Overview
The PEMI1QFN/RT,315 is a single-channel passive RC (Pi) EMI filter from the NXP PEMIxQFN family. It features a second-order low-pass configuration with a total resistance of 100 Ohms and a total capacitance of 23pF. The component is housed in an SC-101 package, also designated as SOT-883 or XQFN3, with a maximum height of 0.50mm. This surface-mount device is designed for data line filtering applications requiring compact form factors.
Feature Summary
- Integrates a Pi-filter topology for effective high-frequency noise attenuation
- Provides ESD protection capabilities alongside signal filtering
- Utilizes a compact 3-pin surface-mount footprint suitable for space-constrained designs
Applications
- Data line filtering in portable electronic devices
- EMI suppression for USB and other high-speed interfaces
- Signal integrity enhancement in consumer electronics
Procurement Notes
Verify the specific suffix RT against the manufacturer's current datasheet to confirm the exact R and C values, as suffixes denote specific component configurations within the PEMI1QFN family. Ensure the ordering part number matches the required package type and RoHS compliance status before procurement.
Selection Notes
Select this component when a single-channel, low-profile EMI filter is required for data lines. The 100 Ohm resistance and 23pF capacitance define the cutoff characteristics. Compare against other suffix variants if different impedance or capacitance values are needed for specific frequency requirements.
Part Context
This part belongs to the NXP PEMIxQFN series, which includes integrated passive filters available in 1, 2, 4, 6, and 8-channel configurations. The PEMI1QFN variant specifically offers a single-channel solution. The RT suffix indicates the specific resistor and capacitor values within this product line.
Replacement Considerations
Direct substitutes may include other PEMI1QFN variants with identical electrical parameters but different suffixes, such as PEMI1QFN/RK,315 or PEMI1QFN/CP,315, provided their specific R and C values match the design requirements. Verify pinout compatibility.
