PXV1220S-4DBN7-T

Attenuators Overview

The PXV1220S-4DBN7-T is a fixed RF attenuator manufactured by Susumu, designed for wireless and RF integrated circuit applications. It provides a nominal attenuation of 4.0 dB with a tolerance of +/-0.5 dB at a characteristic impedance of 50 ohms. The component operates within a frequency range of 0 Hz to 3 GHz and supports a maximum power handling of 63 mW. Constructed using silicon technology, it is housed in an 0805 (2012 Metric) surface-mount package and supplied in tape and reel format.

Attenuators Feature Summary

• Utilizes silicon technology for compact surface-mount integration
• Maintains precise attenuation tolerance across the operational bandwidth
• Designed for high-frequency signal processing up to 3 GHz

Attenuators Applications

• Wireless communication systems
• RF integrated circuits
• Signal conditioning in RF front-ends

Attenuators Procurement Notes

Verify the complete part number including the suffix to ensure correct attenuation value and packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current production lifecycle status as components may be subject to obsolescence or supply chain adjustments.

Attenuators Selection Notes

Select this component when a fixed 4 dB attenuation is required in a 50-ohm system operating below 3 GHz. Ensure the PCB layout accommodates the 0805 footprint and that the power budget does not exceed 63 mW. Consider thermal management requirements if multiple attenuators are placed in close proximity on the board.

Attenuators Part Context

This device belongs to the PXV1220S series of thin-film or silicon-based fixed attenuators from Susumu. The series offers various attenuation values while maintaining consistent impedance and package dimensions, allowing for standardized design layouts across different signal path requirements in RF equipment.

Attenuators Replacement Considerations

Direct substitutes include other PXV1220S variants with different attenuation values such as PXV1220S-3DBN7-T or PXV1220S-5DBN7-T if the specific 4 dB value is not critical. Cross-brand replacements require matching the 0805 package, 50-ohm impedance, and 3 GHz frequency limit.
