PAT0816-C-4DB-T5

Overview

The PAT0816-C-4DB-T5 is a high precision chip attenuator manufactured by Susumu. It provides an attenuation value of 4 dB with a 50 Ohm impedance. The device operates from DC to 10 GHz and supports a maximum power rating of 64 mW. It features a maximum VSWR of 1.5 and utilizes a 0603 (0816 metric) surface mount package. The component functions within a temperature range of -55°C to +125°C.

Feature Summary

• High precision silicon-based construction for stable RF signal attenuation
• Compact 0603 surface mount footprint facilitating automated PCB assembly
• Wide frequency operation extending from DC up to 10 GHz

Applications

• RF signal path conditioning in wireless communication systems
• Test and measurement equipment requiring precise signal reduction
• Mobile device front-end circuitry for level adjustment

Procurement Notes

Verify the specific suffix T5 against official Susumu documentation to confirm reel packaging specifications. Ensure the 0603 package dimensions align with the target PCB land pattern. Confirm that the 64 mW power rating meets the thermal requirements of the intended application environment without derating issues.

Selection Notes

Select this component when a 4 dB fixed attenuation is required at 50 Ohms within a compact form factor. Consider the 10 GHz frequency limit and 64 mW power handling capabilities relative to system signals. Evaluate the -55°C to +125°C operating range against environmental constraints compared to larger packages like 0805 or 1206 variants.

Part Context

This part belongs to the Susumu PAT series of high precision chip attenuators. These components are designed as direct replacements for discrete resistor networks, offering superior performance in RF applications. The series includes various attenuation values and package sizes to support diverse miniaturization needs in modern electronics.

Replacement Considerations

Cross-reference with other Susumu PAT series parts such as PAT0816-C-6DB-T5 for different attenuation levels. Verify compatibility with alternative manufacturers' 0603 4dB attenuators by comparing VSWR and power ratings.
