Overview
The PEMI2QFN/CP,115 is a second-order low-pass RC Pi-filter designed for EMI suppression. It features two channels with a resistance of 20 ohms and a total capacitance of 18.5 pF. The component integrates ESD protection diodes to safeguard downstream circuitry. It operates within a temperature range of -40°C to 85°C and is housed in a compact 6-XFDFN surface-mount package measuring 1.45mm by 1.00mm.
Feature Summary
- Integrates RC Pi-filter topology for effective high-frequency noise attenuation
- Includes built-in ESD protection diodes for downstream component safety
- Compact surface-mount design suitable for space-constrained layouts
Applications
- LAN interface protection
- PCS signal line filtering
- WAN data line EMI suppression
Procurement Notes
Verify the specific suffix CP indicates the 20-ohm resistance variant, as other suffixes like RR or LT denote different values. Confirm availability status, as this part may be discontinued or subject to supply constraints. Ensure the 6-XFDFN footprint matches the target PCB design requirements before finalizing procurement decisions.
Selection Notes
Select this component when a low-resistance filter path is required for high-current or low-impedance lines. The 20-ohm resistance offers less signal attenuation compared to higher-value alternatives. Verify that the 18.5 pF total capacitance meets the specific cutoff frequency requirements of the application without compromising signal integrity.
Part Context
This device belongs to the PEMIxQFN family of EMI filters from NXP USA Inc. These components are specifically engineered to address electromagnetic interference in high-speed digital interfaces. The QFN packaging allows for efficient thermal dissipation and reliable soldering in automated assembly processes.
Replacement Considerations
The PEMI2QFN/RR,115 serves as a functional substitute but utilizes a 100-ohm resistance value instead of 20 ohms. Designers must evaluate whether the increased impedance affects signal performance in their specific circuit configuration.
