- Tape-and-reel (T/R) packaging supporting automated high-volume automotive SMT assembly lines
Applications
The EXB-24AB2CR8X is designed for RF signal level adjustment in automotive telematics, GPS antenna circuits, V2X communication modules, and in-vehicle infotainment systems where precise 2 dB signal attenuation is needed across the DC to 2.5 GHz band. Its AEC-Q200 qualification makes it suitable for use in engine compartment and passenger cabin RF boards exposed to wide temperature swings from -40°C to +125°C. The 0404 package size minimizes insertion loss and parasitic inductance in 50-ohm RF trace routing on compact automotive PCBs.

Frequently Asked Questions
What frequency range and attenuation value does the EXB-24AB2CR8X provide?
The EXB-24AB2CR8X provides a nominal 2 dB attenuation across DC to 2.5 GHz, covering RF bands used in GPS (1.575 GHz), GLONASS (1.602 GHz), and lower cellular bands. The 4-pin resistive pi-network topology maintains a consistent 50-ohm impedance match throughout the specified frequency range, minimizing signal reflections in RF signal chains.
How does AEC-Q200 qualification affect the EXB-24AB2CR8X suitability for automotive RF designs?
AEC-Q200 qualification means the EXB-24AB2CR8X has passed standardized automotive passive component stress tests including thermal shock from -40°C to +125°C, humidity exposure, and vibration resistance per JEDEC standards. This qualification is mandatory for passive components used in automotive RF signal paths such as GPS, DAB radio, and 5G telematics modules that must survive 15-year vehicle lifetimes.
What is the PCB footprint of the EXB-24AB2CR8X 0404 package, and how does it compare to 0603 attenuators?
The 0404 package (1.0 mm x 1.0 mm, 1010 metric) is approximately 60% smaller in area than a standard 0603 (1.6 mm x 0.8 mm) attenuator chip. This size reduction shortens the RF signal path by several hundred micrometers in 2.5 GHz board designs, which is significant at wavelengths below 120 mm where parasitic reactances from longer PCB traces can degrade insertion loss flatness.
Can the EXB-24AB2CR8X be used in series with a GPS antenna input to reduce overdrive, and what power level is safe?
Yes, the EXB-24AB2CR8X is well-suited for inserting 2 dB of loss in a GPS antenna coaxial signal path to reduce strong signal overdrive at the LNA input. Panasonic chip attenuators in the EXB series are typically rated for 100 mW to 200 mW continuous RF power at the 0404 size, which exceeds the milliwatt-level signal powers present in passive GPS antenna circuits by a large safety margin.
