Overview
The PEMI1QFN/CT,315 is a single-channel RC Pi network EMI filter manufactured by NXP USA Inc. It features a resistance of 20 Ohms and a total capacitance of 23 pF. The component provides integrated ESD protection and operates within a temperature range of -40°C to +85°C. Packaged in an SC-101 (SOT-883) surface-mount case with a height of 0.50mm, it serves as a low-pass filter for signal lines.
Feature Summary
- Integrates ESD protection capabilities within the filter structure
- Utilizes an RC Pi topology for effective noise attenuation
- Designed for compact surface-mount applications
Applications
- LAN signal line protection
- PCS interface filtering
- WAN data line suppression
Procurement Notes
Verify the specific suffix CT against the official NXP datasheet to confirm the 20 Ohm resistance and 23 pF capacitance values. Ensure the SC-101 package dimensions match the design footprint. Confirm RoHS compliance status if required by the target market regulations before finalizing procurement orders.
Selection Notes
Select this component when a single-channel low-pass filter with integrated ESD protection is required for high-speed digital interfaces. The 20 Ohm resistance and 23 pF capacitance combination offers a specific cutoff frequency suitable for LAN and PCS applications. Consider the SOT-883 package size for space-constrained PCB layouts requiring minimal profile.
Part Context
This part belongs to the NXP PEMI1 series of EMI/RFI filters. These components are designed to suppress electromagnetic interference on data lines while providing electrostatic discharge protection. The series includes various resistance and capacitance combinations tailored for different signal integrity requirements across communication standards.
Replacement Considerations
Cross-reference with other NXP PEMI1 variants such as PEMI1QFN/RK,315 or PEMI1QFN/LR,315 only if their specific R/C values and attenuation characteristics align with the circuit design requirements. Verify pinout compatibility and package dimensions before substitution.
