EXB-24AB3GR8X

Attenuators Overview

The EXB-24AB3GR8X is a surface-mount RF attenuator manufactured by Panasonic Electronic Components. It features a 3 dB attenuation value and operates with a 300 Ohm impedance. The device supports a maximum frequency of 2.5 GHz and has a maximum power dissipation of 40 mW. It utilizes a 0404 (1010 Metric) concave package for SMD/SMT installation. The component functions within an operating temperature range of -55°C to +125°C. It is RoHS compliant and available in tape and reel packaging.

Attenuators Feature Summary

• Provides precise 3 dB signal attenuation for RF applications
• Operates at high frequencies up to 2.5 GHz
• Designed for surface mount technology with a compact 0404 package
• Supports wide thermal operation from -55°C to +125°C

Attenuators Applications

• RF signal conditioning circuits
• Impedance matching networks
• Signal level adjustment in communication systems

Attenuators Procurement Notes

Verify the specific impedance requirement, as this model is specified at 300 Ohms, which differs from other variants in the series. Confirm that the 0404 concave package footprint aligns with the PCB layout. Check for RoHS compliance status if lead-free processing is mandatory for the assembly line. Ensure the 40 mW power dissipation limit is sufficient for the target application's power levels.

Attenuators Selection Notes

Select this component when a 300 Ohm impedance match is required rather than the standard 50 Ohm or 100 Ohm configurations found in other EXB models. Consider the 0404 package size constraints for high-density designs. Evaluate the thermal performance requirements against the +125°C maximum operating temperature limit. Verify compatibility with the 2.5 GHz frequency range for the intended RF signals.

Attenuators Part Context

This part belongs to the EXB series of thin-film attenuators from Panasonic. These components are designed for stable attenuation in microwave and RF circuits. The EXB-24AB3GR8X specifically targets applications requiring 300 Ohm impedance, distinguishing it from the more common 100 Ohm or 50 Ohm variants like the EXB-24AB3CR8X.
