Overview
The PEMI4QFN/WP,132 is a surface-mount RC (Pi) EMI filter circuit manufactured by NXP USA Inc. It features a second-order low-pass configuration with four independent channels. The component integrates passive filtering elements with electrostatic discharge (ESD) protection capabilities. Key electrical parameters include a channel resistance of 200 Ohms and a total capacitance of 18.5 pF. It is housed in an 8-XFDFN package suitable for compact electronic designs.
Feature Summary
- Integrates RC Pi-filter topology for effective electromagnetic interference suppression
- Includes built-in electrostatic discharge protection for signal line safeguarding
- Provides multi-channel filtering capability within a single compact footprint
Applications
- Local Area Network (LAN) interface protection
- Personal Computer System (PCS) data line filtering
- Wide Area Network (WAN) signal conditioning
Procurement Notes
Verify the specific suffix 'WP' to confirm the 200 Ohm resistance and 18.5 pF capacitance values, as the PEMI4QFN family contains variants with different electrical characteristics. Ensure the ordering code matches the required channel count and package type. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring integrated EMI filtering and ESD protection for high-speed digital interfaces. The 200 Ohm resistance value is suitable for impedance matching in specific transmission lines. Consider the 8-XFDFN package dimensions for PCB layout constraints. Evaluate the total capacitance against signal integrity requirements for the target application bandwidth.
Part Context
This part belongs to the PEMI4QFN series of passive filter networks from NXP Semiconductors. The series offers various configurations with different resistance and capacitance values to suit diverse interface standards. The WP suffix specifically denotes the electrical parameters associated with this variant within the broader product family.
Replacement Considerations
Compatible substitutes within the same family include PEMI4QFN/RR,132 and PEMI4QFN/HM,132. Verify that alternative parts match the required resistance, capacitance, and channel count. Ensure the replacement maintains the same XFDFN package outline for mechanical compatibility.
