PEMI2QFN/LE,115

Overview

The PEMI2QFN/LE,115 is a second-order low-pass RC (Pi) EMI filter manufactured by NXP USA Inc. It features two channels with a resistance of 65 Ohms per channel and a total capacitance of 8.5 pF. The component is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. Designed for data line protection, it integrates ESD suppression capabilities within the passive filtering network.

Feature Summary

• Integrates passive RC filtering with electrostatic discharge protection in a single surface-mount device
• Provides second-order low-pass attenuation for high-frequency noise reduction on data lines
• Utilizes a miniature 6-pin XFDFN footprint to optimize printed circuit board real estate

Applications

• Local Area Network (LAN) interfaces
• Personal Computer Systems (PCS)
• Wide Area Network (WAN) connections

Procurement Notes

Verify the specific suffix LE against current Nexperia or NXP documentation to confirm pinout and electrical tolerances. Check product lifecycle status as components may be discontinued or subject to last-time buys. Ensure RoHS compliance certificates are available if required for your manufacturing standards. Confirm package marking codes match the physical component received.

Selection Notes

Select this component when space-constrained designs require combined ESD protection and signal integrity filtering. The 65-ohm resistance value suits specific impedance matching requirements for certain data protocols. Compare total capacitance values against other variants in the PEMIxQFN family to ensure compatibility with target bandwidth specifications.

Part Context

This part belongs to the PEMIxQFN family of integrated passive filter networks. These devices combine multiple resistors and capacitors into a single monolithic structure. The family offers various channel counts and resistance values to address different interface needs while maintaining consistent physical dimensions for design flexibility.

Replacement Considerations

Consult official substitution lists for equivalent parts within the PEMIxQFN series. Verify that alternative components maintain identical pin configurations and thermal characteristics. Cross-reference datasheets to ensure comparable ESD performance levels and frequency response curves.
