Overview
The PEMI1QFN/HP,315 is a single-channel EMI/RFI filter manufactured by NXP USA Inc. It utilizes an RC (Pi) topology configured as a second-order low-pass network. The component integrates specific passive values of 45 Ohms resistance and 18.5 picofarads total capacitance to attenuate high-frequency noise. It is housed in a compact SC-101 package, also designated as SOT-883, suitable for surface-mount assembly on printed circuit boards.
Feature Summary
- Integrates a second-order low-pass RC Pi-filter structure for effective signal conditioning
- Provides inherent Electrostatic Discharge (ESD) protection capabilities within the filter network
- Utilizes a compact SC-101 (SOT-883) surface-mount package for space-constrained designs
Applications
- High-speed digital signal line filtering in portable electronic devices
- EMI suppression for data interfaces requiring ESD protection
- Noise attenuation in RF front-end circuits
Procurement Notes
Verify the exact suffix 'HP,315' against official NXP documentation to confirm the specific RC parameter set. Ensure compatibility with SC-101/SOT-883 footprint requirements during PCB layout. Confirm RoHS compliance status through current manufacturer datasheets prior to procurement.
Selection Notes
Select this component when a single-channel solution combining low-pass filtering and ESD protection is required. The fixed 45 Ohm and 18.5 pF values define the cutoff characteristics; ensure these match the target frequency response needs. The small form factor makes it suitable for dense layouts where discrete components would exceed available board space.
Part Context
This part belongs to the PEMI series of integrated EMI/RFI filters from NXP. These components are designed to replace multiple discrete resistors and capacitors, simplifying the bill of materials. The series offers various configurations tailored for different channel counts and impedance requirements across consumer and industrial electronics.
Replacement Considerations
PEMI1QFN/LR,315 and PEMI1QFN/CR,315 are documented variants within the same family. Verify that the electrical parameters of alternative suffixes align with the specific design requirements before substitution.
