EXB-24AB2CR8X

Attenuators Overview

The EXB-24AB2CR8X is a silicon-based chip attenuator from the Panasonic EXB-24AB series, designed for surface-mount applications. It provides a fixed attenuation of 2 dB with four internal elements. The component operates at an impedance of 100 Ohms and features a tolerance of 0.3 dB. Packaged in a compact 0404 (1010 Metric) concave case, it is qualified under AEC-Q100 standards for automotive reliability.

Attenuators Feature Summary

• Four-element internal architecture for precise signal attenuation
• Automotive-grade qualification compliant with AEC-Q100 standards
• Compact surface-mount design utilizing a 0404 concave package

Attenuators Applications

• RF signal conditioning in automotive electronic systems
• Impedance matching networks requiring 100 Ohm characteristics
• High-frequency circuit protection and level adjustment

Attenuators Procurement Notes

Verify current availability status as the component may be subject to discontinuation or limited supply constraints. Confirm that the 100 Ohm impedance specification aligns with your specific circuit requirements, distinguishing it from standard 50 Ohm variants. Ensure compliance with RoHS directives and check for any specific handling precautions associated with the concave package geometry during assembly.

Attenuators Selection Notes

Select this component when a 100 Ohm system impedance is required rather than the more common 50 Ohm configuration. The four-element design offers specific attenuation characteristics suitable for balanced lines or differential signals. Consider the AEC-Q100 qualification if the application demands automotive reliability standards. Verify that the 0404 package dimensions fit within the available PCB real estate constraints.

Attenuators Part Context

This part belongs to the EXB-24AB series of thin-film chip attenuators manufactured by Panasonic Electronic Components. These components are engineered for high-frequency applications where stable attenuation values are critical. The series utilizes silicon technology to achieve consistent performance across varying environmental conditions, supporting integration into complex RF front-end modules.

Attenuators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the specific 100 Ohm impedance and four-element configuration, direct replacements must be sourced from manufacturers offering identical electrical parameters and package dimensions.
