PEMI2STD/RG,115

Overview

The PEMI2STD/RG,115 is a second-order low-pass RC Pi-filter designed for EMI suppression and ESD protection. Manufactured by NXP USA Inc., it features two channels with an integrated resistance of 100 ohms per channel. The total capacitance is specified at 11 pF. This component utilizes a surface-mount SOT-665 package, measuring 2.4 mm in length, 1.8 mm in width, and 0.9 mm in height. It operates within a temperature range of -40°C to +85°C and provides attenuation of 25 dB from 800 MHz to 3 GHz.

Feature Summary

• Integrates passive RC filtering with electrostatic discharge protection diodes
• Provides signal line isolation through second-order low-pass architecture
• Compact surface-mount design suitable for high-density PCB layouts

Applications

• Data lines for mobile devices
• Local Area Network (LAN) interfaces
• Personal Communication Services (PCS) circuits
• Wide Area Network (WAN) connections

Procurement Notes

Verify the specific suffix RG against the official Nexperia datasheet to confirm the 100 Ohm resistance and 11 pF capacitance values. Ensure the SOT-665 package dimensions match the target footprint requirements. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when simultaneous EMI filtering and ESD protection are required on differential or dual single-ended lines. The 100 Ohm impedance matches standard data line characteristics. Consider the 11 pF capacitance value to ensure minimal signal distortion while achieving necessary high-frequency attenuation above 800 MHz.

Part Context

This device belongs to the PEMIxQFN/PEMI2STD family of integrated passive filter networks. These components combine multiple discrete functions into a single small outline package. The series offers various channel counts and impedance configurations to address diverse interface protection needs in consumer electronics and communication hardware.

Replacement Considerations

PEMI2STD/RP,115: Features 100 Ohm resistance but differs in capacitance (18.5 pF). Verify electrical compatibility if substituting. Other variants in the PEMI2STD family may offer different resistance or capacitance values; cross-reference the specific parameter table in the datasheet.
