Overview
The PEMI2QFN/RP,115 is a second-order low-pass RC (Pi) EMI filter manufactured by Nexperia USA Inc. It features two channels with a resistance of 100 Ohms per channel and a total capacitance of 18.5 pF. Housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm, the device provides attenuation of 25dB at frequencies between 800MHz and 3GHz. It operates within a temperature range of -40°C to 85°C and includes integrated ESD protection diodes for downstream component safety.
Feature Summary
- Integrates RC (Pi) topology for effective second-order low-pass filtering
- Includes built-in ESD protection diodes to safeguard connected circuitry
- Designed for high-density surface-mount applications with minimal footprint
Applications
- LAN data line protection
- PCS signal filtering
- WAN interface noise suppression
Procurement Notes
Verify the specific suffix RP indicates the 18.5pF capacitance variant, as other suffixes like RR or LT denote different electrical values. Confirm RoHS3 compliance status through official documentation. Check for obsolescence notices from Nexperia or NXP, as this component family has faced discontinuation events. Ensure the 6-XFDFN package availability matches your manufacturing requirements.
Selection Notes
Select this component when a dual-channel low-pass filter with integrated ESD protection is required for high-speed data lines. The 100-ohm resistance value aligns with standard impedance matching needs. Consider the 18.5pF total capacitance for specific cutoff frequency requirements. The small XFDFN package is suitable for space-constrained PCB layouts compared to larger discrete solutions.
Part Context
This part belongs to the PEMIxQFN family of EMI filters designed for data line protection. It combines filtering capabilities with electrostatic discharge protection in a single surface-mount device. The series is intended for use in telecommunications and computing applications where signal integrity and component protection are critical. Variants differ primarily in capacitance values and package types.
Replacement Considerations
Direct substitutes include PEMI2QFN/RR,115 (21pF total capacitance) and PEMI2QFN/LT,115 (different resistance/capacitance). Verify that the alternative variant's electrical parameters meet the original design specifications before substitution.
