PXV1220S-3DBN8-T

Attenuators Overview

The PXV1220S-3DBN8-T is a fixed RF attenuator manufactured by Susumu, designed for surface-mount applications in the 0805 (1220 metric) package. It provides a nominal attenuation value of 3.0 dB with a tolerance of +/-0.5 dB at a characteristic impedance of 50 ohms. The device operates within a frequency range of DC to 3 GHz and supports a maximum input power of 63 mW. Constructed using silicon technology, it offers stable performance for wireless and RF integrated circuit applications.

Attenuators Feature Summary

• Provides precise 3.0 dB signal attenuation with tight tolerance for consistent RF signal management
• Operates effectively across a wide bandwidth from DC up to 3 GHz
• Designed for high-reliability surface-mount integration in compact electronic assemblies

Attenuators Applications

• Wireless communication systems requiring fixed signal reduction
• RF test and measurement equipment calibration circuits
• Integrated circuit biasing and signal conditioning networks

Attenuators Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration when sourcing. Confirm that the manufacturer designation remains Susumu, as similar part numbers may exist under different branding or legacy naming conventions. Ensure the order quantity aligns with standard reel requirements if applicable. Cross-reference the exact model string against official distributor catalogs to avoid confusion with temperature-compensated variants or different attenuation values within the same series.

Attenuators Selection Notes

Select this component when a fixed 3 dB loss is required in a 50-ohm system operating below 3 GHz. Consider the 63 mW power rating to ensure thermal stability during continuous wave operation. The 0805 footprint allows for automated pick-and-place assembly. Evaluate if the standard silicon construction meets the environmental temperature specifications for the intended deployment environment compared to alternative thin-film technologies.

Attenuators Part Context

This component belongs to the PXV series of fixed attenuators from Susumu, which are engineered for high-frequency applications. The series utilizes silicon-based technology to deliver consistent impedance matching and attenuation accuracy. These devices are categorized under wireless and RF integrated circuits, serving as essential passive components for signal level control in modern telecommunications hardware.

Attenuators Replacement Considerations

Public confirmed substitute part numbers include PXV1220S-3DBN4-T and PXV1220S-3DBN6-T for variations in attenuation or packaging. Other manufacturers offer equivalent 3 dB, 50-ohm, 0805 SMT attenuators, but direct electrical equivalence must be verified against the original datasheet parameters.
