Overview
The PEMI4QFN/RM,132 is a passive RC Pi-filter EMI/RFI filter network manufactured by Nexperia USA Inc. It features four independent channels designed for surface-mount applications. The component utilizes an 8-XFDFN package to provide compact footprint solutions. Electrical specifications include a channel resistance of 100 Ohms and a total capacitance of 16 pF per channel. This configuration supports second-order low-pass filtering characteristics suitable for suppressing electromagnetic interference in high-speed signal lines.
Feature Summary
- Integrates four independent passive filter channels within a single compact surface-mount package
- Provides effective suppression of electromagnetic interference through RC Pi-network topology
- Designed for robust performance in space-constrained electronic assemblies
Applications
- High-speed data line filtering in consumer electronics
- EMI suppression in portable computing devices
- Signal integrity enhancement in industrial control systems
Procurement Notes
Verify the manufacturer designation carefully, as sources may list NXP or Nexperia due to historical corporate divisions. Confirm the specific suffix RM indicates the 100 Ohm/16pF configuration distinct from other variants like RE or RT. Ensure the ordering code includes the trailing 132 tape-and-reel indicator if required for automated assembly processes.
Selection Notes
Select this component when a multi-channel solution is required to save board space compared to discrete components. Compare the 100 Ohm resistance value against target impedance requirements to ensure adequate attenuation without excessive signal degradation. Verify that the XFDFN package dimensions align with the available PCB land pattern and clearance constraints.
Part Context
This part belongs to the PEMI4QFN family of EMI filters, which offers various resistance and capacitance combinations tailored for different signal speeds. Variants such as PEMI4QFN/RK132 or PEMI4QFN/RW132 share the same physical footprint but differ in electrical parameters. The family is designed to replace multiple discrete resistors and capacitors, simplifying the bill of materials.
