CLJ-2-203

Overview

The CLJ-2-203 is a surface-mount common mode choke manufactured by Amgis, LLC. It features two lines and provides an inductance of 20 mH at 100 kHz. The component has a typical DC resistance (DCR) of 1.8 Ohms and a current rating of 140 mA. Designed for compact electronic assemblies, it utilizes a surface mount package to facilitate automated placement.

Feature Summary

• Provides common mode noise suppression for dual-line circuits
• Utilizes surface mount technology for automated assembly integration
• Engineered with specific inductance characteristics for signal integrity

Applications

• Signal line filtering in compact electronic devices
• Noise suppression in data transmission interfaces
• EMI reduction in portable consumer electronics

Procurement Notes

Verify the manufacturer designation as Amgis, LLC when sourcing this component. Confirm the part number CLJ-2-203 matches the required 20 mH inductance and 140 mA current rating specifications. Ensure the surface mount package type aligns with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-current, high-inductance solution is required for surface-mounted applications. The 140 mA rating suits low-power signal lines rather than high-current power paths. Consider the 1.8 Ohm DCR impact on voltage drop within the circuit design constraints.

Part Context

This component belongs to the CLJ-2 series of common mode chokes from Amgis, LLC. The series offers various inductance values tailored for different filtering needs. The CLJ-2-203 specifically targets applications requiring 20 mH impedance at standard test frequencies.

Replacement Considerations

The Würth Elektronik part number 7448640417 is listed as a comparison point. Note that the 7448640417 is a through-hole component with different electrical ratings, requiring significant design adjustments if substituted.
