PXV1220S-4DBN4-T

Attenuators Overview

The PXV1220S-4DBN4-T is a surface-mount RF attenuator manufactured by Susumu, designed for wireless and radio frequency integrated circuit applications. This component utilizes silicon technology to provide a fixed attenuation value of 4.0 dB with a tolerance of +/-0.5 dB. It operates within a frequency range of 0 Hz to 3 GHz and maintains a nominal impedance of 50 Ohms. The device features a compact 0805 (2012 metric) package and supports a maximum power rating of 63 mW. It is supplied in reel packaging, suitable for automated surface mount assembly processes.

Attenuators Feature Summary

• Fixed 4.0 dB attenuation with tight +/-0.5 dB tolerance
• Silicon-based construction for reliable RF signal control
• Compact 0805 surface mount footprint for space-constrained designs

Attenuators Applications

• RF signal level adjustment in wireless communication modules
• Impedance matching networks in radio frequency circuits
• Signal conditioning in integrated radio frequency systems

Attenuators Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm the 0805 package dimensions match your PCB layout requirements. Check RoHS compliance status through official manufacturer documentation before integration. Ensure the 63mW power rating aligns with your circuit's thermal management capabilities. Validate the 50 Ohm impedance specification against your system design parameters.

Attenuators Selection Notes

Select this component when a precise 4 dB reduction is required in a 50 Ohm system. Consider the 0805 package size for board space limitations. Evaluate the 63mW power handling against peak signal levels. Compare the 0 Hz to 3 GHz frequency response with application bandwidth needs. Review the silicon technology characteristics for temperature stability requirements.
