Overview
The EMIF08-2005QEJ is a second-order RC (Pi) EMI filter manufactured by STMicroelectronics. It integrates ESD protection capabilities within a compact surface-mount package. The device features a resistance value of 200 ohms and a capacitance of 45 pF. It is housed in a 16-pin QFN package with a height of 1.00 mm. This component is designed to suppress electromagnetic interference in systems exposed to such disturbances.
Feature Summary
- Integrates EMI/RFI noise suppression with electrostatic discharge protection
- Utilizes a second-order RC Pi-filter topology for effective signal conditioning
- Designed for surface-mount installation in space-constrained applications
Applications
- Systems subjected to electromagnetic interferences
- High-speed data line filtering
- Portable electronic devices requiring ESD protection
Procurement Notes
Verify the specific package variant and tape-and-reel configuration against the manufacturer's official datasheet before procurement. Ensure compatibility with automated placement equipment regarding the QFN footprint dimensions. Confirm RoHS compliance status through current documentation as manufacturing processes may evolve.
Selection Notes
Select this component when both EMI attenuation and ESD protection are required on a single channel or bus. The 200-ohm resistance and 45-pF capacitance values define the cutoff frequency characteristics. Evaluate the thermal performance and pin count requirements against the available 16-pin QFN form factor.
Part Context
This part belongs to the EMIF08 family of integrated filters from STMicroelectronics. These devices combine passive filtering elements with active protection structures. The family targets applications needing compact solutions for signal integrity and robustness against environmental electrical stress.
Replacement Considerations
Consult official substitution lists for equivalent RC filter configurations with similar impedance and capacitance values. Verify that any alternative maintains the same pinout and package dimensions for direct board replacement.
