Overview
The PEMI4QFN/WK,132 is a surface-mount EMI/RFI filter circuit manufactured by NXP USA Inc. It features an RC (PI) topology with four channels. The component integrates passive filtering elements consisting of resistors and capacitors to suppress electromagnetic interference. Key electrical parameters include a resistance value of 200 Ohms and a total capacitance of 13.5 pF. It is housed in an 8-XFDFN package and supports an operating temperature range from -40°C to 85°C.
Feature Summary
- Integrates RC PI-filter network for effective EMI suppression
- Includes built-in ESD protection capabilities
- Compact surface-mount design suitable for space-constrained layouts
Applications
- Local Area Network (LAN) interfaces
- Personal Computer System (PCS) data lines
- Wide Area Network (WAN) connections
Procurement Notes
Verify the specific suffix 'WK' against official NXP documentation to confirm the exact resistance and capacitance values. Ensure the package type matches the required PCB footprint. Confirm RoHS compliance status through the manufacturer's current datasheet or ordering information before finalizing procurement decisions.
Selection Notes
Select this component when designing circuits requiring integrated EMI filtering and ESD protection for high-speed digital interfaces. The 200 Ohm resistance and 13.5 pF capacitance values are optimized for specific impedance matching requirements in LAN and WAN applications. Consider the thermal range and package size during layout planning.
Part Context
This part belongs to the PEMI4QFN family of multi-channel EMI filters from NXP Semiconductors. Variants within this series differ primarily in their internal resistor and capacitor configurations to suit various signal line characteristics. The '132' suffix typically denotes tape-and-reel packaging quantities.
Replacement Considerations
Check for direct substitutes such as PEMI4QFN/WG,132 or PEMI4QFN/WP,132 if different R/C values are acceptable. Verify pin compatibility and package dimensions before substituting any alternative part number.
