7442335900

Overview

The Würth Elektronik 7442335900 is a surface-mount common-mode choke from the WE-CNSW HF series, designed for signal line filtering. It features two lines with an impedance of 90 Ohms at 100 MHz and a maximum DC resistance (DCR) of 270 milliohms. The component supports a rated current of 500 mA and operates within a temperature range of -40°C to 105°C. It holds AEC-Q200 certification and utilizes a compact horizontal package measuring 1.20mm x 1.00mm x 1.10mm.

Feature Summary

AEC-Q200 qualified for automotive reliability standards
Shielded design to minimize electromagnetic interference
Compact horizontal footprint suitable for space-constrained layouts

Applications

Automotive electronic systems requiring EMI suppression
High-speed data line filtering in consumer electronics
Signal integrity protection in industrial control interfaces

Procurement Notes

Verify the specific suffix and packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the AEC-Q200 qualification status aligns with your project's automotive or high-reliability requirements. Ensure the 500mA current rating and 90 Ohm impedance specifications meet the target circuit's noise suppression needs without causing excessive signal attenuation.

Selection Notes

Select this component when a shielded, low-profile common-mode choke is required for high-frequency signal lines. The 90 Ohm impedance at 100 MHz provides effective noise attenuation for digital signals. The 270 milliohm DCR ensures minimal voltage drop across the line. Consider the 1.20mm x 1.00mm footprint for dense PCB designs where vertical height is limited to 1.10mm.

Part Context

This part belongs to the WE-CNSW HF series of surface-mount common-mode chokes. The series is characterized by its small form factor and high shielding effectiveness. It is intended for applications demanding robust EMI performance in tight spaces. The component is manufactured by Würth Elektronik, a specialist in passive components and electromechanical technology.
