PEMI4QFN/LT,132

Overview

The PEMI4QFN/LT,132 is a Surface Mount Device (SMD) EMI/RFI filter belonging to the RC(PI) network category. It features a resistance value of 65 Ohms and a total capacitance of 23 pF. The component is manufactured by NXP USA Inc. and is designed for passive filtering applications in electronic circuits.

Feature Summary

• Integrates RC(PI) topology for effective electromagnetic interference suppression
• Includes built-in electrostatic discharge (ESD) protection capabilities
• Designed as a compact surface-mount solution for signal line conditioning

Applications

• Signal line filtering in portable consumer electronics
• EMI suppression in high-speed digital interfaces
• Protection of sensitive input/output ports against transient noise

Procurement Notes

Verify the specific suffix LT,132 to confirm the 65 Ohm resistance and 23 pF capacitance values. Ensure the package type matches the required PCB footprint. Confirm RoHS compliance status with the supplier prior to ordering, as lifecycle stages may vary by region.

Selection Notes

Select this component when a low-inductance PI-filter configuration is required for EMI reduction. The 65 Ohm resistance provides a specific impedance match for certain data lines. Verify that the 23 pF total capacitance meets the signal integrity requirements of the target application without causing excessive attenuation.

Part Context

This part belongs to the PEMI4QFN family from NXP Semiconductors, which offers various configurations of passive filter networks with integrated ESD protection. These components are typically used to protect I/O lines in microprocessors and interface controllers from electrical disturbances.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Other variants within the PEMI4QFN series, such as PEMI4QFN/LK or PEMI4QFN/CE, share similar packaging but differ in resistance and capacitance values.
