Overview
The PEMI2QFN/RG,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 11 pF. The component provides ElectroStatic Discharge (ESD) protection for downstream circuitry. It is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm x 1.00mm x 0.50mm. Designed for operation between -40°C and 85°C, it offers an attenuation value of 25dB within the 800MHz to 3GHz frequency range.
Feature Summary
- Integrates passive RC filtering with ESD protection diodes for comprehensive signal line safeguarding
- Utilizes a Pi-network topology to achieve second-order low-pass filtering characteristics
- Provides high attenuation performance across the 800MHz to 3GHz spectrum
Applications
- Local Area Network (LAN) interfaces
- Personal Computer Systems (PCS)
- Wide Area Network (WAN) connections
Procurement Notes
Verify the specific suffix RG against the official datasheet to confirm the 100 Ohm/11pF configuration. Confirm RoHS3 compliance status as required by project specifications. Check current product lifecycle status, as this part may be discontinued or subject to change. Ensure the 6-XFDFN footprint matches the PCB design constraints before finalizing procurement decisions.
Selection Notes
Select this component when simultaneous EMI suppression and ESD protection are required on differential or dual single-ended lines. The 100 Ohm impedance matches standard transmission line requirements for many digital interfaces. The small XFDFN package is suitable for space-constrained mobile and portable electronic designs where board real estate is limited.
Part Context
This device belongs to the PEMIxQFN family of integrated passive filter networks. These components combine passive filtering elements with electrostatic discharge protection structures in a single surface-mount package. The family includes various channel counts and impedance values tailored for different interface standards and signal integrity requirements.
Replacement Considerations
PEMI2QFN/RR,115: Features identical 100 Ohm resistance but differs in total capacitance (21pF vs 11pF). Verify if the higher capacitance affects signal integrity for the specific application bandwidth.
