DLW31SN102SQ2L

Common Mode Chokes Overview

The DLW31SN102SQ2L is a surface-mount common mode choke from the Murata DLW31S series, designed for EMI suppression in signal lines. It features a wirewound structure within a 1206 (3216 metric) package measuring 3.2mm x 1.6mm x 1.9mm. The component operates between -40°C and +85°C with a rated voltage of 50V. Key electrical parameters include an impedance of 1000 Ohms at 100 MHz, a maximum DC current of 230 mA, and a maximum DC resistance of 1 Ohm.

Common Mode Chokes Feature Summary

• Wirewound construction provides effective electromagnetic interference filtering for high-frequency noise.

Common Mode Chokes Applications

• Signal line EMI suppression
• High-speed data interface protection

Common Mode Chokes Procurement Notes

Verify the specific suffix SQ2L to confirm packaging type and terminal finish. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit. Confirm RoHS compliance status through official manufacturer documentation before integration.

Common Mode Chokes Selection Notes

Select this component when a 1206 footprint is constrained and 1000 Ohm impedance at 100 MHz is required. Evaluate the 230 mA current limit against peak signal currents. Consider the unshielded nature for placement relative to sensitive traces.

Common Mode Chokes Part Context

This part belongs to the DLW31S series of block-type EMI suppression filters. These components are engineered for compact electronic designs requiring reliable noise reduction in small form factors without compromising signal integrity.

Common Mode Chokes Replacement Considerations

Cross-reference with other DLW31S variants for different impedance values. Verify pinout compatibility and physical dimensions before substituting with generic equivalents.
