PEMI2STD/LE,115

Overview

The PEMI2STD/LE,115 is a second-order low-pass RC (Pi) EMI filter manufactured by Nexperia USA Inc. It features two channels with a resistance of 65 ohms per channel and a total capacitance of 8.5 pF. The component provides electrostatic discharge (ESD) protection and is housed in a compact SOT-665 surface-mount package measuring 0.024 inches in height. Designed for data line filtering, it operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates RC Pi-filter topology for effective electromagnetic interference suppression
• Includes built-in diodes for downstream component protection against electrostatic discharge events
• Utilizes a small-footprint surface-mount package suitable for space-constrained mobile device designs

Applications

• Data lines for mobile devices
• LAN, PCS, WAN interfaces
• Portable electronic equipment signal conditioning

Procurement Notes

Verify the specific suffix LE against current Nexperia documentation to confirm pinout and electrical characteristics, as ordering suffixes define physical and functional attributes. Confirm RoHS3 compliance status directly from the manufacturer's latest certification documents before integration into regulated products.

Selection Notes

Select this component when designing circuits requiring combined EMI attenuation and ESD protection for high-speed data lines. The 65-ohm resistance value should be evaluated against the target impedance of the transmission line to ensure minimal signal distortion while maintaining adequate noise filtering performance.

Part Context

This part belongs to the PEMIxQFN family of EMI filters designed for portable electronics. These components integrate passive filtering elements with active protection structures to safeguard sensitive input/output ports on mobile phones and handheld devices from both radio frequency interference and static discharge damage.

Replacement Considerations

PEMI2STD/RM,115 offers similar functionality but with different resistance and capacitance values (65 Ohms, 8.5pF). Verify that the alternative's electrical parameters match the original design requirements for impedance matching and cutoff frequency.
