ECLAMP2357NQTLT

Overview

The ECLAMP2357NQTLT is a third-order RC (Pi) low-pass EMI/RFI filter manufactured by Semtech Corporation. It integrates six independent channels within a single surface-mount package. The component utilizes a resistance value of 100 Ohms and a capacitance value of 12 pF per channel to attenuate high-frequency noise. It is housed in a 16-UFQFN exposed pad package, designed for compact circuit board layouts requiring efficient signal integrity management.

Feature Summary

• Integrates six independent filtering channels for multi-line signal protection
• Utilizes RC Pi topology for effective electromagnetic interference suppression
• Designed for surface mount assembly with an exposed pad for thermal performance

Applications

• High-speed data interface noise reduction
• Multi-channel signal line filtering in consumer electronics
• EMI suppression in compact mobile devices

Procurement Notes

Verify the specific suffix 'NQT' against the official Semtech datasheet to confirm the tape and reel configuration and moisture sensitivity level. Ensure the 16-UFQFN footprint matches the target PCB design. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement orders.

Selection Notes

Select this component when multiple signal lines require simultaneous low-pass filtering in a space-constrained environment. The 100 Ohm resistor and 12 pF capacitor values are suitable for attenuating high-frequency noise while preserving signal integrity on lower frequency data lines. Consider the UFQFN package size relative to available board real estate.

Part Context

This part belongs to the Semtech ECLAMP series, which focuses on circuit protection and signal conditioning solutions. The series includes various TVS diodes and filters designed to protect sensitive electronics from electrostatic discharge and electromagnetic interference. This specific model addresses the need for integrated multi-channel filtering rather than discrete component implementation.

Replacement Considerations

Consult Semtech's official cross-reference tools or distributor databases for verified substitute part numbers. Ensure any replacement maintains the 16-UFQFN package dimensions and identical electrical characteristics (100 Ohm R, 12 pF C, 6 channels). Verify pinout compatibility to prevent PCB redesign requirements.
