Nexperia equivalents if supply chain diversification is necessary, ensuring pinout and thermal performance remain compatible.
