EXB-14AT3AR3X

Attenuators Overview

The EXB-14AT3AR3X is a surface-mount RF attenuator manufactured by Panasonic Electronic Components. It provides a fixed attenuation of 3 dB with a characteristic impedance of 50 ohms. The component utilizes an SMD/SMT termination type and is housed in a compact 0302 (0805 metric) package, measuring 0.8 mm in length, 0.6 mm in width, and 0.35 mm in height. It operates within a temperature range of -55°C to +125°C and meets the AEC-Q200 qualification standard for automotive applications.

Attenuators Feature Summary

• Fixed 3 dB attenuation value for signal level control
• 50 ohm characteristic impedance matching
• AEC-Q200 qualified for automotive reliability standards
• Compact 0302 surface-mount package design

Attenuators Applications

• RF signal path attenuation in wireless communication systems
• Impedance matching networks in automotive electronics
• Signal conditioning in high-frequency circuit boards

Attenuators Procurement Notes

Verify the specific ordering suffix against the official Panasonic datasheet to ensure correct packaging and tolerance specifications. Confirm that the AEC-Q200 qualification status aligns with your project's automotive reliability requirements. Cross-reference the 0302 package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Attenuators Selection Notes

Select this component when a precise 3 dB reduction is required in a 50 ohm system. The choice is driven by the need for a small form factor suitable for dense layouts. Consider the thermal operating range and automotive qualification if the environment demands high reliability. Ensure the frequency characteristics meet the application's bandwidth needs as specified in the electrical parameters.

Attenuators Part Context

This part belongs to the EXB-14AT series of RF attenuators from Panasonic. It is categorized under wireless and RF integrated circuits. The series offers various attenuation values and impedance options within the same compact package family, allowing designers to maintain consistent board layouts while adjusting signal levels across different product variants.

Attenuators Replacement Considerations

Consult the official Panasonic cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence based solely on package size or nominal resistance values. Verify that any alternative component matches the exact 3 dB attenuation, 50 ohm impedance, and AEC-Q200 qualification status required for the design.
