PEMI2STD/HR,115

Overview

The PEMI2STD/HR,115 is a passive EMI filter circuit manufactured by NXP USA Inc. It integrates an RC (Pi) network with electrostatic discharge (ESD) protection diodes for downstream components. The device features two channels with a resistance of 65 ohms and a total capacitance of 23 pF. It is designed as a second-order low-pass filter in a surface-mount SOT-665 package.

Feature Summary

• Integrates RC Pi-filter topology with ESD protection diodes
• Provides dual-channel signal filtering capability
• Designed for data line noise suppression

Applications

• Data line filtering
• Portable electronic devices
• Communication interfaces

Procurement Notes

Verify the specific suffix HR against the official NXP datasheet to confirm pinout and electrical characteristics. Ensure the component meets RoHS compliance requirements for your target market. Confirm package dimensions match the SOT-665 specification before integration into the PCB layout.

Selection Notes

Select this component when dual-channel EMI filtering and ESD protection are required in a compact footprint. The 65-ohm resistance and 23-pF capacitance values suit high-speed data lines requiring moderate attenuation. Compare with other PEMI2STD variants if different impedance or capacitance values are needed.

Part Context

This part belongs to the PEMI2STD family of EMI filter circuits from NXP Semiconductors. These devices combine passive filtering with active ESD protection in a single surface-mount package. The family offers various configurations to address different data rate and protection level requirements across consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes within the PEMI2STD series with different suffixes. Verify compatibility with existing PCB footprints and signal integrity requirements before substitution.
