Overview
The PEMI1QFN/RE,315 is a single-channel RC (Pi) EMI filter manufactured by NXP USA Inc. It features a resistance of 100 Ohms and a total capacitance of 8.5 pF. The component is designed for surface mount installation in an SC-101 or SOT-883 package. It operates within a temperature range of -40°C to 85°C. This device functions as a second-order low-pass filter to suppress electromagnetic interference.
Feature Summary
- Integrates a 100 Ohm resistor with 8.5 pF capacitance in a compact surface-mount package
- Provides second-order low-pass filtering characteristics for effective noise suppression
- Designed for single-channel signal line protection against EMI/RFI disturbances
Applications
- Signal line filtering in portable electronic devices
- Noise suppression in automotive infotainment systems
- EMI reduction in industrial control interfaces
Procurement Notes
Verify the specific suffix RE,315 to ensure correct packaging and tape configuration. Confirm that the SC-101/SOT-883 footprint matches the target PCB design. Check RoHS compliance status if required by project specifications. Ensure the operating temperature range meets environmental requirements.
Selection Notes
Select this component when a compact, single-stage RC filter is needed for high-frequency noise attenuation. The 100 Ohm resistance and 8.5 pF capacitance provide a specific cutoff frequency suitable for data lines. Consider the small package size for space-constrained designs requiring minimal insertion loss.
Part Context
This part belongs to NXP's family of passive EMI/RFI filters. It complements other variants like PEMI1QFN/RK,315 which may offer different impedance values. These components are typically used alongside active power management ICs in complex system-on-chip architectures to maintain signal integrity.
Replacement Considerations
PEMI1QFN/RK,315 offers similar functionality but may have different electrical parameters. Verify impedance and capacitance values before substitution. Other generic RC filters from various manufacturers can serve as alternatives if pin compatibility and thermal ratings align.
