PAT0816-C-8DB-T5

Overview

The PAT0816-C-8DB-T5 is a surface-mount chip attenuator manufactured by Susumu, designed for RF and microwave applications. It provides a fixed attenuation of 8 dB with a nominal impedance of 50 Ohms. The component operates from DC to a maximum frequency of 10 GHz, ensuring signal integrity across a wide bandwidth. It features a maximum VSWR of 1.5 and supports a power rating of 64 mW. The device is housed in a compact 0603 (1608 metric) package, suitable for automated SMD/SMT assembly. It functions within an operating temperature range of -55°C to +125°C.

Feature Summary

• Fixed 8 dB attenuation value for precise signal level control
• Wideband operation from DC to 10 GHz
• Compact 0603 surface-mount package design
• High reliability with extended temperature range capability

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment signal paths
• Microwave circuit impedance matching networks
• Attenuation stages in radar and satellite receivers

Procurement Notes

Verify the specific ordering suffix matches the required tolerance and termination specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure PCB footprint aligns with standard 0603 dimensions to prevent soldering defects during reflow processes.

Selection Notes

Select this component when a fixed 8 dB reduction is required in 50-Ohm systems. Consider the 64 mW power limit for high-power environments. Evaluate the 1.5 VSWR against system return loss requirements. Compare package size constraints against alternative series like PAT1220 if larger footprints are permissible.

Part Context

This part belongs to the Susumu PAT series of thin-film chip attenuators. These components are engineered for high stability and low noise performance in RF circuits. The series offers various attenuation values and package sizes to accommodate different design constraints while maintaining consistent electrical characteristics across the frequency spectrum.

Replacement Considerations

Direct substitutes include other Susumu parts in the PAT series with identical 8 dB attenuation and 0603 packaging, such as variants with different power ratings if available. Cross-brand replacements require careful verification of parasitic parameters and thermal performance.
