PAT1632-C-7DB-T1

Overview

The Susumu PAT1632-C-7DB-T1 is a high precision chip attenuator from the PAT series, designed for surface mount applications. It provides a nominal attenuation of 7 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 power rating of 125 mW. Key electrical specifications include a maximum VSWR of 1.5 and a return loss of 16 dB. The component functions reliably across an operating temperature range of -55°C to +125°C.

Feature Summary

• High precision attenuation performance with tight tolerance
• Wide operational temperature range suitable for harsh environments
• Compact 1206 surface mount package design

Applications

• RF signal conditioning in wireless communication systems
• Impedance matching networks in test and measurement equipment
• Signal level adjustment in cellular infrastructure modules

Procurement Notes

Verify the specific suffix 'T1' corresponds to the standard tape and reel packaging configuration as defined by Susumu. Confirm that the 1206 footprint matches the target PCB layout dimensions. Ensure compliance with RoHS directives if required by the end application. Cross-reference the datasheet revision date to confirm current manufacturing status and parameter stability before finalizing procurement orders.

Selection Notes

Select this component when a precise 7 dB attenuation is required in a compact form factor. The 125 mW power rating suits low-to-medium power RF paths. Consider the 3 GHz bandwidth limit for higher frequency applications. The wide temperature range allows deployment in automotive or industrial sectors where thermal stability is critical for maintaining signal integrity over time.

Part Context

This part belongs to the Susumu PAT series of thin film chip attenuators. These components utilize silicon-based technology to achieve stable performance. The series offers various attenuation values and power ratings in standardized packages like 0402, 0603, and 1206, providing designers with flexible options for integrating passive RF control elements into modern electronic circuits.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with any alternative suppliers by matching the 1206 package, 7 dB value, 50 Ohm impedance, and 125 mW power rating strictly.
