Overview
The PEMI8QFN/CT,132 is an RC (Pi) EMI filter manufactured by NXP USA Inc. It features a second-order low-pass configuration with eight channels. The component utilizes an RC technology with a resistance value of 20 Ohms and a total capacitance of 23pF. It is housed in a 16-XFDFN package with an exposed pad, measuring 3.30mm in length and 1.20mm in width. The device height is 0.50mm. This surface-mount component is designed for effective electromagnetic interference suppression in compact electronic assemblies.
Feature Summary
- Eight-channel RC Pi filter topology for multi-line signal protection
- Second-order low-pass filtering characteristic for EMI/RFI attenuation
- Compact XFDFN package with exposed pad for thermal management
Applications
- High-speed data line protection in consumer electronics
- EMI suppression for USB or HDMI interfaces
- Signal integrity enhancement in mobile devices
Procurement Notes
Verify the specific suffix CT against the official Nexperia datasheet to confirm the exact termination and reel specifications. Ensure the ordering code matches the required packaging format. Cross-reference the part number with the manufacturer's current documentation to validate RoHS compliance status and availability before procurement.
Selection Notes
Select this component when multi-channel EMI filtering is required for high-speed digital signals. The 20-ohm resistance and 23-pF capacitance values are suitable for attenuating high-frequency noise without significantly distorting the signal waveform. Consider the XFDFN package dimensions for PCB layout constraints and thermal requirements.
Part Context
This component belongs to the PEMI series of EMI filters from Nexperia. These filters are designed to suppress electromagnetic interference on multiple lines simultaneously. The series offers various configurations to suit different application needs, providing a compact solution for maintaining signal integrity in dense electronic environments.
Replacement Considerations
Check for direct substitutes such as the PEMI8QFN/RG,132 variant, which may differ in packaging or tape-and-reel specifications. Verify electrical parameters and pinout compatibility before substitution. Consult the manufacturer's cross-reference guide for approved alternatives.
